    OK to add a 50 AMP breaker in this panel?

    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...

    Can you explain to breaker info to me?

    I am buying a house and it was built in 1949. Is there anyway I can tell if it has tube wiring without opening up the walls? Is there anything else I need to watch out for with a home built in 1949? Also can anyone explain these 2 photos to me? Does any of it explain if there is tube wiring?
