I *think* that's the correct term, but I'm not sure; it's the gizmo one would put between a small generator, your house and the utility connection, to cut in the generator and take you "off the grid" in case of a power outage.
Yes, I tried a Google search but didn't find anything useful. Have a customer who's asking about this. In fact, they mentioned the dreaded male-to-male plug that was ridiculed here not long ago. Thankfully I've talked them out of using *that*. (At least they knew that you've gotta disconnect from the utility lines if you connect a genset to your house.)
I'd like something basic, not too fancy, but smart enough to handle the whole connect/disconnect routine safely in case of an emergency. Say in the 5-10 KW range.
