480 VOLT LIGHTING WIRING DIAGRAM
How to Wire 277V & 480V, 1 & 3-Phase Main Service Panel?
In 277V and 480V, 1-Phase & 3-Phase, wiring systems, the available voltage levels are as follows inside the main service panel. Voltage between three hot wires (hot 1, hot 2 & hot 3) = 480V, 3-Phase. Voltage between any two hot wires = 480V, 1-Phase. Voltage between any hot wire and Neutral = 277V, 1-Phase.
Understanding 3 phase 480V lighting circuit - Electrical
However, I don't see a 3 phase lighting circuit with 480 V light fixtures work like that. Consider a 3 ph system A, B and C. If the A and B phase are connected to the fixture in a "480V single phase" manner, which phase supplies and which one returns current? Figure 1. The voltage difference between two phases is a sinewave.

Apr 03, 2012On a single phase 480 volt photo control the wiring diagram is the same just that the white wire turns into Line 2 instead of a neutral. I am looking for a remote photo cell wiring diagram for a 480V single phase fixture. great site. seems like you can avoid using a lighting contactor with some of their direct wire photocells. Save
480V lighting versus 277V lighting - Electric power
May 02, 2006If you want to use just part of the lighting at times, switching is cheaper with 277 V. You can use single pole switches for 277, you need double pole switches for 480 volts. Switches for 277 are readily available. 2 pole 480 volt switches are not as common and may be more expensive.
Demystifying 347V and 480V Lighting Installations
The challenge. Many commercial & industrial installations receive primary power at 347V (in Canada) or 480V (US), which often exceeds the rated input voltage for most lighting products. It is hazardous to operate a device beyond its rated voltage & is not acceptable by the local electrical authority. Note: Electrical supply in both Canada and
