    I'm leaning this way myself. 22A x sqrt(3) = 38A. The nameplate (or spec's) say 36, so there could be a small load across the otherwise open end of the delta configuration... or if 4-wire, some...

    As noted... but looking at it the other way around

    800A or less OCPD rating, the conductor ampacity value has to be greater than the next lower standard OCPD rating value.

    Over 800A OCPD, the...

    I have to wonder how you're going to run a ground ring just around the expansion. To qualify as a ground ring, it has to run around the entire building. EVen if you manage to do this just for the...
