We are feeding a second floor 250 K UPS with 400-amp, 480 volts from an outside 600-amp MDP, droping back down outside to an 225 KVA transformer which feeds a 600 amp main breaker panel 120/208 volt.
Should I have a disconnecting means on the second floor for the UPS?
Should I have a disconnect outside on the primary side of the transfomer?
Wash. DC area and are on the 2005 NEC.
