    The primary OCPD is allowed to protect the secondary. Protecting the wires fed from the secondary is a seperate issue, yes?

    I think that his idea is that if he has a separate Ufer or 8' ground rod somewhere, but that ground is not connected to a panel anywhere, then the wires connecting from each bollard to that ground...

    Again, it is not the NEC, but POCO may well have their own standards for location and protection of their meter with which you have to comply before they will supply power.

    How about you use a 4AWG wire to connect the bollard to itself :), since its mounting serves as a concrete encased electrode, just not one large enough to be used for the sole GE of a building.

    I would instead say that you do not generate electrical charges. You can generate potential differences that drive current though, and I am perfectly happy to call that generating electrical energy,...

    The text tells us that the breaker was likely not the direct cause of the arc flash. Instead the breaker did not actually open all poles of the circuit when operated manually (which can happen with...

    If both NRTL's test to the same standard, it is hard for me to see the justification for making the approval conditional on using the same NRTL for all of the component equipment. That may not stop...

    With either exactly balanced or completely unbalanced, the neutral current will be equal to the highest phase current, not less than.

    First off, why are you even thinking of using a three phase transformer when you will have only a single phase load?
    That will not give you any better balanced load on your primary than using a...

    The OP stated four customer-supplied heaters, as in one store. No mention was ever made of four customers IMHO.

    The first answers addressed the load of each heater, figuring that someone would go...

    You are welcome. The free trip feature and the trip to center position combine to make it unlikely that the handle tie will allow one breaker to trip the other.

    If all of the current was on the line side of the breaker, it will not be able to trip the breaker....

    A two pole (240V) GFCI breaker can work just fine with the shared neutral of a properly wired MWBC. It just runs three wires through the current transformer instead of only two.

    You can never be too careful with garbage trucks! How are you going to bring the wires back up? Between the carports?
    Make sure that it is well protected from stray traffic too.

    Some do specify Class B GFCI. And although that does not replace required Class A GFCI for a circuit, it probably detects more potential fire producing faults than the whole AFCI section. :)
