1. Does the PowerwoRx e3 work in any home?
Yes it does! The PowerwoRx is designed to go into any home with a single-phase circuit breaker panel with breaker
switches. For homes with the old screw in type fuses, the unit will work but additional hardware will be required. The
“energy savings” from PowerwoRx comes from how it deals with inductive loads or to put it in more common terms, how it
deals with motor driven appliances. If you say "yes" to only two or more of the following then you could be saving money
on your electric bill right now!
Is your central air conditioner / heat pump unit 3 years or older?
Is your forced air furnace 3 years or older?
Do you have a pool?
Do you have a well?
Do you use an air conditioner?
Is your refrigerator / freezer not EnergyStar rated?
Do you have more than one refrigerator / freezer?
Is your washer / dryer not EnergyStar rated?
Do you have a hot tub or a Jacuzzi?
Is your dishwasher not EnergyStar rated?Is your home over 2500 Square feet?
2. Installation Considerations?
PowerwoRx e3 must be installed by a licensed electrician (or equivalent in areas which do not issue licenses) or the 10-year
Warranty is void. The PowerwoRx e3 mounts next to a standard 100A or 200A single phase power panel. The unit’s two
supply wires (L1 and L2) are connected into a dedicated 220V, 20A or 30A breaker, ideally located at the top of the panel
but can be installed anywhere an opening exists. The neutral and ground are connected to their respective busses.
Questions regarding proper attachment and wiring should be directed to the electrician who can verify local and state codes
are being complied with.
Some specific questions from Electricians…..
1. A standard 200 Amp service has 1-Panel with a 200 Amp main breaker, usually located 3-5' from the meter. Should
the PowerwoRx e3 be tied in on the line-side of the main breaker or can a separate branch breaker be installed and
hook it up there? Could it even be installed to an existing 240 Volt breaker? ANSWER: The PowerwoRx e3 is
always installed on the switched side of the MAIN 200A breaker through a dedicated 20A or 30A double-pole
breaker. If the panel is full or there is not a double space available to add a double-pole breaker, space can be
made available by using two split, slim-line or “piggyback” breakers.
2. Does the 20A or 30A dedicated double pole breaker need to be at the top of the panel – there have been some
manufacturers who say it must? ANSWER: The dedicated double pole breaker can be installed in any open slot
that will accommodate a 240V breaker, regardless of whether it is at the top or bottom. The reason some have
suggested the breaker MUST be installed at the top of the panel is the assumption that a surge or spike will only be
stopped if it reaches the PowerwoRx e3 first. This is not true. The PowerwoRx Surge and Spike protection will
activate as soon as the line voltage exceeds the rated voltage +20%. Yes, it does take more time for the voltage
to travel to the bottom of the panel and then out to the PowerwoRx e3 then if it were connected to the top slot in
the panel. Regardless of location, the Surge or Spike will be stopped or arrested long before it can travel out from
the panel on branch circuits to appliances and electronics in the building.
3. Some areas require a 200A disconnect be mounted at the meter and from the disconnect run a line to a 200A Main
Lug Only panel inside the home. In that application, should the PowerwoRx e3 be located at the exterior disconnect.
ANSWER: In all cases, the PowerwoRx e3 is always installed on the switched side of the MAIN 200A breaker
through a dedicated 20A or 30A double-pole breaker, not on an exterior disconnect.
4. Many times the panel in the home is in a bedroom or other “living area” where people may not want to look at this
“green box” on the wall. Can it be located elsewhere, like in a closet in the attic, and if so how far from the panel is
this permitted? ANSWER: The PowerwoRx e3 can be remotely located in a closet or some other less-conspicuous
location. Distance from the panel should be minimized. Keep in mind that the two indicator lights are the only
indication that the PowerwoRx e3 is operating properly. Consequently the unit should be located in an area where
the lights can be checked. An inaccessible attic would not be the ideal location.
5. If there were enough room in the panel could the PowerwoRx e3 be placed inside the panel box? ANSWER: Because
the two indicator lights are the only indication that the PowerwoRx e3 is operating properly and code does not
permit the cover of the power panel to be modified, locating the unit inside the panel would not be the ideal
location.
6. Can the wires coming from the PowerwoRx e3 be shortened or lengthened and if so do they need to be the same
length? ANSWER: Yes the wires can be shortened to whatever length is necessary and no the wires do not need to
be the same length. Continental Power allows the lengthening of the wires to accommodate mounting the unit
further away from the panel than the current wiring allows. As a general rule, the length of the wires should be
kept as short as possible and electricians should follow standard electrical code regarding adding wire to the unit.
7. Can PowerwoRx e3 be mounted horizontally rather than just vertically and why does it have to be mounted at least
12” from the main panel? ANSWER: Due to the way the PowerwoRx is assembled internally, the ideal mounting
orientation is vertically (as instructed in the Installation Instructions) with the wires coming out the bottom.
