Light Fixture Installation in Drop Ceiling

Place the tip of a screwdriver onto one of the knock-outs in the fluorescent light fixture. Tap the back of the screwdriver with a hammer to remove the knock-out.

Insert a box connector into the knock-out. Tighten the nut on the back of the box connector with channel-lock pliers to secure it in the fixture.

Insert 14-gauge black, white and green wires through a piece of flexible conduit. Extend the wires 3 to 4 inches past the end of the conduit. Place one end of the conduit into the box channel. Tighten the screws on either side of the box connector to hold the conduit in place.

Strip 1/2-inch of coating off the tips of the black, white and green wires. Locate the wires coming from the light fixture. Connect the two black wires together with a wire nut. Repeat with the two white wires and then the two green wires.

Tilt the light fixture slightly and raise it up into the ceiling grid. Straighten it out and gently lower it into place. Run the length of attached conduit and wires over to the nearest junction box.

Remove one of the knock-outs from the junction box. Insert a box connector into the knock-out and tighten the nut. Use a hacksaw to cut partially through the flexible conduit. Bend the conduit to separate the two halves. Cut through the exposed wires with a wire stripper.

Place the conduit and wire through the box connector. Tighten the screws to hold them in place.
