I worked for the power company for a long time but I was an operator in a power plant and not an electrician. I'm going to run a circuit for a Lincoln AC 225 welder in my garage that will be about a 20' run. The welder says it needs a 220V 50A input. I doubt it will ever pull that much current and if it did it would only be for short periods. I'm leaning toward a 50 amp breaker and #8 wire. What do you think?
