    The original PV wire was only 1000V. That is still better than the RHH stuff because there is no UL standard for a 1000V rating for that wire type.
    It was only later that PV wire rated at 2000V was...

    Are some of those wires EGCs?
    Are some shared neutrals for MWBCs?
    In both cases you will not count them for ampacity adjustment, but do need to count them for mechanical fill limits.

    And if the circuit is more than 20A, as it is likely to be, you do not have to worry about putting in a GFCI protecting the receptacle.

    It seems to me that he was trying to say that not taking any care about the raceway continuity just because you have pulled a wire EGC is hack work, and I am inclined to agree with that.

    I keep seeing comments, in the clip and elsewhere, that talk about inductive loads taking more current at a lower voltage.
    What is really happening is that constant power loads, whether they are...

    It might have something to do with AHJs enforcing local energy codes requiring a special socket. And therefore an LED replacement for CFL would have to use the same socket type.

    Strictly speaking, the choke effect could also happen if the source of the current in the EGC was some other circuit not in that raceway. Or, of course, lightning surge. :)

    At least some feel that line side PV disconnects are not part of the six handle limit at all, since they are technically not service disconnects.

    There are designs for cargo vessels that use wind power though. If fuel costs go high enough, the tradeoff of travel time for fuel economy becomes important.
