Place the generator about 5 to 10 feet from your home to prevent carbon monoxide gas from the exhaust from entering the home.
Plug the extension cord into the outlet on the panel of the generator. Plug the other end into the dryer outlet.
Set the individual circuit breakers for your home's circuit breakers to "Off," with the exception of the circuits you want to power. Be sure that the circuit for your dryer's outlet is set to "On."
Turn on the generator to feed power into your home.
