My shop has a transfer switch since that's where the water pump is, powered by a Miller Bobcat 225NT* AC/DC welder 8000 KW gen, if power is needed in the house cords will fit the bill, the water heater & furnace are natural gas that do not require power, kitchen is all electric so that could be a problem.

*Was originally going to buy a 5 KW Honda, but listened to someones suggestion & bought the Miller welder for $400 more, got 3KW extra, & a portable welder as a bonus.
