How to Wire Up a Ceiling Fan When There Are All Black Wires

Most home wiring for appliances such as lights or fans uses a two-wire system, with one wire colored white and the other black. People typically refer to the white wire as the positive and the black wire as the negative. However, since home electrical circuits use alternating current, the distinction is artificial. Unlike direct current electrical circuits--as you'll find in a car--it doesn't matter which wire connects to your power source. If you have a ceiling fan with two black hook-up wires rather than a white and a black wire, you can still hook up the fan safely and easily.

- 2
  Remove 1/2 inch of insulation from each of the black wires connected to the fan, using a set of wire strippers. Remove 1/2 inch of insulation from each of the input wires on the circuit you'll be connecting to, using a set of wire strippers.
- 3
  Take one of the black wires and place its bare end next to and parallel with one of the input wires. Slip a wire nut over the bare wires and twist it to the right until it securely fastens onto the bare wires and covers them completely.

  Take the other black wire and place the bare end next to and parallel with the other input wire. Slip a wire nut over the bare wires and twist it to the right until it securely fastens onto the bare wires and covers them completely.
