A 4 gang switch box is a convenient option for controlling multiple lights or appliances from a single location. However, wiring a 4 gang switch box can be a bit tricky, especially if you’re not familiar with electrical wiring. In this article, we’ll provide you with a step-by-step guide on how to wire a 4 gang switch box, along with a wiring diagram and frequently asked questions.
Wiring a 4 Gang Switch Box: Step-by-Step Guide
Before you start wiring your 4 gang switch box, you should make sure that you have the necessary tools and materials. Here’s what you’ll need:
| Tools | Materials |
|---|---|
| Wire strippers | Four single-pole switches |
| Screwdrivers (Phillips and flathead) | Electrical tape |
| Pliers | Four-way switch box |
| Voltage tester | Electrical wire |
Step 1: Turn off the Power
The first step when working with electrical wiring is to turn off the power to the circuit you’ll be working on. You can do this by turning off the circuit breaker or removing the fuse that controls the circuit. Use a voltage tester to confirm that there’s no electrical current flowing through the wires.
Step 2: Remove the Old Switch Box
If you’re replacing an existing switch box, you’ll need to remove it before installing the new four-way switch box. Use a screwdriver to remove the cover plate and screws that hold the old switch box in place. Carefully pull the switch box out of the wall, being careful not to damage the electrical wires.
Step 3: Install the Four-Way Switch Box
To install the new four-way switch box, you’ll first need to measure and cut a hole in the wall to accommodate the box. Use a saw or rotary tool to cut the hole to the correct size, then insert the four-way switch box into the hole. Secure the box to the wall using screws.
Step 4: Wire the Switches
Now it’s time to wire the switches. Start by removing the break-off tabs on the side of each switch, making sure that each switch is rated for the amperage of the circuit. Then, use wire strippers to strip about 3/4 inch of insulation from the end of each wire. Connect the wires to the switches according to the wiring diagram below:

Using electrical tape, cover the exposed wiring connections for each switch. Then, carefully insert each switch into its designated spot in the four-way switch box.
Step 5: Turn on the Power
After you’ve finished wiring the switches, it’s time to turn the power back on. Make sure that all of the switches are in the off position, then flip the circuit breaker or insert the fuse to restore power to the circuit.
