    Doesn't the second ground rod need to be bonded to the first via a conductor in addition to the EGC connecting the two panels and external to the conduit containing the feeder?

    Of course it is; I don't believe anyone has said otherwise. Measuring that Watt in the real world involves averaging some quantity of energy over a time interval, though.

    I think you (the collective you) are twisting on the point where calculus applies. For example, any a line in X-Y space has a slope for every value of x, but it cannot be determined from that point...

    Agreed on all points. I have run into this exact problem, and a supply side tap on the input busbars of the MDP main breaker was the only viable solution. That, or add another section to the MDP, but...

    If it's 100kW at 480VAC three phase, it looks to me like it could just barely fit into a 150A OCPD. (100,000)(1.25)/(480)(sqrt3) = 150.35A. About 73kW is the most that would fit into a 110A OCPD at...

    This is a silly argument, IMO. In AC power the fact that in theoretical terms a Watt is an instantaneous quantity is a useless distinction; 120 times a second the voltage crosses zero so the voltage...

    I could be away on vacation when the GFCI trips; sometimes a heavy rain will do it. No, thanks. I'll just leave the fridge plugged into a regular outlet if it's all the same to you.

    My fridge is not on the single GFCI circuit in my home. I wouldn't want it to be; the GFCI is sometimes tripped for days and I don't know it.

    So Watt, I mean so what? It's a distinction without a difference. My point was that some POCO's charge not only a rate per kWh, but add a peak demand charge based on kW. It makes no difference if...

    My question as well. If you are landing on existing busbar perforations on the line side of the main breaker in the MDP, it isn't a field alteration according to all (three, I believe) the MDP...

    I have run into this several times, where we want to land on empty existing holes in the bus bars on the supply side of the main breaker of the MDP. The AHJ's wanted to get some documentation from...

    I am of course aware of that, but the language in some tariffs refers to kW rather than kWh. Just how many angels can dance on the head of that pin, anyway? :D

    Of course, but what some utilities are looking for is that peak rate of current flow. I have read tariffs that explicitly say that. Of course there really is no such thing as an instantaneous...

    Actually, in many places you get charged for both. In addition to the kWh charge for energy used there is a kW surcharge based on your peak demand.
