How to Replace a Tamper Resistant Receptacle
To replace a tamper resistant receptacle, first make sure the outlet itself is the problem, then turn off the correct breaker, confirm the power is actually off, move the wires to a matching new receptacle, reinstall it, and test it under normal use.
This is a manageable repair for a careful homeowner, but only if the box and wiring are in good shape and you can positively shut off power. The key is replacing the outlet with the same type and reconnecting each wire to the correct terminal.
Before you start: Match the device style, amperage, GFCI or AFCI type, and wiring compatibility before ordering.
Safety first
- Always verify the power is off at the receptacle before touching wires, not just at the breaker panel.
- Replace the receptacle with the same device type and rating unless you know the circuit and wiring support a different one.
- Do not reuse scorched wire ends or install a new receptacle on damaged wiring.
- If the box contains confusing multi-wire connections or signs of overheating, stop and get qualified help.

Step-by-step fix
Step 1: Make sure the receptacle is the right thing to replace
- Check what is actually wrong with the outlet. A worn tamper resistant receptacle often feels loose, grips plugs poorly, has shutters that no longer open smoothly, or shows cracking, heat discoloration, or burn marks.
- Look at the device style before buying a replacement. Match the amperage rating and whether the old device is a standard receptacle, GFCI receptacle, AFCI receptacle, or a combination device.
- If the outlet is dead, test other outlets and check the breaker first so you do not replace a receptacle when the real problem is upstream.
- Remove any plugged-in loads from the outlet before you start.
If it works: You have a matching replacement and a good reason to replace the receptacle itself.
If it doesn’t: If you are not sure whether the outlet is standard, GFCI, or AFCI, stop and identify the device type before buying or wiring anything.
Stop if:
- The box is loose in the wall, melted, scorched, or smells burned.
- The wiring insulation is brittle, charred, or damaged.
- You cannot tell what type of receptacle is installed or the replacement does not match it.
Step 2: Shut off power and verify it is really off
- Turn off the breaker that feeds the receptacle.
- Remove the cover plate and use a non-contact voltage tester at the receptacle slots and around the device screws.
- Unscrew the receptacle from the box and test again near each wire before touching the conductors.
- Keep the breaker off while you work, and keep anyone else from turning it back on.
If it works: The tester shows the receptacle and wires are de-energized.
If it doesn’t: If the tester still shows power, go back to the panel and identify the correct breaker before continuing.
Stop if:
- You cannot positively confirm the power is off.
- More than one circuit appears to be present in the box and you are not confident identifying them safely.
Step 3: Document the old wiring and remove the receptacle
- Pull the receptacle forward gently so you can see the wire connections clearly.
- Take a clear photo showing which wire goes to each terminal before disconnecting anything.
- Note the usual wire positions: hot wires on brass-colored screws, neutral wires on silver-colored screws, and ground on the green screw.
- Loosen the terminal screws and remove the wires. If wires were pushed into backstab holes, release them carefully or cut and re-strip the ends if needed.
- Inspect the copper ends. Trim back damaged or overheated wire and strip fresh insulation only if necessary.
If it works: The old receptacle is free and you have a clear record of how the wires were connected.
If it doesn’t: If the wires are too short to reconnect safely after trimming, the next move is to have an electrician extend them properly in the box.
Stop if:
- A wire breaks off in the box or is too short to reconnect safely.
- You find aluminum wiring, severe corrosion, or signs of overheating deeper in the box.
Step 4: Wire the new tamper resistant receptacle to match
- Compare the new receptacle to the old one and orient it the same way before connecting wires.
- Form neat hooks with needle-nose pliers if you are using side screws, and wrap each hook clockwise so tightening the screw pulls the wire in.
- Connect the ground wire to the green screw, the neutral wire to the silver terminal, and the hot wire to the brass terminal.
- If the old device used separate line and load terminals, move each wire to the matching marked terminal on the new device. Do not guess.
- Tighten terminal screws firmly and make sure no bare copper is exposed beyond what is needed at the terminal.
If it works: Each wire is on the correct terminal and the connections are tight and tidy.
If it doesn’t: If the terminal layout on the new device does not clearly match the old one, compare the markings carefully and use the wiring diagram on the device body before proceeding.
Stop if:
- You are unsure which wire is hot, neutral, line, or load.
- The replacement device does not accept the existing wire size or connection method.
Step 5: Reinstall the receptacle and restore power
- Fold the wires back into the box carefully so the grounding conductor and terminal screws are not forced against each other.
- Screw the receptacle back into the box without overtightening and straighten it so the cover plate will sit flat.
- Reinstall the cover plate.
- Turn the breaker back on.
If it works: The receptacle is secure, the cover plate is flush, and power is restored without tripping the breaker.
If it doesn’t: If the breaker trips immediately, turn it back off and recheck for a hot-neutral mix-up, a ground touching a terminal, or a pinched wire.
Stop if:
- The device will not sit properly because the box is overcrowded or damaged.
- You hear arcing, see sparking, or smell overheating when power is restored.
Step 6: Test the new receptacle in real use
- Use a plug-in outlet tester to confirm the receptacle is wired correctly.
- If the device has test and reset buttons, use them to confirm those functions work as intended.
- Plug in a normal household load that the outlet usually serves and make sure the plug inserts firmly and stays seated.
- Check again after a few minutes of use to make sure the receptacle stays cool and the power remains stable.
If it works: The tester shows correct wiring, the outlet holds a plug properly, and it works normally without heat, tripping, or flickering.
If it doesn’t: If the tester shows an open ground, reversed polarity, or another wiring fault, turn the breaker off and correct the wiring before using the outlet.
Stop if:
- The receptacle gets warm, trips repeatedly, or loses power again under a normal load.
- The tester shows a fault you cannot confidently correct.

FAQ
What is a tamper resistant receptacle?
It is an outlet with internal shutters that open only when equal pressure is applied to both slots at the same time. That helps block foreign objects from being inserted into the outlet.
Can I replace a tamper resistant receptacle with a standard outlet?
Match the existing device type and rating. If the old outlet is tamper resistant, the simplest and safest replacement path is another tamper resistant receptacle of the same type.
How do I know if I need a 15-amp or 20-amp receptacle?
Match the rating of the existing device and the circuit setup. Do not guess based only on what you plan to plug in. The face pattern and device markings can help identify the rating.
Do I need to replace the outlet if plugs are hard to insert?
Not always. Tamper resistant shutters naturally feel stiffer than older outlets. Replace the receptacle if the shutters bind badly, the face is damaged, the plug fit is poor, or there are signs of heat or wear.
What if the outlet is part of a GFCI or AFCI setup?
Then the replacement must match that function. A standard receptacle is not a direct substitute for a GFCI or AFCI receptacle. Move wires to the correct marked terminals and test the device after installation.
