How to hook up a 50 amp 220V AC service at the main power box. for a outlet.
Every service installation is unique in it's entirety, however some components are constants. This installation would require a 50 amp 2 pole breaker, 6awg wire, and other associated materials (conduit, boxes, etc.) to make it code compliant.
If you never did it before,i wouldn't recommend you playing with 50amps.People do get killed with that kind of amperage everyday.Have a pro do it.
