Power originates from main switchboard MSB-4 feeding distribution panel DP and panel Z. Distribution panel DP feeds two transformers, XFMR TD rated 112.5 kVA and XFMR TK rated 75 kVA, both stepping down from 480V to 120/208V three-phase four-wire service with grounded neutrals. Transformer TD feeds panel A via feeder TA, while transformer TK feeds panel K via feeder TK. An 8"x8" gutter assembly is tied into the distribution system with fused connections.
