Step-by-Step Guide: How Do I Switch an Outlet?
Here’s a detailed guide on how to switch an outlet safely and effectively:
- Turn Off the Power: Go to the circuit breaker box and switch off the breaker that controls the outlet. Test the outlet with a non-contact voltage tester and receptacle tester to confirm the power is off.
- Remove the Outlet Cover Plate: Unscrew the screw holding the cover plate in place and remove the plate.
- Unscrew the Outlet: Carefully unscrew the two screws that hold the outlet in the electrical box.
- Pull Out the Outlet: Gently pull the outlet out of the box, exposing the wires. Be careful not to pull on the wires themselves.
- Disconnect the Wires: Note the position of each wire (usually black, white, and green or bare copper) on the old outlet. Loosen the screws holding the wires in place and carefully detach them. If the wires are back-wired (pushed into holes), use a small screwdriver to release them.
- Prepare the Wires: If the wires are frayed or damaged, use wire strippers to cut off the damaged portion and strip about ¾ inch of insulation from the end.
- Connect the Wires to the New Outlet: Connect the wires to the new outlet, matching the colors and positions as before. Black wire to the brass screw, white wire to the silver screw, and green or bare copper wire to the green grounding screw. Ensure the connections are tight and secure.
- Secure the Outlet: Gently push the outlet back into the electrical box, being careful not to pinch the wires. Screw the outlet back into place.
- Replace the Cover Plate: Screw the cover plate back onto the outlet.
- Turn On the Power: Go back to the circuit breaker box and switch the breaker back on.
- Test the Outlet: Use a receptacle tester to ensure the outlet is wired correctly and functioning properly.
Common Mistakes to Avoid
Avoiding these common mistakes will help ensure a successful and safe outlet replacement:
- Failing to Turn Off the Power: This is the most critical mistake! Always double-check that the power is off before starting work.
- Incorrect Wiring: Connecting the wires to the wrong terminals can cause a short circuit or other electrical problems. Always match the colors and positions of the wires on the old and new outlets.
- Loose Connections: Loose wire connections can cause the outlet to malfunction or even start a fire. Make sure all connections are tight and secure.
- Over-Tightening Screws: Over-tightening the screws on the outlet can damage the device and make it difficult to remove in the future.
- Forcing the Outlet into the Box: Trying to force the outlet into the electrical box can pinch or damage the wires. Gently tuck the wires into the box before securing the outlet.
When to Call a Professional Electrician
While how do I switch an outlet? is a valuable skill, there are situations where it’s best to call a professional electrician:

- If the circuit breaker trips repeatedly after replacing the outlet.
Frequently Asked Questions (FAQs)
What type of outlet should I buy?
The type of outlet you buy should match the amperage and voltage of the existing outlet. Most homes use 15-amp or 20-amp, 120-volt outlets. Check the markings on the old outlet to determine the correct type. Tamper-resistant outlets are a good choice, especially in homes with children.
How do I know which circuit breaker controls the outlet?
The easiest way to identify the correct circuit breaker is to test each outlet in the room and note which breaker trips when you plug in a device and flip the switch. You can also use a circuit tracer tool. Always label the circuit breaker after identifying it.
What if I don’t see a ground wire (green or bare copper)?
In older homes, you may not find a ground wire. In this case, you can use a self-grounding outlet that makes contact with the metal electrical box. If the box is plastic, you will need to have a ground wire installed by a qualified electrician.
What if the wires are too short?
If the wires are too short to reach the new outlet, you can use wire extensions to lengthen them. Use the same gauge wire as the existing wiring and connect the extensions using wire connectors. Ensure the connections are secure and properly insulated.
Can I use different gauge wires when extending them?
No, you should never use different gauge wires in the same circuit. This can cause overheating and create a fire hazard. Always use the same gauge wire as the existing wiring.
What are tamper-resistant outlets?
Tamper-resistant outlets have internal shutters that prevent children from inserting objects into the slots. They are a code requirement in many areas and are a good choice for homes with young children.
What is the difference between a 15-amp and a 20-amp outlet?
A 20-amp outlet has a T-shaped neutral slot, while a 15-amp outlet has a straight neutral slot. 20-amp outlets are designed to handle higher electrical loads and are typically used in kitchens and laundry rooms.
What is a GFCI outlet?
A GFCI (Ground Fault Circuit Interrupter) outlet is designed to protect against electrical shock. It monitors the current flow and trips if it detects a leakage, preventing a potentially fatal shock. They are commonly used in bathrooms, kitchens, and outdoor areas.
How do I test a GFCI outlet?
GFCI outlets have a test and reset button. To test the outlet, press the test button. The outlet should trip, cutting off power. To reset the outlet, press the reset button.
Can I replace a GFCI outlet with a regular outlet?
No, you should not replace a GFCI outlet with a regular outlet in an area where GFCI protection is required. GFCI outlets are installed in these locations for safety reasons.
What if the circuit breaker keeps tripping after I replace the outlet?
If the circuit breaker keeps tripping, there may be a short circuit or an overload. Check the wiring to ensure there are no loose connections or damaged wires. If the problem persists, consult a qualified electrician.
How much does it typically cost to have an electrician switch an outlet?
The cost to have an electrician switch an outlet varies depending on location and the complexity of the job. Typically, you can expect to pay between $75 and $200 per outlet. This usually includes the cost of the outlet and labor.
