Before starting any electrical work, it’s essential to verify that the circuit that powers the wall lights is switched off at the breaker panel. This ensures your safety while working with electricity.
2. Locate the Electrical Box
Remove the wall plate covering the electrical box where your wall lights are connected. This will expose the wires and terminals within the box.
3. Identify the Power Source
Look for two wires that are connected to the terminals on the wall lights. One of these wires will be black, indicating the hot wire that carries electricity from the power source, while the other will be white, representing the neutral wire that completes the circuit.
4. Identify the Fixture Wires
The other two wires within the electrical box are connected to the wall lights. Usually, one of these wires will be black and the other white. The black wire is the power supply for the lights, while the white wire returns the current to the neutral wire.
5. Determine the Switch Configuration
Depending on the type of switch being used, the wiring configuration may vary. If a single-pole switch is being used, the black power source wire will connect to the common terminal of the switch, while the black fixture wire will connect to the terminal that is not the common terminal. If a double-pole switch is being used, the black power source wire and the white power source wire will connect to the common terminals of the switch, while the black and white fixture wires will connect to the other two terminals.
6. Understand Other Wiring Configurations
| Wiring Configuration | Description |
|---|---|
| Ground Wire | A bare copper or green wire that provides a safety path for electrical faults. |
