Whats the power supply amperage and voltage of a lithonia 400 watt high bay? Thanks!

With this fixture, you can use either 120 V, 277 V or 347 V. If you're going with a plug-in configuration, it would most likely be 120 V. Before just wiring a plug, it is best to open up the ballast compartment to verify that the 120 V lead is connected to your cord and plug. You will find lots of wires coming out of the ballast. You want to hook up the 120V one on your cord set black, the COM one on your cord set white (and wire up the ground, it will be the same no matter the voltage).

In case you're wondering, the 277 V and the 347 V are typically used in 3-phase buildings, and most of the time are hardwired (although plugs do exist and are different from 120 V or 240 V ones).

On 120V, the ballast will draw 4 amps. The other amperage ratings given are for 277 V and 347 V, respectively.

Make sure you cap off the unused wires separately.
