A double gang switch is a type of switch that controls two separate circuits. The circuits are controlled by separate switches that are mounted in a single housing. The double gang switch is commonly used in areas where two separate lighting fixtures or appliances need to be controlled independently from one another.
Understanding Double Gang Switch Wiring Diagram
Before you start with the wiring process, it is crucial to understand the basic components of a double gang switch. The switch consists of two single pole switches that are mounted in a single housing. Each single pole switch has two terminals, one for the live wire and another for the switch leg.
The live wire is the one that carries the current supply to the switch, while the switch leg is the wire that carries the current to the light fixture or appliance. The switch leg is also known as the load wire.
The wiring diagram of a double gang switch is simply the illustration of how each wire is connected to the switch. It provides a clear understanding of the connection between the live, switch leg, and ground wires.
Wiring a Double Gang Switch
Now, let us take a closer look at the step-by-step process of wiring a double gang switch:
Step 1: Turn Off the Power Supply
Before working on any electrical wiring, it is essential to turn off the power supply to the area you will be working on. This can be done by turning off the switch on the circuit breaker panel.
Step 2: Remove the Old Switch
If you are replacing an old switch, remove it from the wall using a screwdriver. Make sure that the wires are still connected to the switch and mark them with tape to differentiate between the live, switch leg, and ground wires.
Step 3: Prepare the New Switch
Prepare the new double gang switch by stripping off the insulation from the ends of the wires. You can use a wire stripper to remove the insulation up to 1/2 inch from the end of each wire.
Step 4: Connect the Ground Wires
Connect the ground wires to the green screw on the switch. The ground wire is usually bare or green in color and must be connected to the green screw. The ground wire ensures that the switch is grounded and reduces the risk of electrical shocks.
Step 5: Connect the Live Wires
Next, connect the live wires to the two brass screws on the switch. The live wire is usually black or red in color and must be connected to one of the brass screws. Repeat the process to connect the other live wire to the other brass screw.
Step 6: Connect the Switch Legs
Finally, connect the switch legs to the two silver screws on the switch. The switch leg is usually white or yellow in color and must be connected to one of the silver screws. Repeat the process to connect the other switch leg to the other silver screw.
