    Disconnect Clearance

    Do you need to allow for the working space in 110.26 for a non fused safety switch?

    Specifically for a disconnect for an AC drycooler?
    This is a 480 volt nonfused disconnect. (not a disco)
    This would be a condition 2 that would require 3'6" of clearance.

    I believe that it needs the proper clearance and headroom.

    I feel that it is likely to be examined while energized.

    If that is so, then yes.

    I agree with Volta, but what do you mean by "(not a disco)" when you're referring to a disconnect?

    I mean a disconnect.

    A disco to me needs a mirrored silver ball.
    The term is so residential.

    Well yes .

    Would you need a clearance in front of a transformer ?

    No fuses in it ?


    But you check voltage to service it or you might open it up to test or check lugs or grounding connections if you had a problem so yes to me anything electrical needs space in front .

    Ive got a question how about a 4 square box ?
