Switched outlets are a common feature in modern homes, used to control the power supply to a specific electrical device. If you are looking to wire a switched outlet, it is important that you follow the right steps to ensure that the wiring is safe and effective. This guide will walk you through the process of wiring a switched outlet, from start to finish.
What is a Switched Outlet?
A switched outlet is an electrical device that allows you to control the power supply to a specific device. The outlet usually has two sets of terminals, one each for the hot (black) and neutral (white) wires. The outlet features a switch that allows you to control the flow of electricity to the device plugged into it. When the switch is on, the device gets power. When the switch is off, the device is disconnected from power.
Switched outlets are commonly used for lamps, computers, televisions and other devices that do not need to be plugged in all the time. By controlling the power supply, you can save energy and reduce the risk of electrical fires.
Wiring a Switched Outlet Diagram
The first step in wiring a switched outlet is to turn off the power supply to the circuit you will be working on. This can be done by turning off the circuit breaker or removing the fuse that controls the circuit. Once you are sure that the power is off, you can begin wiring the outlet.
The following diagram shows a typical switched outlet wiring diagram:
| Wire Color | Function |
|---|---|
| Black | Hot (power supply) |
| White | Neutral (return path) |
| Green or Bare | Ground (safety) |
The switched outlet is wired in series with the hot wire, with the switch controlling the flow of electricity to the outlet. When the switch is on, the outlet is energized and the device plugged into it is powered. When the switch is off, the outlet is de-energized and the device is disconnected from power.
Wiring Steps
Step 1: Gather Your Tools and Materials
Before you begin wiring a switched outlet, you will need to gather the necessary tools and materials:
- Wire cutters
- Wire strippers
- Screwdrivers
- Switched outlet
- Electrical wire (14-gauge)
- Electrician’s tape
Make sure that you have all the tools and materials you need before beginning the wiring process.
Step 2: Turn Off Power Supply
The first step in wiring a switched outlet is to turn off the power supply to the circuit you will be working on. This can be done by turning off the circuit breaker or removing the fuse that controls the circuit. Use a voltage tester to ensure that the power is off before beginning work.
Step 3: Remove Old Outlet
If you are replacing an existing outlet with a switched outlet, you will need to remove the old outlet from its box. Unscrew the cover plate and then unscrew the outlet from the box. Carefully pull the outlet out of the box, taking care to avoid damaging any wires that might be connected to it.
Step 4: Install New Outlet
Insert the new switched outlet into the box, taking care to align it correctly with the screw holes in the box. Attach the outlet to the box using the screws provided. Make sure that the outlet is flush with the wall and that the screw holes are aligned correctly.
Step 5: Connect Wires
Strip the insulation from the wires coming out of the wall, exposing about 1/2 inch of wire. Connect the black wire (hot) to the brass terminal on the outlet and the white wire (neutral) to the silver terminal. Connect the bare wire (ground) to the green screw on the outlet or to the box if it is metal.
Step 6: Connect Switch
If your switched outlet is being controlled by a wall switch, you will need to connect the switch to the circuit. Run an additional length of electrical wire between the switch and the outlet, connecting the black wire to the switch and the white and bare wires to the outlet in the same manner as described in step five.
Step 7: Test the Outlet
Turn the power back on to the circuit and test the outlet to make sure it is working correctly. Plug a device into the outlet and turn the switch on and off to verify that it is controlling the flow of electricity to the device.
FAQ
Q: Can I use a switched outlet for a ceiling fan?
A: No, switched outlets are not designed to handle the electrical load required by ceiling fans. Always use a dedicated ceiling fan outlet for these devices.
Q: Do I need a special switch for a switched outlet?
A: No, any standard wall switch can be used to control a switched outlet. However, you should make sure that the switch is rated for the electrical load that will be carried by the outlet.
Q: Can I install a switched outlet without a ground wire?
A: No, all electrical devices require a ground wire for safety. If your wiring does not include a ground wire, you will need to hire a professional electrician to install one.
Q: Are switched outlets safe?
A: Yes, switched outlets are safe when installed and used correctly. However, they should always be installed by a qualified electrician to ensure that the wiring is safe and compliant with local electrical codes.
Q: How do I know if my wiring is safe?
A: If you are unsure if your wiring is safe, you should consult with a licensed electrician who can evaluate your system and make any necessary repairs or upgrades.
Q: Can I install a switched outlet myself?
A: If you have experience with electrical wiring and feel comfortable working with electricity, you can install a switched outlet yourself. However, if you are unsure about any aspect of the wiring process or do not have experience with electrical work, you should hire a licensed electrician to do the job.