Continental Power allows a horizontal mounting orientation with the cover on the top side and the wires coming out
on the right. In addition, the 12” requirement is being removed from the installation instructions.
8. Many "Custom" homes have one 400A meter and run from there with a line to each of (2) 200A panels in the home
with main breakers. If we locate one PowerwoRx e3 in just one of the panels are both panels protected? ANSWER:
One PowerwoRx e3 per 200A panel is required. If only one PowerwoRx e3 is installed, only one panel is protected.
In this case installing two PowerwoRx e3’s is recommended, one per 200A sub panel.
9. If a home or small business has two 200-amp main panels, does a PowerwoRx e3 need to be installed on both
panels? ANSWER: Typically one unit is recommended for each 200A panel. One reason you may want to only
install one unit is if the boxes are located next to each other, and the total electrical usage is low – typically in the
$200-$300 per month range. If the electrical usage is well above this level or the panels are not side by side, the
only way to adequately treat the panels and protect the attached appliances and electronics is to have a unit on
each panel. The PowerwoRx provides adequate treatment for typical home electrical usage, in other words for
typical inductive loads. If the electric bill is quite high – over $500 per month, a single PowerwoRx will not provide
the expected results.
10. If a home or small business has a 200 amp service and a 100 amp sub panel either next to, or in a remote location,
does a PowerwoRx e3 need to be installed on both panels, or one of the panels, & if so which panel? ANSWER: If
the 100A sub panel is located close by and total electrical usage is no more than $200-$300 per month, one
PowerwoRx is adequate. If the 100A sub panel is 100 yards away in another building, a second PowerwoRx on the
sub panel is suggested to insure the sub panel has adequate surge & spike protection, harmonic filtration, and PF
reduction. Of course it is also dependent on what reactive loads are tied to the sub panel. If there are little or no
reactive loads, and there are few appliances or electronics to protect, a unit on the sub panel would not be
warranted. Conversely, if there are a large number of reactive loads being powered by the sub panel, a separate PowerwoRx will be needed.
3. How long will the PowerwoRx e3 last?
It has a predicted lifespan of over 20 years and comes with a 10-year warranty. This claim is based upon the synergy
between the three components which protect each other and lessen the derating of components which is typical in “capacitor in a box” type products.
4. What is the PowerwoRx e3 Warranty?
The warranty on PowerwoRx e3 is the best in the industry – a full 10 year! The patent pending design and the quality of the
components used in the PowerwoRx e3 Whole House Energy Management System lets us offer this industry leading
warranty. No other manufacturer comes close. Even if the PowerwoRx e3 performs as it should in the event of a lightning
strike nearby, and the Industrial rated MOV’s which absorb the energy sacrifice themselves, Continental Power will repair or replace the unit.
In addition, a $25,000 warranty on the homeowners appliances AND electronics is included! For more details on this
warranty see the policy at www.continentalpowerworx.com website. It should be noted that the PowerwoRx only protects
against surges on the electrical lines, not on the Telephone or TV Cable. For 100% protection Telephone and Cable surge
protectors are needed.
Note: The $25,000 warranty on the homeowners appliances AND electronics applies to the residential PowerwoRx e3 only.
A PowerwoRx e3 installed in a commercial facility is not covered. The commercial 3-phase PowerwoRx have the same
industry leading 10-year product warranty, but do not have the appliance/electronics warranty. This is not a liability
insurance policy. The PowerwoRx, along with all products offered by Continental Power are insured by a multi-million dollar
manufacturer’s liability insurance policy.
5. How much current will the PowerwoRx e3 handle?
The PowerwoRx e3 is designed for 240V and 200A which is typical for residential applications. The PowerwoRx cannot be
damaged if used on an application which would be better served by a larger unit. The only down side would be the inability
to store as much reactive current required for the motors being used, which means that current must come from the utility.
In addition, where harmonic filtration is needed for larger “Commercial” applications, a line of 3-Phase Commercial PowerwoRx e3 units is available through Continental Power.
6. Will the PowerwoRx e3 affect any of my appliances and their normal use?
No, if anything, your motors will run about 10% cooler, which is good because heat is the enemy of a motor. PowerwoRx e3 reduces I2R line losses which improves voltage stability, improving motor performance.
7. Is the PowerwoRx e3 tested and approved by independent labs?
PowerwoRx e3 is UL listed and tested (PowerwoRx UL certificate is under the UL 508 “Industrial Control Equipment” category, UL Certificate # E320259, dated 3/27/08).
The technology is also recognized by the U.S. Department of Energy.
