  1. Dave Rongey says:

    Hi Lisa,
    Replacement circuit breakers for the Zinsco brand are now available from the Sylvania brand. The Sylvania circuit breakers are available from your local hardware stores, or online at several outlets. Circuit breakers are best replaced by an electrician who can also inspect the panel to make sure the contact surface has not been damaged.
    NOTE: Work in electrical panels is not recommended for homeowners or individuals who are not certified or licensed electricians.

    I am trying to help my dad replace an old (dead) breaker it is a 20 amp double pole Magnatrip type RC 38. Does anyone know what we can replace that with that will fit in the same box?

  3. carol says:

    I need to find a breaker that will work in a Zinsco box but it needs to be a bolt in style, and all I can find out there is a used plug in. Does anyone have any suggestions?

  4. Steven weeck says:

    I have a Pannel that is a Magnetrip with Zinsco breakers in it. It has had more than one person working on it over the years and I have a little bit of a mess in it. I have removed some of the wires that went to knowhere. (220 just cut laying on top of the duckwork no caps) I have a question about the dbl breaker problem I have read about. Can you give me a better discription on them. Thank you

    Thanks Bob K

    I have a question, rather than a comment and it is also about the Zinsco Magnetrip. I just returned from a home inspection where the inspector showed me that the home I am looking to buy has this. He highly recommended having it inspected by an electrician and replaced. What I am finding online really does reinforce what he told me about them. Are you of the same opinion? The home I am looking to buy was built in ’46 and I don’t know exactly how old the box is.
