Hello I have the following situation:
an existing 1200 amp main switchboard (MSB), fed with 3 sets of 500 kcmil, I'm also adding a new load is a UPS (300amp load) fed by 1 set of 500 kcmil through a 400 amp disconnect switch.
I'm proposing a new ATS, which have inits load side 4 sets of lugs, here is my question: Can use three (3) lugs to feed the MSB and 1 set of lug to feed my 400 amp disconnect? (all together is 4 set of lugs)
Thanks