8. How much can I expect to save per month by using the PowerwoRx e3?
That depends on many factors. The size of your home, the amount of inductive motor load, and the amount you are paying
per kilowatt-hour for electricity, harmonic noise on your electrical lines, surge & spike issues, etc. Based upon customer
feedback by far the majority of users are seeing a savings but it is important to point out that some users have seen no
energy savings based upon initial power factor above 95%, low harmonics and other factors.
A few states have electric utilities which are beginning to penalize residential electric customers for poor power factor as
implementing charges for peak demand. In these locations the opportunity for savings by installing the PowerwoRx is increased significantly due to the PowerwoRx ability to eliminate Power Factor penalties and reduce peak demand.
9. How long will it take for the PowerwoRx e3 to pay for itself?
Looking strictly at Energy Savings the product can pay for itself within 2-4 years. This of course depends on individual
circumstances, number of appliances and age, electrical costs and usage patterns, the homes power factor as well as other
criteria. The other benefits can turn out to be the biggest benefit of all! Consider Surge & Spike Protection, as well as the
harmful effects of harmonic distortion. These invisible but very real threats to all electrical appliances and electronics in the
home can and will cause premature failure. Considering the significant investment in these appliances and electronics, often
totaling in the 10’s of thousands of dollars, the protection provided by PowerwoRx e3 could be the biggest money-savings
benefit of the product.
10. Is the PowerwoRx e3 easy to install and who is qualified to perform the installation?
Yes, but the PowerwoRx e3 must be installed by a licensed electrician or qualified electrical installer in areas where
electricians are not required to be licensed. Qualified installers can be HVAC contractors. It is ultimately the responsibility of
the Continental Power distributor to insure the installer is qualified. Continental Power does not evaluate installers as to their
qualifications and only in the event of a warranty claim will the qualifications of the installer be questioned. If the installer is
determined to not be qualified based upon local standards, and the product failure is attributable to improper installation, the
product warranty will be void.
Installation requires opening up of the electrical panel, exposing potentially dangerous high voltage wires. The unit comes
with complete installation instructions and installs in about 15-30 minutes as long as there is space to add a 20A or 30A
double pole breaker.
11. Why haven’t I heard of these products until now?
That’s easy; two words “cost effectiveness”. Up until recently, electric rates throughout America were cheap, costing us 2, 3
or 4 cents per kilowatt-hour. Now, electric rates are 8, 10, 12, 14, and 19 and in some cases New York City is 22 cents per
Kwh, and Hawaii is 33.5 cents per Kwh. At the cheaper rates the PowerwoRx e3 didn’t make sense, but at the current rates, it makes all the sense in the world.
12. What about PowerwoRx e3 for Surge Protection?
One of the most important features of the PowerwoRx e3 is the ability to protect the entire home against power surges. No
longer is there a need for so many individual surge protectors in the home. The PowerwoRx e3 provides a broad range of
protection for hardwired appliances and most home electronics such as appliances, televisions, satellite equipment,
entertainment systems, etc using Industrial-Rated MOV’s. The unit protects from power line surges as well as spikes caused
by internal wiring problems, loose connections and fluctuating demand from large motors such as vacuum cleaners, heating and cooling equipment, etc.
13. Is the PowerwoRx e3 Energy Star rated?
PowerwoRx e3 is not Energy Star rated because this type of product does not fit into the Energy Star rating system.
14. Does the PowerwoRx e3 save any energy on Resistive (non-motor) loads?
Resistive loads are equipment like incandescent lighting, electric resistant heating, electric hot water heaters and electric
ovens and ranges. These devices require no “magnetic power” or “reactive power” to operate; consequently they have no
negative impact on Power Factor. The energy savings capability of PowerwoRx e3 is achieved by storing the reactive power
which is typically wasted, and making it available for reactive loads as required. There is no energy savings from PowerwoRx e3 being attached to a purely resistive load.
15. Can the PowerwoRx e3 cause my electric bill to go up and does it use electricity when there is little or no power demand?
The PowerwoRx e3 will not cause the electric meter to turn on its own. The product does not “Use” energy – it captures
energy from reactive (motor) loads and then provides it back to the motors when they need it.
16. Mounting Considerations – what if the Residential Power Panel is flushmounted in an exposed area?
The PowerwoRx e3 is designed to be SURFACE MOUNTED only due to its size (5” deep) and the surface mount mounting
flange. Even if the 200A Power Panel is recessed and therefore flush mounted, the PowerwoRx e3 must still be surface
mounted. With several feet of wire to tie into the power panel, the PowerwoRx e3 can be mounted in a less obvious location.
Continental Power is developing a Flush Mount PowerwoRx e3 which will be released in mid 2009.
