This is a replacement box that I had to purchase due to the fact the first one that I bought and installed It didn't work right out of the box had some sort of internal issues for grounding issues I'm not sure My installer of 35 years installed it properly and correctly switches wouldn't work. This is the second unit we'll see if it works better than the first one
