    The CT in the meter, or the current coil in a series connected meter, will always detect current, but they will include the timing information as well, so that the meter can record the vector product...

    If the 100A subpanel has a 100A main breaker it would be OK, yes?
    The "directly from to" statement is unclear. I do not Dee it as saying from a 200 main (service disconnect?) to a 200 main in...

    There will be no inductive heating, since that only occurs as the result of a changing magnetic field from AC current flowing through the wire. And only if the EMT or IMT or rigid is ferromagnetic...

    I would see it as more likely that an unloaded 200A wire would carry more heat away from a fully loaded or overloaded 100A wire, reducing the terminal temperature.
    The combination of fully loaded...

    If a woodchuck could chuck all the wood he would chuck,
    how much wood would a woodchuck chuck?

    He'd chuck all the wood that a woodchuck could,
    if a woodchuck could chuck wood.

    There are timers that will turn the fan on with a light and then keep it on for an adjustable time delay after the light is turned off.

    Yes, I meant line to neutral voltages.
    The problem is that the common meter measures both line currents and assumes that each current corresponds to one half of the line to line voltage. The...

    The NEC does not recognize the running (constant diameter) threads of the connector as a fit for the tapered pipe threads of the LB.
    Unless it has somehow been listed for that specific use.

    I think that it was a reference to a metallic raceway connection in addition to a ground/neutral bond at each end?

    Although I don't think anything in the OP implied bonding at each end, except...

    Every water feature that I have seen uses a continuously running pump. But probably not very large.

    In particular, (1) requires a GEC connection next to the service disconnect, and if my interpretation is correct each shed has its own service disconnect.

    In particular, I suspect they are worried about double tapping lugs or otherwise doing stupid things, but instead of inspecting for that they have gone all formal on you.

    I am confused. It sounds like this is supplied from the same POCO service, which is a grounded wye. So the delta circuit that they run from that point outward is not going to be either ungrounded or...

    That would make the shed wiring service conductors, which...

    Well, the instantaneous peak power every half cycle will be twice the average power, even for a constant resistive load, so you technically need to specify some time period.
