Not in any power panel that I have seen recently.




I think he meant that the bus was fed through the main breaker, which IS
fed by a wire, usually coming from the meter base.

But, to make a meaningful measurement using that wire he'd have to
switch off ALL the other breakers on that feed's side of the panel. Not
a very practical solution, is it? G
