What's the switch called that you use to cut a circuit over from street

And do they come in a little 15- or 20-amp version?

I just lost most of today's opportunity to work to a power outage (big
windstorm today), and spent my down-time buying a generator. I can just
toss an extension cord through the window of my office to the generator,
but it'd be nice to connect it to my office plugs instead.
It is known as a "Transfer Switch"