17. What is the difference between PowerwoRx e3 and other “Energy Savings” devices in the market?
There are over a dozen manufacturers of products that “look” similar and make similar claims as PowerwoRx e3 regarding
energy savings. These products are in many cases less expensive so what is the difference?
The numerous “Power Savings Devices” on the market today consist of two electrolytic capacitors in a box. The PowerwoRx
e3 contains:
‐ 2 Electrolytic Capacitors
‐ 2 Harmonic Filters
‐ 2 MOV’s for Surge/Spike protection
‐ Additional electronics
A comparison of the two products is like comparing a golf cart and a sports car. They are both considered transportation,
but the sports car has a lot more capability. As far as the literature goes, we all know that companies make all kinds of
claims. The PowerwoRx e3 has:
1. The best warranty in the business (10 years)
2. A patent pending product developed by a team of MIT PhD’s with no other product like it in the market
3. True Harmonic and Noise Filtration
4. True Surge & Spike Protection thanks to Industrial MOV’s
5. $25,000 warranty on connected appliances & electronics (see the end of this document).
PowerwoRx e3 is a premium product that has premium features. Consequently there is no comparable product on the
market today that combines all these features together.
There are several products on the market which provide individual features much like the PowerwoRx e3:
• Leviton 51120-1 Whole House Surge Suppressor, 1-Phase - single feature only for a home: $190
• Panamax MAX In-Wall Powerkit-Pro electronic Noise reduction unit, single feature only- but not a whole-house unit:
$299
• Facility Management Solutions Inc. Power factor correction device, single feature only for a home: $349.
Total cost of all 3 units: $838 and does not have many of the features and benefits of the PowerwoRx e3 PowerwoRx e3 by Continental Power Corporation - One unit, One installation and One low price!
18. Does the PowerwoRx e3 consume energy on its own?
No. The PowerwoRx e3 stores and supplies energy to the electrical appliances in the home, it does not directly consume
electricity. Consequently, if an amperage meter (current probe) is placed on the electrical lines leading to the PowerwoRx
e3, a reading of 2.5-3 amps will typically be shown. Even when no appliances are on, and therefore no electricity is being
consumed, there will still be current flow showing on the current probe. Most assume this translates into 400W of energy
being “used” which on an annualized basis will cost the homeowner well over $100 per year at current electric rates. The
truth is the PowerwoRx e3 “uses” no energy. This is easily proven by turning off all electrical loads and going to the Electric
Meter and reading the consumption – the meter will not be turning.
Another interesting test is to power a typical motor load like a bench grinder. Use a current meter to measure the inrush
current at start-up as well as the steady-state current draw with and without the PowerwoRx e3 in the circuit. With
PowerwoRx e3 activated the current draw at start-up and steady-state is typically reduced by over 30% thanks to the storing of the reactive energy by the PowerwoRx e3.
19. Is a company by the name of EcoQuest also selling the PowerwoRx e3?
EcoQuest International was granted exclusive distribution rights of the PowerwoRx e3 in June 2008. In March 2009
EcoQuest was foreclosed upon and another company purchased their assets. Because the new owners chose not to continue
with EcoQuest’s original contract, the new EcoQuest no longer has rights to the PowerwoRx product line, Trade Mark or any
intellectual property. Any product EcoQuest may be selling under the name PowerwoRx or another name is not based upon
the 15 year history and the thousands of satisfied customers.
Continental Power and its President Ed Kimmel has been a Power Conditioning solutions provider for over 15 years.
Continental Power owns the intellectual property for PowerwoRx and there is only one way to obtain the original PowerwoRxbrand, and that is through an authorized Continental Power Distributor.
20. Some Power Company Representatives have said Power Factor Correcting devices do not result in savings on the customer’s electric bill – why?
The following response was provided by Ed Kimmel, President of Continental Power:
I have fifteen years worth of data that I have shared with many engineers that have made the same statement as
above. I can tell you with 100% confidence that our systems do reduce kWh and kW usage as well as reduce or
eliminate power factor penalties and reduce harmonic distortion.
As you know, no two electrical systems are the same, and no two utility companies bill their customers exactly the
same. There are electric utility companies that charge more for kW and kWh usage than others. There are electric
utility companies that penalize a customer for poor power factor. We see much larger reductions in usage in less
efficient electrical system. This is to be expected. We also see shorter payback periods and larger ROI’s on electric
utilities with higher rates than others.
Power factor is just one third of the technology incorporated in the PowerwoRx Systems. We also install PowerwoRx
for noise reduction and protection, using MOV’s for surge and spike protection and harmonic filtration for noise
reduction.
In my fifteen years of installing our equipment I have never had a dissatisfied customer. This I have done by being
honest and upfront with every customer I have had. We do reduce kW and kWh usage!
