CGW: Your utility have any "approved" meter stacks?
We have run 600 to 1600 into a Sq D stack. 3 phase, 4 wire, 277/480 with 200amps to each tenant space. 100 amp 480 feed to 75 kva xfr to 42 circ 120/208 w/200 or 225 MCB.
For anything above 200 self contained (w/CT cab) a plug-in section w/?? MCB to CT & then to space.
Our utility requires 'cold sequence', so main before CT/Meter.
