i am used to the red, black, white, green and bare cables. but i got a chanelier with two black cables and a bare cable (ground) so how do i put it up?
Just hook up one of the black wires to your white wire out the ceiling, and the other black wire to the black wire from the ceiling
Use a continuity tester to determine which wire goes to the lamp shell. That's the neutral, connect it to the white in the ceiling box. The other goes to the switch leg. If you were to hook it up in reverse it would work but you could easily get shocked changing a bulb with the power still on. The bare wire is of course the ground.
