Hi All,

I have a friend/customer (in that order) that is asking me for some input on the a capacitor setup device to be put on his 200 amp residential service. Anyone here have any experience or knowledge in these units.

Do they work??

Are they worth the expense??

Is there a savings??? Really???

Watch the video and comment please.

BTW I did notice that the motor did not have any load applied at the time of the test. Hmmmmmmmmm???

You can go here for the home page.

Thanks for the input.

I have been looking at these too. the only savings will be on motor loads. I have my doubts on that as the only large motors in my house are the frunace air handler and two condensing units and these already have run capacitors on them. Notice also that there is no capacitor on the motor in the demo.

There has been no independent study to show that this will make real savings to amount to anything. So my answer to your questions would be:

1.Are they worth the expense??.....NO

2. Is there a savings??? Really???....Not really

I've got a bridge in Brooklyn for sale, if you're interested.......

Ok, so if I understand it correctly it may be somewhat beneficial in a residential application if a majority of the load is due to motors that do not have run capacitors attached.

Motors in such devices as ceiling fans, exhaust fans, water pumps, will benefit somewhat but air handlers, HVAC compressors will NOT because most likely already have run capacitors.

Of course all resistive loads, such as lights, baseboard heat, stoves, will also NOT show any benefits.

Am I correct in my assessments???

Again thanks to all the reply.

BTW I heard that buying a bridge and putting a toll booth at both ends can be profitable if the fee is set correctly.

Pretty much right on.

You bet! This bridge is just dripping with money!

there was something like this many years ago for the fridge a plug in unit at the box stores did not last long on the shelves

We run a cabinet shop with cmc machines, edge banding machine, table saws etc... and we have and ecoQube ecoCI200 installed at our place that seems to be saving us an average of 20% or so a month. I know that they also make residential cap banks too. I believe their website is ecoqube.net. Not too sure how they work on residential, but many say it helps.

Agreed on lots of motor loads it will help. 20% is a good number.

As Celtic suggested go to the link below. It will hopefully answer your question on residential. Just subsitute ecoqube.net for power saver as you read.

Have a good day.

This garbage again?

Same exhaust, different car.

No, they do not. A capacitor is useful for an appliance such as a microwave in order to improve power factor so that it can maximize the amount of energy it can draw from a 15A circuit. The same microwave without the corrective capacitor can be put on a 30A circuit and it would draw more current at lower power factor, but the energy consumption would be the same and it won't make a difference in cost under residential billing.

Oh, and putting that gimmick garbage is probably a code violation too. Is it even UL/CSA approved?


Step 1.) Call the utility that provides service(s) to premise in question and ask if there is a cost related to demand or power factor. If the answer is no, then move on. If you're not a three-phase customer, then the answer is quite likely "no".

Step 2.) For a machine shop with demand and power factor fees, spinning wheels in the air with a synchronous motor is useful for regulating power factor.

Utilities have always used usage time based billing for major customers, but are doing this either mandatory or optional for residential customers in some area too. Ask them if there is such a program available. No energy is "saved", however under time adjusted billing plan, kWh rate is reduced during off-peak hours, so using a huge water heater in conjunction with a timer or doing laundry on Sundays or off peak hours can save you $$$, but not kWh. For commercial users, running smelters and big motors during off-peak may provide savings.
