    Do not just assume that the meter is high input impedance just because it is digital.
    If it has a low input impedance (say 1000 ohms), then .32V DC corresponds to .32mA, which is pretty hard to...

    That is perfectly easy: Send your apprentice upstairs as many times as necessary. That way you do not have to go upstairs even once yourself.

    My immediate mental image on reading the title of this thread was of someone so frustrated by an AFCI breaker that they put two bullets through it.

    There are two potential sources of heating in the metal. One is eddy currents, whose source is not particularly clear and which would be more significant in non-ferrous cases. I do not consider those...

    You have 20 ranges to spread over three phases.
    Naive arithmetic tells you that is only 6.66 ranges per phase.
    Common sense tells you to split them up 7,7,6.
    If you put all 20 on one phase you...

    The practical difference is that in one case the contacts are held together by spring force and in the other they are held together by the coil/armature force. Makes a difference for weak coil drive.

    From what I have heard about the situation in Scandanavia, the first fault is simply never dealt with. Any maintenance waits for the second fault to force the issue.

    I would not say that it was necessarily the same thing. It is the same as what we currently suspect is the problem with the lighting circuit.

    With "the meter pulled", there should be no load current in the service neutral and so no effect from rebounding between GES and neutral on the customer side.
