The voltage of 277 volts is the wye voltage of a three phase 480 volt distribution. In the 480 volt CDP (Central Distribution Panel), you will need a 600 volt rated single pole 15 amp breaker installed in the CDP. The load will be connected to the output terminal of the breaker and the other conductor will be connected to the neutral bus in the CDP. The minimum size conductor for the 15 amp circuit will be a #12 copper conductor.

How do you wire a 240 volt street light circuit?
A 240 volt street light circuit is wired in parallel connections. In the base of the street fixture an inline fuse is connected into the circuit that goes up to the fixture to protect the lamp head.
Is there a way to install a 277V light on a 120V circuit?
no ----------------------------------------------------------------------------------- Stepdown transformer. More expensive than buying the correct light fixture. Y-THINK-Y
A 24 volt battery supplies three devices wired in parallel that each have a resistance of 9 ohms. What is the voltage drop across each device?
A simple circuit has three resistors connected in series. The resistors are 14 ohms 12 ohms and 9 ohms. What is the total resistance of the circuit?
Why do white wire mark 120v?
Because the white wire on a 120 volt circuit is the neutral wire that is connected to the silver screw on outlets and switches. It is connected to the neutral bar in the service panel.
How is the total load in volt-amperes for lighting purpose determined?
LxW of building x 3 volt amps per sq. foot
