    IMO the old Table 310.15(B)(7) did not make prevision for ampacity adjustment. Common sense did but the NEC did not.

    I don't know why the manufacturers did that. It is a PITA. All they have to do is lower the heat strip a tad. I think what happened was they increased the fans on the units-- that's my guess.

    You need to know the load of the heater circuits-- Is the panel single phase or 3 phase? The 125% comes into play for each branch circuit that has heat.

    For example a 1000 watt heater would...

    Also the calculated load must be 55 amps or less. I have seen many supplemental heat units where the load is 56 or 57 amps.. I hate it because it then requires a #4.:thumbsdown:

    Yes, but for some reason I don't like the idea of a double duty equipment grounding conductor and grounding electrode conductor. Perhaps if rods did more than what they do I would definitely be...

    Would this be the requirement you need. It does seem that taps are not allowed over 600v as they are with 600v and under.

    I don't think 240.21 pertains to over 600V in 2011. What voltage is it and what code cycle. I am guessing if it is the 2014 and your voltage is 1000v or less then it would apply. I see that...

    You are good to go as long as there is no standard size breaker at 750amps. Art. 240.6(A) tells us the standard sizes-- it goes from 700-800 so at 750 amps you can use a 800 amp breaker
