    Isolated, in this context ONLY means isolated back to the single point where the EGC wires and the service or SDS neutral are bonded.

    What it gives you is a ground reference to that specific...

    Leaving said for the moment the question of whether AFCIs save lives (and whether the GFCI component of AFCIs that have them) save lives, there is no way that the AFCI component which would detect...

    N is the fully loaded number of bulbs for the ballast.
    N-1 is leaving out one bulb, like 3 out of 4.
    N-2 would be 1 out of 3 or 2 out of 4.

    Since it is a backwards RU, it is a recognized component only. That does leave some concern in installing it into a listed fixture in the field.
    But not any more so than retrofitting ballast...

    You can not have multiple feeders to the garage, but I do not see a prohibition against multiple branches. Although I do agree that the requirements for a local ground as well as EGCs from the main...

    Any meter installed at 6.5' to the top will automatically bevless than 6.5' to the bottom. So no problem. It just allows you to mount it even higher than you used to.

    The most important difference about the starter winding is that it is mechanically offset somewhere close to 90 degrees of rotation from the run winding.
    That means that if you drive out of phase...

    Make that "rarely low enough" and I will agree with you.
    And it is mostly the skin resistance that counts.

    100% definitely not!
    Line voltage drop aside, the closer the series resistance gets to zero the closer the series current gets to the parallel case current. But it is never greater.

    OK, but if you reread your words carefully you should see that you are implying that if the load resistance is low enough the series result will be *worse* than the parallel result.

    And if the terminal block is internal to the equipment and not used for connecting field wiring, then the NEC might not have much to say about it in the first place.

    Whether or not you agree with what the tech is proposing, the NEC prohibits it for valid safety reasons and that should be the end of it.

    This says exactly one thing to me: the two neutrals that you mentioned are not in fact connected together, even at the panel bus.

    The reason could be that one of the neutral wires is open, or...

    Well, it is a little simplistic, but the biggest physical change is probably the inclusion of rejection tabs in some of the positions. :angel:
