Wiring for 30/50 Amp
My shop is wired for 220 off a 30Amp breaker from the main box to a breaker box in my shop. The reason we didn't wire for 50Amp is because I hadn't used a heavy enough wire and didn't want to dig it up and start over. At the time I only needed 220 for my large compressor. It's about 30 feet away from the house.
I have a Lincon Arc Welder that will pull variable voltage, I normally use only 75 or less. The welder has a 125V plug on it.
What I want to know is what can I do to use the welder at the shop. I have a 50Amp outlet below the main box at the house, but don't want to weld everything over there or drag out my SUPER HD 50A extension cord.
Can I not wire a 50Amp receptacle from a 30Amp breaker? Or can I not use a 50Amp breaker on the 30Amp bars? (At the shop).
I'm probably not wording this correctly, but I hope you can understand what I'm trying to do
Any advice greatly appreciated.
