    Multi Location Interlock or Lockout

    Hi All,
    I have a situation where my main breaker is on the outside of my house and the main panel is in the cellar. The panel does not have a main breaker and can not be converted from a main lug. I was wondering if there is a device that works like a lockout/tagout but you physically need to take a part/piece or key from one location to another to activate/deactivate the other breaker.

    In this manner it is impossible to have both on at the same time. I realize I can lock a key in one panel that opens the other but its really not that safe.

    Thanks in advance.
    Sean

    Thanks for you help Larry, but Im trying to make if "fool proof". Maybe I should explain what im trying to do.

    I would like to back feed the panel from my generator and as the main breaker is in a remote location I cant use a physical interlock. Im trying to avoid swapping the panel for one with a main breaker.

    I travel alot so it would be great if my wife can do the swap over.

    Maybe I'm over thinking it, but I dont want to kill anyone.

    Thanks

    DPDT switch
    I don't know how big your service is. This one is 200A.
    But I suspect you don't want one of these eihter

    They are called a "trapped key interlock". Kirk Key and Castel are the only two I seen. There are likely others. I've never seen one for a residential panel.

    I suspect the price will make a 200A DPDT switch look cheap.

    Which one?
    DP switch?
    Trapped Key Interlock? If this one, I'll be curious as to the price.

    Which is a real possibility when it comes to back up generators. A proper transfer switch installed by a qualified electrician is what you need. And with that...
