I am attaching a link. I have my doubts about this product. It is suppose to correct the pf at your home caused by the AC, fridge, (motors) etc. I can see the theory but not the application because it doesn't seem to me that true power oppose to apparent would be that big of a "factor" in a home. I could be wrong.
