I just bought a 175 watt metal halide, it's all wired up and from what I can tell it's ready to go. I need to wire a cord to it and it has 3 wires sticking out for the cord. One is black, the other is white, and the last one is green. The ballast says 277 volt and 60 hz, is that normal to run off of a regular house circuit? The guy I bought it from is an electrician and he actually just stuck the 3 wires into an outlet and it worked but it had the mercury vapor bulb in it at the time which looked kinda dim?
