So I already have a dedicated 220V outlet in the garage. My dad had it put in for a arc welder but never bought one. It's a 10-30p on a 30A breaker like this. I want to upgrade it to a 14-50p since most EVSE's have this plug on them already. i do not want to hard wire it. I know i will have to upgrade the breaker to a 50A. pic of the current breaker attached. Can I swap it out to 2 50A paired breakers next to each other? please tell me i dont have to swap out the wiring. Or should i just get an electrician?
