ECN Forum Forums Code Related Discussion NEC & other Code issues Separately Derived Systems in the same pull box?

I am currently installing a generator for optional standby loads in an office building. The Generator has two output breakers, one feeds a 120/208 ATS, the other feeds a 75kVA transformer near the generator for a 277/480V feed for a 277/480 ATS for the lighting loads. I also have a conduit with 277/480V feeders for a transformer & sub panel near the generator for the engine heater & battery charger ect. Can all of these conduits & feeders share the same junction box for an angle pull?

TIA,
Mark

Yes, being that this is an optional standby system.
