How To Wire A Combo Switch Outlet With Constant Power

How to Wire a Combo Switch Outlet with Constant Power: A Comprehensive Guide

This article provides a step-by-step guide on how to wire a combo switch outlet with constant power. This type of outlet is incredibly useful, providing both switched and unswitched power from a single unit. Perfect for lamps that need to be controlled by a switch, while also powering devices that need to remain on continuously. This guide assumes you have basic electrical knowledge and experience; if not, consult a qualified electrician. Safety should always be your top priority. Incorrect wiring can lead to electrical hazards.

Understanding the Components:

Before starting, let's understand the components involved:

• Combo Switch Outlet: This unit combines a standard duplex outlet with a single-pole switch.
• Electrical Box: The enclosure that houses the wiring and outlet.
• 12/2 or 14/2 Romex Cable: The wiring used to connect the outlet to the power source. The gauge (12 or 14) depends on the amperage of the circuit.
• Wire Strippers/Cutters: To safely strip the insulation from the wires.
• Screwdrivers: For tightening the screws on the outlet and switch.
• Voltage Tester: To ensure the power is off before working on the wiring.
• Wire Connectors (Wire Nuts): For securely joining wires together.

Step-by-Step Wiring Instructions:

1. Turn Off the Power: This is the most crucial step. Locate the breaker controlling the circuit and switch it to the "OFF" position. Use your voltage tester to confirm the power is off at the outlet location.

2. Remove the Old Outlet (if applicable): If replacing an existing outlet, carefully remove it from the electrical box. Unscrew the mounting screws and pull the outlet out, taking note of the wiring configuration.

3. Prepare the Combo Switch Outlet: Familiarize yourself with the wiring terminals on the combo switch outlet. They are typically labeled, with terminals for:

• Hot (Black): This wire carries the power.
• Neutral (White): This wire completes the circuit.
• Ground (Green or Bare Copper): This wire provides safety grounding.
• Switched Hot (Black): This wire goes to the switch and controls the switched outlet.
• Unswitched Hot (Black): This wire provides constant power to the unswitched outlet.

4. Connect the Wires: Here's how to connect the wires to the combo switch outlet:

• Hot (Black): Connect the incoming hot wire to the "Unswitched Hot" terminal on the combo switch outlet.
• Neutral (White): Connect the incoming neutral wire to the neutral terminals of both outlets on the combo switch outlet.
• Ground (Green or Bare Copper): Connect the incoming ground wire to the ground terminal on the combo switch outlet and the electrical box.
• Switched Hot (Black): Connect the incoming hot wire to the switch's terminal, and then connect the switch's output terminal to the "Switched Hot" terminal of the combo switch outlet.

5. Secure the Wires and the Outlet: Tuck all the wires neatly into the electrical box. Make sure the wire nuts are secure and the wires aren't strained. Securely mount the combo switch outlet to the electrical box using the provided screws.

6. Test the Circuit: Turn the breaker back to the "ON" position. Test both the switched and unswitched outlets to ensure they are working correctly. Use the voltage tester again to ensure the wiring is sound.

Troubleshooting:

• Outlet doesn't work: Recheck all wire connections. Make sure the breaker is turned on. Verify the hot wire connections to the switch and outlets.
• Switched outlet doesn't work: Inspect the switch and its connections. Ensure the switch is properly wired to the "Switched Hot" terminal.
• Both outlets don't work: Double check all your connections, focusing on the incoming hot and neutral wires. Ensure the breaker is on and functional.

Important Considerations:

• Always turn off the power before working with electrical wiring.
• Use the correct gauge wire for the amperage of the circuit.
• If you are not comfortable working with electricity, consult a qualified electrician.
• This guide is for informational purposes only and does not constitute professional electrical advice.

By following these steps, you can successfully wire a combo switch outlet with constant power, adding convenience and functionality to your home. Remember safety is paramount – if in doubt, call an electrician.
