AMF Panel
Watches the mains, starts the set when it fails, transfers the load, and puts it all back when the mains returns — with no one in the building.

Specifying this panel
The interlock between the mains and generator breakers is the part that matters. It is both electrical and mechanical, because an electrical interlock alone can be defeated by a welded contact — and paralleling a set onto a live mains destroys it.
The cooling-down run is not optional. Cutting a turbocharged set the instant the mains returns cooks the bearings; the panel holds it running off-load first.
