I have an advance F-can ballast for a 175w metal halide bulb.
I bought a powercord for it at wallmart, but all it says is that the ribbed wire is the neutral wire.
The ballast has 4 wires comming out of it. A red and white wire that go to the lamp, and a 277v yellow wire and a 120v black wire.
I assume that it doesn't matter which wires the red and white wires connect to as long as they connect to the bulb socket.
My question though is which wires do I connect to the powercord? Do I connect the 120v back wire on the ballast to the neutral wire on the powercord?