Ed Kimmel, President
Continental Power Corporation
Most Power Companies do not charge a penalty for poor power factor. States currently charging a residential Power Factor
penalty include California and Texas with several others adding this provision in 2009. Regardless of power factor penalties,
PowerwoRx can and does save energy, but is important to understand that the amount of saved energy is dependent upon
an almost infinite number of factors so being able to predict what the savings is not possible.
Some of the factors which can lead to power savings beyond reducing reactive current by improving power factor include
reductions in harmonicas as well as surges & spikes. Feedback from customers has shown that the majority of homeowners
are seeing a savings on their electric bill, which is beyond the benefits provided by increased equipment life from reduced
harmonics and surge and spike protection.
21. Are there any tax incentives for buying the PowerwoRx e3 unit?
The PowerwoRx e3 could potentially qualify for a tax credit under the Energy Policy Act of 2005 for tax year 2009. On
September 17, 2008, The Energy Improvement and Extension Act of 2008 was passed by congress as part of the $700
Billion financial bail-out plan. For a complete summary of the bill see:
http://www.finance.senate.gov/sitepages/leg/LEG%202008/091708%20Staff%20Summary%20of%20the%20Energy%20Im
provement%20and%20Extension%20Act.pdf ) Here is the summary of the provision which could potentially benefit
homeowners:
§ 302 Extension & Modification of Credit for Energy-Efficiency Improvements to Existing Homes
The bill extends the tax credit for energy-efficient existing homes for 2009 under Section 25C, and includes energyefficient
biomass fuel stoves as a new class of energy efficient property eligible for a consumer tax credit of $300. The
proposal also clarifies the efficiency standard for water heaters. AUDIENCE: Consumers – Residential
Homeowners
See IRS form 5695 http://www.irs.gov/pub/irs-pdf/f5695.pdf:
What’s New for 2008 - Non-business energy property credit expired. You cannot take the non-business energy
property credit for property placed in service in 2008. What’s New for 2009 - Non-business energy property credit
available. The non-business energy property credit will be available for property placed in service in 2009. The credit is
available for items such as high-efficiency heating and cooling systems, water heaters, windows, doors, and insulation. The
amount of the credit will be limited by the amount of any non-business energy property credit you took in 2006 or 2007.
Taxpayers should consult their tax professional or accountant for how the PowerwoRx e3 can qualify for the Tax Credit and
how much of the purchase price and installation costs apply. Continental Power makes no claim regarding an individual’s ability to receive a tax credit.
22. Can PowerwoRx e3 be mounted on the outside of the building?
The standard PowerwoRx e3 case is a NEMA 1 and therefore cannot be mounted outdoors or where exposed to moisture.
For exterior mounting order the PowerwoRx mounted in a NEMA 3 enclosure
23. Will PowerwoRx e3 affect X10 lighting control systems, or Telephone or TV signals that are sent over the AC line?
Considering the Harmonic and Noise Filtration technology used in the e3, this is a good question. Continental Power
Corporation has found that the harmonic filtration capability of the e3 WILL cancel out the X10 and other control signals
generated to communicate over the AC line. Other systems include UPB (Universal Powerline Bus), CEBUS, Insteon and
LONWORKS to name a few. Consequently PowerwoRx e3 should not be used in buildings where the AC line is being used to
transmit lighting control, telephone, TV or any other signal. A special PowerwoRx may be available in the future which has
the harmonic filtration removed. For now, contact customer support and request a custom unit with the filters removed.
Note that most newer control systems are no longer using powerline data transmission. This includes Insteon although they
still provide downward compatibility with X10 if necessary. The PowerwoRx will have no impact on radio frequency (RF)
control signals.
24. How can the PowerwoRx e3 provide the exact amount of capacitance to correct the Power Factor in every home?
Understanding that the ideal power factor is 1, and that poor power factor makes for an inefficient electrical distribution
system which translates into higher kVA as well as higher KWh. A common question is “how can this device work in every
home”? Some companies promote having an electrician come out to a home, measure power factor and then create a
custom unit designed for that home. There are several reasons such a process is not recommended:
1. The power factor will vary depending upon what appliances are running at any given time. If the goal is to measure
power factor, what appliances should be turned on?
2. Years of experience has shown that the configuration of PowerwoRx provides the optimum solution for the majority
of homes. To produce a custom solution adds significant cost and provides little if any payback.
3. Some are concerned that adding too much capacitance will put the home into a lead condition (where the current
waveform will lead the voltage waveform). Again, this will be dependent upon what appliances are running at any
given time.
25. What meter can be used to verify Power Factor and the other parameters required to evaluate my electrical system?
There are dozens of meters on the market. At the high end are meters like the Fluke model 435 that sells for $7000+.
