Outlet covers for babyproofing: caps vs plates vs tamper-resistant outlets
We research products from makers' specs and health sources; we do not run hands-on tests. Links to Amazon may earn us a commission at no cost to you. How this works.
- Self-closing outlet cover plates. Best for: Outlets you use often. See options on Amazon
- Large outlet plugs. Best for: Outlets you rarely use. See options on Amazon
- Outlet box cover for plugged-in cords. Best for: Outlets with cords always plugged in. See options on Amazon
Three ways to protect outlets
| Option | How it works | Weak spots |
|---|---|---|
| Plug-in plastic caps | Push into the slots | Kids can remove some; easy to forget; choking risk if small |
| Sliding or self-closing cover plates | Replace the wall plate; covers slide shut when unplugged | Must fit your outlet style; check that kids cannot pry them off |
| Tamper-resistant receptacles | Built-in shutters block objects in one slot | Replacing an outlet is electrical work |
Based on CPSC's Childproofing Your Home guide and ESFI's tamper-resistant receptacle resources.
What the CPSC recommends
In its childproofing guide, the CPSC lists outlet covers and outlet plates among the safety devices that can help protect children from electrical shock and possible electrocution. It gives three checks:
- outlet protectors should not be easy for children to remove
- they should be large enough that children cannot choke on them
- if you are replacing receptacles, use a tamper-resistant type
The CPSC also says safety devices only work when properly installed and reengaged after use, and that no device is completely childproof, since determined toddlers have overcome or disabled them. Outlet covers are one layer; supervision is still the main one.
Why plastic caps fall short
ESFI cites CPSC data showing that from 1991 to 2001, over 24,000 children under 10 were treated in emergency rooms for receptacle-related injuries, mostly from pushing items such as paperclips, keys or hairpins into outlets.
ESFI, the Electrical Safety Foundation International, points to research from Temple University's Biokinetics Laboratory: 47 percent of 4-year-olds studied could remove one brand of outlet cap, and 100 percent of 2- and 4-year-olds could remove a second brand, often within 10 seconds. ESFI also notes adults often forget to put caps back after using an outlet, leaving it unprotected.
If you use caps anyway, choose large ones that are hard to grip, check them often, and keep a habit of replacing them right after you unplug something. Small caps that come loose are also something a baby could put in their mouth, which is why the CPSC's size warning matters.
How tamper-resistant receptacles work
ESFI says tamper-resistant receptacles (TRRs) look like regular outlets but have internal shutters that block foreign objects. The shutters stay closed if something is pushed into only one side, and open only when a two-bladed or grounded plug goes in. Because the protection is built in, there is nothing to remember to put back.
According to ESFI, the National Electrical Code has required TRRs for 15A and 20A, 125V receptacles in new home construction since 2008, though each state decides when to adopt code versions. ESFI adds that outlet installations should be done by a qualified electrician.
Using tamper-resistant outlets
- First use. ESFI says you may feel the shutter system engage when you first plug in.
- Hard to insert? If a plug needs a lot of force, the plug may be the problem. Carefully straighten bent or splayed blades so both prongs meet the shutters together.
- Damaged plugs. Replace plugs with sharp edges, burrs, cracks or creased blades; forcing them can damage the shutters.
If your home has older outlets, ask an electrician whether swapping in TRRs makes sense, especially in rooms where your baby plays.
Other childproofing to pair with outlets
The CPSC's childproofing list also includes safety gates, cabinet latches, furniture anchors, window guards, corner bumpers and smoke and CO alarms. See our baby gate guide, smoke detector guide and carbon monoxide detector guide.
What to look for when you buy
Self-closing outlet cover plates
Best for: Outlets you use often
Replacing the plate avoids loose caps, which CPSC warns must not be a choking risk.
Watch out: Match the plate to your outlet style; check kids cannot pry it off.
See options on AmazonLarge outlet plugs
Best for: Outlets you rarely use
CPSC says outlet protectors should be large enough that children cannot choke on them.
Watch out: ESFI cites research showing many toddlers can remove caps; check them often.
See options on AmazonOutlet box cover for plugged-in cords
Best for: Outlets with cords always plugged in
Covers the whole outlet and plugs where cords stay plugged in, so slots stay out of reach.
Watch out: Make sure the box fits your plug sizes.

- Are plastic outlet covers safe for babies?
- Only if they are hard to remove and too big to choke on; ESFI cites research that many toddlers can pull out some caps.
- What is a tamper-resistant outlet?
- An outlet with built-in shutters that stay closed unless both plug blades go in together.
- Are tamper-resistant outlets required?
- ESFI says the electrical code has required them in new homes since 2008; states adopt code versions on their own schedules.
- Why is it hard to plug into a tamper-resistant outlet?
- The plug may be bent or damaged; straighten splayed blades or replace damaged plugs.
- Do I still need outlet covers with tamper-resistant outlets?
- ESFI says TRR protection is built in, with no caps to remember; the CPSC still says no device replaces supervision.
