God willing, and the creek don't rise (again!) I'll be installing 11 runs of 750KCMIL w/ 250 KCmil grounds monday
at first sniff that 250 seemed a tad small
but they're not calling it a neutral
they're calling it a groundING conductor (there's your 12.5%)
and 'earthing' a noodle from the 4000A 480 switchgear
this was engineered , and done so with both the poco and architectual engineers working in unision btw
all code ref's aside, i just don't like creating something that is readilly available, especially in close proximty to so many potential returns to the serving xfomer (or the other 2000A xfomer bank aboput 40' away)