Continental Power recommends a simple and basic Power Clamp Meter manufactured by Extech (P/N 380976) that includes
the ability to measure Power Factor. This meter is available several on-line merchants including
http://www.tequipment.net/Extech380976.html. Continental Power also recommends the Fluke 1735. For more
information go to: http://www.transcat.com/Catalog/ and search on the Fluke model 1735
26. Some customers using other “Energy Savings Devices” or basic capacitors in a box of which there are a dozen
products like this, have not experienced any energy savings. Does this mean we will not see any energy savings with the PowerwoRx e3?
Typical “Energy Savings Devices” on the market contain capacitors which place 30 micro farads on each phase (60 micro
farads total), potentially over correcting the system in many cases. The PowerwoRx e3 only has 30 micro farads total, so
overcorrecting will be rare with the PowerwoRx e3. The advantage of the PowerwoRx e3 is the "synergy" of the 3 elements;
surge and spike protection, harmonic filtering, and energy savings. These synergies are vital together. The biggest difference
between the other devices and the PowerwoRx e3 is line conditioning. By cleaning up the power the motors are more
efficient and not as wasteful. Competitor’s products overcorrect and in some cases no savings are realized. In these cases
installing a PowerwoRx resolved the problem. In no cases have we experienced a customer’s electric bill going up due to the
addition of capacitance. There have been instances where a customer was saving energy and then added a swimming pool
and another unit was added to compensate, but never the other way around.
Here is an excerpt from a university about using capacitors to increase power factor:
"Adding too much capacitance can push the system from “lagging” to “leading”; for example, adding too much capacitance
may change the power factor from 95% lagging to 95% leading. Although leading power factor does not harm equipment,
purchasing excess capacitors is expensive and serves no useful purpose. In addition, some meters may read a leading 95%
power factor as 95% lagging. If so, you would not get credit for the power factor correction from 95% to 100%. (Other
utility meters would read a power factor of 95% leading as 100%). Because of these reasons, we recommend a
conservative approach to power factor correction in which we never overcorrect the power factor past 100%".
27. Does PowerwoRx e3 protect me from all Surges and Spikes?
PowerwoRx e3 provides protection from Surges and Spikes coming in on the main power line, as well as internal threats such
as those originating on a branch circuit. Although electrical appliances and electronics in the branch circuit where the surge
or spike originated are exposed, once it reaches the main power panel where the PowerwoRx e3 is connected the surge or
spike will be arrested. Considering there are typically 15-20 branch circuits in a typical home, the risk exposure is minimal.
It should be understood there are two additional paths which a surge or spike can enter the home from which are NOT
protected by the PowerwoRx e3. These two paths are your cable service and your phone service. The only way to protect a
“surge back feed” through cable and phone wiring is to provide surge protection on all three sources of entry that includes
your electrical system, cable system and phone system. Cable and Phone surge suppressors are available from most electrical suppliers.
28. What causes powerline surges?
Surges can be classified as external and internal. External surges are generally more severe than internal surges while
internal surges generally occur more frequently (about 80% of all surges are internal). External surges are frequently caused
by storms and normal power company switching operations. Internal surges occur when equipment within the building is cycling on and off.
29. How often do surges occur?
Very large surges occur infrequently (from a few times a year in medium exposure areas to 40 times a year in high exposure
areas) since they are mainly storm induced (lightning and temporary interruptions due to storm damage), but surges over 1000 volts may occur many times a day since they are caused by normal equipment operation.
30. Can PowerwoRx e3 help resolve issues with interruptions in electricity?
PowerwoRx is not a solution for brownouts or power interruptions which last more than a few milliseconds. Many customers
complain of these types of power issues and the only solution for insuring an uninterrupted supply of electricity is a UPS, or
uninterruptable power supply. These devises are much like what is used to power computers, just much bigger. The
PowerwoRx would be able to help resolve issues with harmonics, noise, surges or spikes, but the PowerwoRx cannot help
with power dropouts that last more than 2 cycles or 1/30th of a second.
It should be noted that the major risk in a power dropout or brownout condition is when the power comes back on. At the
point at which power is restored, all inductive loads come on at the same time, creating damaging power spikes and distortion (noise and harmonics). The PowerwoRx provides protection for this damaging condition.
31. How can PowerwoRx e3 help reduce surges and spikes if it is merely connected to the panel and only has 12 gauge wiring?
The surge & spike protection is accomplished by a device called an MOV (Metal Oxide Varistor). When the voltage rises
significantly above the rated voltage (+20%), the MOV turns on and the voltage is shunted to ground, insuring the system
doesn’t see the spike or surge. By definition this is considered a spike arrestor. The other components in the PowerwoRx,
the harmonic filters and electrolytic capacitors act as suppressors by capturing the small surges and spikes that come down
the line.
