Always test the power by flipping the light switch a few times before proceeding.
Look for wires marked NM-B, UF-B, THHN, or THWN-2. These wires are approved for the higher-temperature fixtures.
According to the National Electric Code (NEC), a fixture that weighs 50 pounds or more will have to have its own independent electrical box.
Adjust the length of the rod by aligning the canopy with the crossbar and allowing a little screw thread to extend through the canopy. Lock the length in place with a lock nut. Thread the screws into holes on each side of the crossbar. If you’re using a rod, thread it into the center hole of the crossbar.
Have a helper hold the rest of the fixture while you connect the wires.
If you’re using a center-mounted ceiling light, slide the canopy onto the rod so the nipple shows through the center hole. Screw on, and tighten the mounting nut. If needed, adjust the rod so that the canopy sits flush against the ceiling.
