    Disconnects of any size generally have an over-center action and strong springs to actually snatch the contacts open quickly. Pull-outs would always be subject to the slowness of the person operating them. And they could stick part way out - that might get exciting. <g>

    I hear ya, but in the case outlined above, little chance of arc flash with blown fuses.
    I do a triple evac with nitro to remove non condensables.

    I'm with you. I actually go a good bit further with the concept - I wait to eventually fall out.

    Yes, I am joking (mostly )
    I hope you were joking. NEC 110.26(D) Illumination. Illumination SHALL be provided for all working spaces about service equipment, switchboards, panelboards or motor control centers installed indoors.

    The next time they rework this NEC thing - see if you can push for a rule stating:

    Intelligence and Understanding SHALL be provided for all working space about service equipment, switchboards, panel boards, or motor control centers installed indoors.

    That would be a nice addition.

    The NEC requires minimum space for service equipment and other electrical devices. Generally this is not followed in residential because of available space/laziness.
    "Intelligence and Understanding" is the same as "Common sense" since the latter no longer exists neither does the former.
    I refer to it as uncommon sense.
