How to Wire a Light Switch and Outlet Combo

Wiring a light switch and outlet combo can seem daunting, but with some basic knowledge of electrical systems and a few tools, you can safely install one in your home. Here is a step-by-step guide to walk you through the process.

Safety Precautions

• Always turn off the power at the circuit breaker before working with electrical wiring. Verify power is off by testing with a non-contact voltage tester.
• Use caution when working inside the electrical box - the wires may still be live.
• Wear personal protective equipment like gloves and safety glasses.
• Only work on wiring that you are qualified to handle. If unsure, consult an electrician.

Gather the Required Materials

Before starting, you will need to gather some basic materials:

• Combo device - Light switch and outlet combined into a single device. Choose one suited for your electrical system.
• Wire strippers - For stripping insulation off wires.
• Voltage tester - To verify power is off before working.
• Wire nuts - For joining copper wires together.
• Electrical tape - For covering splices as an extra safety precaution.
• Screwdrivers - Standard size screwdrivers to access the electrical box.

Turn Off Power and Prepare the Electrical Box

With the right materials gathered, you can now get to work:

1. Turn off power to the circuit you'll be working on at the main circuit breaker panel.
2. Verify power is off by testing with your voltage tester.
3. Remove the existing switch from the electrical box if there is one.
4. Ensure the box is large enough to fit the new combo device and wires. Replace with a larger box if needed.

Connect the Wires

With the box prepped, the wiring is next:

• Identify and label each wire - There will likely be 2 or 3 wires present. The hot wire brings power into the box. The neutral wire continues the circuit. The ground wire connects to the metal box for safety.

• Strip insulation from wire ends using your wire strippers. Strip off 1/2 inch of insulation.

• Connect wires per combo device instructions - There will be screw or push-in terminals on the device. Anchor each wire securely.

• Join ground wires with a wire nut. Connect any grounding wires to the green grounding screw on the device.

• Join neutral wires with a wire nut. The whites are usually the neutral wires.

• No exposed copper should be visible when done.

Install the Combo Device

With the wiring complete, just a few more steps remain:

• Mount the combo device into the electrical box using long screws provided. Tighten screws securely.
• Carefully tuck wires into the box, leaving no exposed copper.
• Install the wall plate cover onto the device.
• Turn power back on at the circuit breaker box.
• Test that the switch and outlet function properly.

Take things slowly and be cautious when dealing with electrical systems. With the right guidance and safety practices, installing a light switch and outlet combo can be a straightforward DIY project accomplished in just an hour or two. Let there be light!
