Turn Off Power and Verify the Ceiling Box
1:00
Flip the breaker that controls the ceiling circuit, then test with a voltage tester at the fixture to confirm the power is actually off. Don't trust the switch alone.
Next, check the box the fan will hang from. Standard round electrical boxes are not rated for ceiling fans. You need a fan-rated box that can hold at least 50 pounds of dynamic weight.
If the existing box is just a light-fixture box, stop and install a proper fan-rated brace box before continuing.
Tip
Fan-rated boxes are usually stamped "Acceptable for Fan Support" on the side and come with a spreader bar that wedges between joists. They're cheap and take 15 minutes to install from the attic side.
