    Zinsco Electrical Panel question

    Could that have been the main when power was first installed and then when power was upgraded (there clearly is more than 70 amps of power being used thru that entire panel), leaving that main only controlling the few original breakers?

    Zinsco Electrical Panel question

    In the panel foto below, there's a 70 amp breaker at the top right with no specific assigned circuit. It had been referred to as a disconnect, and had been blowing occasionally until the wires to it were "rerouted". What might have been the purpose of this 70 amp breaker?
