How to Replace a 15 Amp Tamper Resistant Receptacle
To replace a 15 amp tamper resistant receptacle, turn off the correct breaker, verify the outlet is dead, move the wires to a matching new device one connection at a time, reinstall it neatly, and test it before regular use.
This is a manageable repair if the box and wiring are in good shape and you can positively shut off power. The key is replacing the receptacle with the same type and reconnecting the wires exactly where they came from.
Before you start: Match the device style, amperage, GFCI or AFCI type, and wiring compatibility before ordering.
Safety first
- This repair is only for a de-energized receptacle you have personally verified is dead.
- Replace the receptacle with the same general device type and rating, especially if the old one is a GFCI or other special outlet.
- Do not reuse scorched wire ends or damaged terminals.
- If you find heat damage extending into the cable or box, stop and repair the underlying wiring problem before installing a new receptacle.

Step-by-step fix
Step 1: Make sure this is the right repair
- Look for signs the receptacle itself has failed, such as loose plug grip, cracked face, heat discoloration, scorch marks limited to the device, or a broken tamper-resistant shutter.
- Confirm you are replacing the same kind of device. If the old outlet has TEST and RESET buttons, it is a GFCI and should be replaced with the same type, not a standard receptacle.
- Check the face marking and branch circuit setup so you are replacing it with a matching 15 amp tamper resistant receptacle style.
- If the problem affects multiple outlets, lights, or breakers, pause and make sure the issue is not upstream from this one.
If it works: You have a failed or worn receptacle and a matching replacement device ready.
If it doesn’t: If the outlet looks fine but the circuit still has broader power problems, troubleshoot the breaker, GFCI, AFCI, or upstream wiring before replacing the receptacle.
Stop if:
- The electrical box is loose, broken, burned, or too damaged to hold a new device safely.
- You find melted insulation, charred wires extending into the cable, or signs of overheating beyond the receptacle itself.
- You cannot identify whether the existing device is standard, GFCI, AFCI-related, or otherwise special.
Step 2: Shut off power and verify the outlet is dead
- Turn off the breaker that feeds the receptacle.
- Remove the cover plate with a screwdriver.
- Use a non-contact voltage tester at the receptacle slots and around the screws before touching the device.
- Unscrew the receptacle from the box and gently pull it forward, then test again near each wire and terminal.
If it works: The receptacle is pulled forward and you have confirmed there is no power at the device or its conductors.
If it doesn’t: If anything still tests live, go back to the panel and identify the correct breaker before continuing.
Stop if:
- You cannot positively confirm the power is off.
- The tester shows voltage on one conductor after the breaker is off and you are not sure why.
Step 3: Document the wiring and remove the old receptacle
- Take a clear photo of the existing wire locations before disconnecting anything.
- Note which wire is on the brass-colored side, which is on the silver-colored side, and where the ground wire is attached.
- If two cables enter the box, pay close attention to which conductors are paired on each side of the receptacle.
- Loosen the terminal screws and remove the wires. If the old device uses push-in backstab connections, release them with the slot on the back or cut and re-strip the wire ends if needed.
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 wire positions are confusing, compare your photo to the new device and label the wires before moving on.
Stop if:
- The wire insulation is brittle, burned, or too short to reconnect safely.
- You open the box and find mixed wire sizes, doubled wires that do not fit the new device properly, or wiring that does not match a basic receptacle replacement.
Step 4: Connect the new receptacle to match the old one
- Attach the bare or green ground wire to the green grounding screw first.
- Connect the white neutral wire to the silver-colored terminal and the black hot wire to the brass-colored terminal.
- If the box has feed-through wiring, move one conductor at a time to the matching side so the new receptacle is wired exactly like the old one.
- Tighten the terminal screws firmly and make sure no bare copper is exposed beyond the screw connection.
- If you had to trim damaged ends, strip only enough insulation for a clean, secure connection.
If it works: The new receptacle is wired to match the original layout with tight, clean connections.
If it doesn’t: If the wires do not reach comfortably or the terminal layout does not match what came out, stop and compare the new device carefully before energizing anything.
Stop if:
- The replacement receptacle does not accept the existing wiring method or conductor count safely.
- A conductor will not tighten securely under its terminal.
- The grounding path is missing or damaged.
Step 5: Reinstall the receptacle neatly in the box
- Fold the wires back into the box in gentle bends so they are not pinched behind the device.
- Set the receptacle upright and fasten it to the box.
- Install the cover plate and tighten it just enough to sit flat without cracking.
- Make sure the receptacle face is straight and the cover plate is not forcing the device out of alignment.
If it works: The new receptacle is mounted securely, sits straight, and the cover plate is installed cleanly.
If it doesn’t: If the device rocks or will not sit flush, pull it back out and rearrange the wires so the box is not overcrowded behind the receptacle.
Stop if:
- The box is too shallow, damaged, or loose to support the receptacle securely.
- The cover plate or device will not fit because of crowding or damaged box hardware.
Step 6: Restore power and test it under real use
- Turn the breaker back on.
- Use a plug-in outlet tester to confirm the receptacle is wired correctly.
- Plug in a lamp, charger, or similar normal load and make sure the connection feels firm and steady.
- After a few minutes of use, check that the receptacle stays cool and the breaker does not trip.
If it works: The new receptacle tests correctly, holds plugs firmly, and works normally without heat or nuisance tripping.
If it doesn’t: If the tester shows an open ground, reversed polarity, or another wiring fault, turn the breaker back off and recheck each connection against your photo and the terminal colors.
Stop if:
- The breaker trips immediately after power is restored.
- The receptacle gets warm, crackles, sparks, or smells hot.
- The outlet tester shows a fault you cannot correct confidently.

FAQ
Can I replace a 15 amp tamper resistant receptacle myself?
Many homeowners can if they can shut off the correct breaker, verify the outlet is dead, and move the wires to a matching replacement carefully. If the wiring is damaged or confusing, it is safer to stop.
What does tamper resistant mean on a receptacle?
It means the outlet has internal shutters that help block foreign objects from being inserted. It still works normally with a standard plug when both blades go in together.
Do I need to replace it with the exact same kind of outlet?
Yes, match the basic device type. A standard receptacle should be replaced with a standard tamper resistant receptacle, while a GFCI receptacle should be replaced with a GFCI type unless the circuit is being changed intentionally and correctly.
Why does my new outlet feel tighter than the old one?
That is usually normal. New tamper resistant receptacles and new contact springs often grip plugs more firmly than a worn outlet.
When should I call an electrician instead of replacing the receptacle?
Call if you find burned wires, a loose or damaged box, repeated breaker trips, confusing multi-cable wiring, missing grounding, or any sign the problem is larger than one failed receptacle.
