    DPDT switching branch circuit from one breaker to another?

    I’m planning a 240V welder circuit in a detached garage with a 100A sub panel. For the 160A or 180A output welders I’m looking at, the conductor can be #10, and a 30A breaker is probably OK, but a 40 would help the duty cycle. Conductor must handle welder's 1eff rating, breaker can be up to...