Confusion often occurs because logic would say that the unit should be connected in series like a fuse or breaker, so when
there is a surge or spike the PowerwoRx would open the line. This line of thinking is logical but that is not how this device or
others like it operate.
Regarding the 12 gauge wiring, logic would also say that no wire that small could handle 40,000 amps (max rating of the
PowerwoRx). What needs to be understood is the rating is based upon a very short spike, literally milliseconds in length
which is occurs in a lightning strike. The product cannot handle a sustained over voltage but such occurrences are extremely
uncommon.
32. Can PowerwoRx e3 be used with a back-up power generator?
Back-up power generators are becoming more and more common in home applications as well as commercial, often run off
propane or natural gas as a protection for power outages. PowerwoRx is an excellent addition to a system which
incorporates a back-up generator for several reasons:
‐ In the switchover process which is typically automatic, as the generator comes on line and the relay which connects
the generator to the main panel is closed, typically a spike in power is induced. The PowerwoRx e3 will clamp this
spike, thereby protecting appliances and electronics.
‐ Power supplied by back-up generators is typically not clean – meaning the noise and harmonic content is high. The
PowerwoRx e3 will reduce the overall noise and harmonics.
‐ Back-up generators are typically not sized to run all appliances. In some instances loads will exceed the rated
output. PowerwoRx reduces KVA demand from the generator by supplying the reactive power to inductive loads.
This means that a customer can realize additional capacity from their generator they would not have had without
PowerwoRx e3.
‐ PowerwoRx will help to reduce I2R losses when powering inductive loads.
One note of caution: Most back-up generators are connected to a sub panel which powers a select group of circuits so as to
not overload the generator. The installing electrician must take this into account. If the PowerwoRx e3 is placed on the
main panel and a contactor to isolate a sub panel for back-up power loads is used, the PowerwoRx e3 will not be connected
when the generator is engaged.
In no way will there be any detrimental effects to either the PowerwoRx e3 or the generator. We highly recommend the PowerwoRx e3 for emergency backup generator applications.
33. Can PowerwoRx e3 be used with Solar Panel/Wind Turbine installations and/or Reverse Metering?
PowerwoRx e3 is an excellent addition to any solar panel/wind turbine installation regardless of the configuration including
the use of Reverse Metering (where electricity is fed onto the grid by the user). Some common configurations are:
‐ Solar or wind is used to supplement the systems energy needs
‐ Solar or wind is connected to the grid via a bi-directional electric meter (Reverse Metering)
‐ The system is off grid and relies on 100% solar energy for all the energy needs
All three of the PowerwoRx technologies benefit a system which incorporates solar and wind energy generation:
‐ Surges & spikes are more frequently internally generated than external. Solar Power Center protection is
accomplished by a device called an MOV (Metal Oxide Varistor). When the voltage rises the PowerwoRx prevents the
spike from potentially damaging the expensive electronics including the Inverter.
‐ Harmonics are more prevalent in a solar generated power system due to the nature of how the AC waveform is
created by the Inverter. These Harmonics waste electricity, are damaging to appliances and electronics.
PowerwoRx significantly reduces Harmonics and Noise in the system
‐ Improved Power Factor translates into reduced I2R losses, increasing system capacity and reducing energy use
34. If the PowerwoRx is hit with such a large spike that it sacrifices itself, will the electricity still be on? Is the home still protected?
The PowerwoRx is connected in parallel (not like a fuse which is in series) so in no case will the supply of electricity to the
home be affected. If the home is hit with a surge & spike of great magnitude like what would occur from a lightning strike in
the area, and the PowerwoRx e3 sacrifices itself, the result is the PowerwoRx will no longer be operational. This is indicated
by:
1. One or both lights will no longer be lit.
2. There is typically a strong smell of a damaged electrical device. This is normal and indicates the unit has sacrificed
itself in order to protect your homes electronics and appliances.
In either case it is just as if the PowerwoRx had been disconnected from the panel, meaning the home will no longer be
completely protected and a replacement unit should be ordered immediately. Remember, PowerwoRx carries a 10-year
warranty, and the only limitation is the product must be installed by a licensed qualified electrician.
35. What happens if a lightning spike comes into a building through a window air conditioner or some path other than the electrical line?
Surges and spikes often come through paths other than the main incoming electrical line. The PowerwoRx is effective at
arresting these surges and spikes but the owner must realize that the surge or spike must reach the PowerwoRx. This
means that any electrical appliances or devices on the branch circuit where the surge or spike originates will potentially be
damaged since they are located before the PowerwoRx. For this reason point-of-use surge suppressors should be incorporated on very costly or sensitive electronics.
36. When a Demo Case is being used in a home with PowerwoRx Installed, why does the meter still show the same as before the PowerwoRx was installed in the home?
