38 277v lighting wiring diagram

A 277 volt lighting fixture is one that is usually used in an industrial application. The reason for this is the voltage rating. A voltage potential of 277 volts is the voltage to neutral (ground) of a three phase four wire 480 volt distribution system. 480 volts / 1.73 = 277 volts. If you had 480W 1A stadium lights on 480V delta 20A breakers each lamp is single delta phase and AB , AC or BC then one might choose to derate the breaker to 80% then, 20 x .8 = 16 amps per line. 16 / 1.732 = 9.2 amps per phase. 9 fixtures per phase x 3 = 27 fixtures. The margin allows surge power start.

A 277 panel looks exactly like a 480 3 phase delta panel except that it has a neutral bus (the neutral is generated at the supply ... The metal halide light is a commercial fixture. Wire it to 120 volt. 277 volt is the star point voltage of 3 phase 480 volts. Likewise 347 is the starpoint of 3 phase 600 volt. In this tutorial, 277V and 480V, 1-phase and 3-phase circuits, we have used the NEC + general practice wiring color codes as follows. Yellow = Hot 1 or Line 1. Orange = Hot 2 or Line 2. Brown = Hot 3 or Line 3. White = Neutral Wire. Green = Bare Conductor as Ground wire.
