The other day I bought a fluorescent light fixture that I want to use for growing carnivorous plants. I paid extra for the light to come pre wired with a three-pronged plug and cord but, alas, it did not. So instead of waiting an extra week for them to send me the cord and or have to pay the extra money to send the light back to them, I've decided to just do it myself.
So far, everything seems ok. I bought an 8 foot pre-stripped cord that can be plugged into the wall, a bag of wire nuts, and a knock-out adaptor to hold the cord in the fixture.
The cord has three wires: black, white, and green. I've already connected them to the black and white wires from the fixture, and the green ground wire has been wrapped around a green screw in the fixture.
The fixture, on the other hand, has three wires, too: black, white, and grey with red stripes. The problem I'm having is what to do with this grey/red wire. When I put bulbs in the fixture, only half of them light up, so obviously this is because the grey/red wire is not connected to anything, and it clearly powers half the lights.
My question is, how do I connect this grey/red wire to the cord if the black wires are already connected? There are no more wires for me to connect to. Is it possible to wire both the black and grey/red wires from the fixture to the one black wire on the cord?
Thanks a lot!
Edit: Just got off the phone with contractor lighting again, and they told me to connect the grey/red and black wires from the fixture to the one black wire on the cord. I had no idea you could safely connect three wires together. Now I know. I'd still like to know what you guys think about this, so I'm not going to delete the post. Thanks!
