Electric Saver

Has anyone used a product called an electric saver by saferwholesale.com? It claims that you can save about 10-50%? I found it on ebay while looking for wind turbines.

Looks a bit like this http://www.power-save.com/1200.html

I installed one of these and can't say that I saw much difference. Our usage fluctuates though so kinda hard to track.

There are some local vendors with good prices here, I compared to bringing in items and with shipment charges I would save money buying locally. Wind Turbines and Solar panels in my price comparisons.

google "power save scam" .....

It's bogus. At best, the device consists of a capacitor. The clamp meter does not measure power, it measures current; you need a wattmeter to convince anyone who understands this stuff. If you're pulling down the current that much, you've got a real power-factor problem, but I suspect bogusity. The weighing part was particularly amusing.

Don't bother with these things. None of them do anything, and if they did, they'd be incorporated into appliances already. You've already got capacitors in your various machines and light fixtures to correct the power factor, and the 'filtering' does nothing at all for your electric bill.

The best thing to do is to learn to read your electric meter and learn the power consumption of each of your appliances. You may find, for example, that the electric heater someone uses to warm their feet takes more power than all of your tools.

Volts X Amps=Watts or,with 2 known factors you can calculate the third(example watts divided by amps,= volts etc).
So, there really is no way to cheat the formula (you can add devices that allow a rush of voltage & or current such as a motor starter)<<But this wont chane your WAPA bill!

Some folks think (or are told by "electrical management"companies), switching to 240, they will only use 1/2 the power,when in fact,it`s 1/2 the current(amps), but twice the voltage so it`s exactly the same watts!

240 has many advantages,such as the wire size can be smaller,it works better on generators as the 2 hot legs are balanced, & uses all 4poles instead of 2 which loads/unloads those two poles.
One disadvantage is the increased possibility of electric shock.

For boaters traveling between Euro & US power,there are several differences such as frequency, no possible 120 from the Euro neutral,& so on.
