1. How to install a ceiling box for a new light fixture
Select a ceiling box that can support your fixture’s weight. Old work boxes hold up to 6 lb, so heavier fixtures or ceiling fans require a box attached to a steel extendable brace, which can span up to 24 in between joists.
Enlarge the ceiling hole to fit the new box. Hold the box to the hole, trace around it, and cut along the line with a utility knife.
For an old work box, insert it and tighten screws to engage swing clips.
For a brace-mounted box, use a borescope to locate joists and check wire positions. Detach the box from its bracket, punch out two knockouts, and feed the wires through. Insert and extend the brace until snug, ensuring it doesn’t damage stapled wires. Reattach the bracket, pass the wires through the box, and secure the box to the bracket.
Finally, follow the fixture’s manual to install it. Keep the power off until the fixture is completely mounted and ready for use.