The PowerwoRx Demonstration Case is an excellent way to show exactly what the PowerwoRx is doing with regards to a
motor load. When first turning on the demo case we see that the current coming to the case (what we call the SUPPLY side)
is the same as what is going to the motor (LOAD side). Once the PowerwoRx in the case is turned on, the current coming
into the case (supply side) drops, yet the current going to the motor (load side) is the same. This is because on every cycle
of the AC waveform, literally 60 times per second, the PowerwoRx is storing reactive current and supplying it to the motor
when it needs it. In essence the PowerwoRx is recycling energy which otherwise would have been wasted. When then the
PowerwoRx in the demo case was turned off, the PowerwoRx in the home was storing this reactive energy and supplying it
back to the motor. Since the motor always received the current necessary to run, approximately 1.2A, the meters don’t
show any signs of a PowerwoRx in the home. A person would have to go back to the 200A electric panel and take an
inductive current meter around the incoming power line at the top of the panel to see the effects of the PowerwoRx mounted
in the home. This is a typical method to show that the PowerwoRx is not only working, but is having a very positive effect.
But when the PowerwoRx is turned on in the demo case, now the PowerwoRx closest to the load takes over the
responsibility to store and supply (recycle) the otherwise wasted reactive current, which is why we see a drop in the current
in the demo case. Even if a home 5 PowerwoRx installed it would be the same, because the PowerwoRx in the case will always be the closest and therefore it will always be the device to recycle the current.
37. The electrician who installed our PowerwoRx tested the electrical system and said the PowerwoRx is making no difference in the current being used. How can I verify the PowerwoRx is operating?
Adding capacitance will always change the amount of current coming into the electrical panel as long as there is at least one
inductive load turned on. With inductive loads activated, the Power Factor will always change and there is never a case
where the amount of current being drawn from the utility or generator will stay the same.
The confusion is typically where the measurements are made. A common mistake is placing the clamp meter around the
wires going to a load like the Heat Pump. As the previous question details, the current on the load side will always be the
same.
We suggest the installer verify PowerwoRx is properly operating. By reading the current being drawn on either L1 or L2, and
then switching the PowerwoRx on and off will show a difference in current. The percentage difference between current draw
with PowerwoRx on and PowerwoRx off is dependent on initial Power Factor and the number of inductive loads.
38. How to determine if the PowerwoRx e-3 unit is working properly?
Using a typical current clamp meter measure the current going to the RED and BLACK wires on the PowerwoRx unit. An
installed and operational PowerwoRx e3 unit should "draw" (but not consume) approximately 2.75 amps. Another way to
show proper operation is using a Power Factor meter on the lines feeding the panel which the unit is installed. With
inductive loads connected to the panel and running, turn the units breaker on and then off. You will see the overall current
drop with the unit on due to a reduction in reactive current. You will also see the Power Factor (PF) increase with the unit on
and decrease with the unit off. Be aware that if little or no inductive loads are operating when doing this test, the meter
may show what appears to be a decrease in Power Factor. If you look closely at the meter, you will see that the Power
Factor display is showing that the PF went from lagging to leading. We suggest turning on some inductive loads so the PF
stays lagging but shows an increase.
It is important to remember that Power Factor measurements are a “snapshot” in time. On a residence, don’t be looking for
the PF to go from 78% to 96%. The PowerwoRx e3 has a fixed amount of capacitance based upon average consumption for
a typical 200A residential application. From studies of many homes, we know the PowerwoRx e3 will raise the average PF
to approximately 95%. Some electricians have voiced concern that during their measurements, the Power Factor rose up
only 5 or 10% and is still below 90%. Again, this is a snapshot, and in most cases the measurement was taken with the
majority of inductive loads turned on. Our goal when using a Current Meter/Power Factor Meter to validate that the unit is
working and to show the customer that when the unit turns on the current drops and Power Factor goes up. The amount of decrease/increase is inconsequential for the purpose of the test.
39. What does the number on the e-CoMeter indicate regarding noise and harmonics?
The e-CoMeter has been developed by Continental Power to show the overall harmonic and noise level on the AC line. The
actual reading of 0-1999 does not correspond to any specific value such as volts or frequency, but should be considered a
relative level of harmonics and noise. By taking an initial reading, the distributor can show the building owner or occupant
the current reading - the lower the number, the better power quality. A good demonstration to the customer is to show
what the current level is and then plug in a PowerwoRx e3 with a standard ‘B’ plug connected into the same outlet. You will
typically see a reduction of 60-90%. If the meter reads 2---, or shows no numbers, the meter is in an “Over Range”
condition, meaning the actual value is above the maximum displayable value of 1999. In these cases the distributor should
point out to the customer that the Noise and Harmonics are exceptionally high and action should be taken to protect their electronics and appliances.
