About this detail

An electrical distribution single-line diagram details the connection from a 400A, 480V/277V 3-phase, 4-wire, 42KAIC switchboard designated "SWB1061HM" feeding a 45kVA mechanical power transformer "TNF1064LM" stepping down to 480V-208Y/120V 3-phase, 4-wire with 3.5% impedance. The transformer secondary supplies a 225A, 208Y/120V 3-phase, 4-wire, 10KAIC mechanical power panel board designated "EDP1062LM" protected by a 150A 3-pole breaker. A grounding conductor of size 3/4-inch conduit with one #2 AWG ground connects to the transformer. Circuit connections and feeds are routed through designated conduit paths.
