Murray MH-T Circuit Breaker (want to add another breaker)

Hi there, I want to add an additional 15 amp breaker in my RV, and the panel has 1 spare double spot. The existing breakers say Murray MH-T on them. This trailer is from the US, and was shipped to Canada. I'm having a hard time searching for this Murray MH-T breaker online from any big box stores.

Is the breaker "type" MH-T? In other words are there other manufacturers that will make a compatible breaker?

    Don't worry about what the existing breakers are. Look at what the load panel says are compatible. For instance, for the very common WFCO 8900 series:

    Model/Cat. No./Type
    Cutler Hammer Type BR and C, Type BRD BD and A
    Thomas Betts Type TB and TBBD
    ITE/Siemens Type QP or QT
    Square DType HOM and HOMT
    Murray Type MH-T or MP-T


    AH...I see! Got it now...my panel is WFCO 8900 like you said, so it will work with those models. Much easier, as HD does carry some of those. Thanks!

    type in 15/15 on the ebay search box
