Before you can connect your fixtures, you will need to call an inspector to make sure you've followed code. Connecting your wiring is relatively simple, thanks to the push terminals located on the back of most fixtures. If, for any reason, you find a wire won't quite reach, never tape two wires together to make it longer. Separate wires should always be joined at a junction or an electrical box - nowhere else. Color code both ends of some of these wires so that even after your walls are covered, you ll know which wire goes where.
Black wire goes in brass side.
To install the fixture, first take your wire strippers and remove of an inch of the protective sheathing from the black and the white wires. Simply push it in and that push terminal automatically clamps onto the wire for a nice, tight fit. Then the white wire, which is neutral, goes into the silver side in the same way. The bare copper wire, called a grounding wire, is looped around the green screw on the bottom end of the receptacle. When you tighten that screw down, you will automatically secure your connection.
