    Correct fuse type and size
    I purchased a Cutler Hammer DPF222RP service disconnect for my AC unit. This is a 1-Phase 2-Wire, 240volt 60amp unit. I installed 2 35 amp Rk style fuses and one of them blows when my compressor tries to kick on. My question is should I have installed 60amp fuses?

    Without knowing the exact specs of the A/C unit it is impossible to say.

    I don't think it is.
    Could you mean LRA?
