Help me wire my 400w ballast to my fixture, please!
    #486512 - 10/09/10 07:55 PM (14 years, 5 months ago)

Hey everyone, I could REALLY use your help with this, I don't wanna fuck it up at all. So I gutted this old fixture
(I know its raggedy, but it's all ive got to mount this new 400w ballast in:
.
I also have this power cord:
.

This is how I plan on doing it, please correct me if I'm wrong! There were 4 wires (I'm assuming for power) labeled 277v(black), 240v(tan), 206v(purple), and 120v(orange). I capped off all but the 120v since my wall outlet uses 120v. That leaves 4 wires exposed:
.
1 Red wire that goes to the light socket, 1 white COMMON wire that goes to the socket, 1 white COMMON wire that goes to the wall outlet, and the orange 120v wire that goes to the wall outlet. Is there supposed to be a ground, or can I just ground it from my power cord to ground it to the metal in the fixture? And how do I know which to connect the 120v/COM wire to? (+ or -? e.g. white or black). It would be better for me if I go with an ungrounded setup. Is that possible, just not safe?

This is the schematics that came with the ballast if it helps:
.
Someone pleeeeeease help me out here, it's my first go at this and I dont wanna do it wrong! Thanks in advance!! =)

Yeah, it's safe, it's just an old fixture. The ballast, resistor, ignitor and ALL of the wiring is brand new and I'm building a frame to mount it to from chains and putting about 4 small fans in the space, plus intake/output ventilation. I just wanna get the wiring right so it doesn't start any electrical fires. or burn up the first time I fire it up (No pun intended lol).

Yeah, they usually are here too, but if it's the 277v that I capped. I'm wondering if it's like a car, and you can ground to anything metal on the frame? Well, thanks your your input bub, I'll wait for hopefully someone with some experience.

I just wired it all up, bolted the components down, hooked up the power cord (with the ground, thanks again lol), installed the light, and gave her a test run. It works awesome, so thank you again for the good advice Amnesiac! Is there any way I can give u cred/return a favor online? This is how it all worked out:
