A 2 gang box is a commonly used electrical box that allows for two switches or outlets to be installed in one location. Wiring a 2 gang box can seem intimidating, but it is a fairly simple process. In this article, we will provide a step-by-step guide on how to wire a 2 gang box, as well as some frequently asked questions about this type of wiring.
Materials Needed
Before beginning the wiring process, it is important to gather all of the necessary materials.
| Material | Quantity |
|---|---|
| 2 gang box | 1 |
| Switches | 2 |
| Wire stripper | 1 |
| Electrical tape | 1 roll |
| Wire nuts | 4 |
| Electrical wire | 6 feet |
Wiring Process
Follow these step-by-step instructions to wire a 2 gang box:
Step 1: Turn off Power
Before beginning any electrical work, it is important to turn off the power to the area where you will be working. This can be done by shutting off the circuit breaker or removing the fuse that powers the area.
Step 2: Remove Old Box
If you are replacing an old box with a new 2 gang box, you will need to remove the old box first. Use a screwdriver to remove the screws that are holding the old box in place.
Step 3: Prepare Wires
Use a wire stripper to strip the insulation off of the ends of the electrical wires that will be used to connect the switches.
Step 4: Connect Wires to Switches
Connect the black wires to the gold screws on each switch, and connect the white wires to the silver screws. If there is a ground wire, connect it to the green screw on the switch.
Step 5: Connect Wires to Box
Use wire nuts to connect the wires to the 2 gang box. Make sure that there are no exposed wires and that the nuts are tightened securely.
Step 6: Secure Switches in Box
Once the wires are connected, secure the switches in the box using the screws provided. Make sure that the switches are level and flush with the surface of the box.
Step 7: Turn on Power
After the switches are securely mounted in the box and all wires are connected, turn the power back on to the area.
