What's the box that's marked Power Save or Power-Saver next to the electric panel do?

Friday, January 25, 2019

There are multiple products with similar souding names that claim to produce power savings, and the subsequent reduction in your electric bill, by using capacitors to alter the power factor of the electricity being consumed in your home. "Power factor correction" is further claimed to extend the life of electrical devices, help electrical motors run more efficiently, save light bulbs and eliminate static interference. 

    More than a few electrical engineering professionals have called the claims dubious, at best, for residential electrical systems. The example shown above is a PowerSave ABET2201.
