Step-by-Step Wiring Guide
Follow these instructions to wire your three lights to a single switch:
Step 1: Turn Off the Power
Before starting, you need to turn off the power to the circuit. This can be done at the main electrical panel by flipping the switch that controls the circuit.
Step 2: Plan the Wiring Route
Plan the route that the cable will take from the switch to the lights. Measure the distance from the switch to the first light, and then to the next two lights. Allow extra cable at each end for connections and ensure that the cable is long enough.
Step 3: Run the Cable
Run the three-core cable from the switch to the first light, then to the second, and finally to the third light. Fix the cable to the wall with clips or trunking, and ensure that it is not under tension or twisted.
Step 4: Connect the Live Wires
At the first light, connect the live wire (brown) from the cable to the live wire from the light fixture. Use a terminal block to make the connection, and ensure that it is secure.
Step 5: Connect the Neutral Wires
Connect the neutral wire (blue) from the cable to the neutral wire from the light fixture. Use a terminal block to make the connection, and ensure that it is secure.
Step 6: Connect the Earth Wires
Connect the earth wire (green/yellow) from the cable to the earth wire from the light fixture. Use a terminal block to make the connection, and ensure that it is secure.
Step 7: Repeat for the Other Two Lights
Repeat steps four to six for the other two lights, making sure to use the correct wires.
Step 8: Connect the Switch
Connect the live wire (brown) from the cable to the common terminal of the switch. Connect the switched live wire (brown with red sleeve) from the cable to one of the switch’s other terminals. Connect an earth wire to the switch and the back box if it is metal.
Step 9: Install the Switch Plate
Install the switch plate and screws, and then turn the power back on to test the wiring.
