How to Wire an Outlet (Project Tutorial) - Bob Vila
It only takes a minute to sign up. Connect and share knowledge within a single location that is structured and easy to search. I have an electric dryer with a 30 amp circuit running to it. If I had a male-male plug to run from a portable generator to this outlet, would it be safe to run essential appliances water pump, refridgerator, sump pump, etc during a power outage as long as I tuned off the main breaker and the total draw was less than 30 amps? You MUST use some form of transfer switch or interlock, along with the proper male inlet. Also, a male-to-male cord is called a "suicide cord" for a reason. The transfer switch and interlock mechanism is essential for the safety of both you and for the utility folks that may be working on downed utility lines.
A portable generator is a convenient way to safely generate your own power when the grid goes down due to either natural or man-made causes. Plan what you want to power and how you will use the generator to power those loads. Size Matters Size the generator correctly so that it meets the electrical loads you intend to power with some excess capacity built in. This can damage something as big as a well pump or as small as a computer.
A generator is a core component to many people's emergency preparedness plans. Maybe you have a cool charcoal powered or a multi-fuel generator. However many fail to think through how exactly they will power the items they want to run when the grid is down.
