If you've ever tried to plug something into an electrical outlet, only to find that there's some plastic blocking you from doing so, you're not alone. This plastic is part of a tamper-resistant outlet, designed to prevent children from sticking objects or their fingers into the prongs and potentially harming themselves. To use these outlets, you need to push the plug straight in so that both slots open simultaneously. While they can be a nuisance, tamper-resistant outlets are now required by code in the US and Canada for accessible outlets.

What You'll Learn

Tamper-resistant outlets
TRRs feature a built-in spring-loaded shutter mechanism that blocks foreign objects from being inserted into the outlet. The shutters are designed to open only when equal and simultaneous pressure is applied to both slots, as would occur when inserting a proper electrical plug. This simple yet ingenious design effectively blocks most attempts by children to insert objects into one slot, significantly reducing the risk of electrical shock.
The National Electrical Code has required TRRs since 2008, and they are now standard in the US and Canada for accessible outlets. TRRs offer a permanent solution to the problem of childhood shock caused by tampering with electrical outlets, providing peace of mind for homeowners concerned about electrical safety.
Unlike removable plastic outlet covers, which can be forgotten or misplaced, TRRs provide constant protection. Studies have shown that TRRs are nearly 100% effective in preventing electrical injuries related to outlet tampering, surpassing the protection offered by traditional outlets, even with plastic safety covers.

Child-proofing
Tamper-resistant outlets have plastic covers that require both slots to be pushed on simultaneously and with equal pressure for the plug to slide in. This prevents children from inserting objects into one slot. The outlets can be a bit finicky and may require some wiggling and rocking back and forth of the plug to make proper contact. Cheaper outlets may also require more force to insert the plug.
Some people may find these outlets frustrating to use, especially if the prongs on their plugs are not identical in length. In this case, it is important to angle the plug so that the shorter prong enters at the same time as the longer one, turning it straight as it enters.
For those who find these outlets extremely frustrating, standard non-tamper-resistant receptacles can still be purchased online, although they may be harder to find in local hardware stores.

Ground Fault Interrupter Circuit (GFI)
The plastic on the outlet refers to the sliding protector on a receptacle, which is also known as a Ground Fault Interrupter Circuit (GFI) or a Ground Fault Circuit Interrupter (GFCI). These outlets are designed to prevent electrocution and electric shocks, particularly in places that might get wet. They are also used to prevent children from tampering with the outlet and inserting objects into the prongs.
GFCIs are safety devices that protect against ground faults, where electricity has found an unintended path to the ground, such as through a person's body. This can lead to a potential shock or electrocution. GFCIs sense the difference in the amount of electricity flowing into and out of a circuit, even in small amounts of current, and will trip the circuit if there is a discrepancy. This prevents electricity from passing through a person's body and causing harm.
There are three types of GFCIs: the most common is the "receptacle-type" GFCI, which is similar to a standard wall outlet. The second type is the circuit breaker GFCI, which replaces a standard circuit breaker and provides protection to all receptacles on that circuit. The third type is the portable GFCI, which can be plugged into an existing outlet to provide GFCI protection to devices plugged into it.
GFCIs are now required for many appliances, such as hair dryers, to prevent accidents and fires. They are also commonly used in areas where the outlet is accessible, such as in homes with small children, to prevent tampering and ensure safety.
It is important to note that while GFCIs provide a layer of protection, they should not be solely relied upon for safety. Proper use of electrical appliances and outlets is crucial to prevent accidents. Additionally, regular testing and maintenance of GFCIs are necessary to ensure their effectiveness.

Plastic flaps
Tamper-resistant outlets are required by code in the US and Canada and are increasingly common in new constructions. They are also found in the UK, where all sockets have been shuttered for decades. While these outlets are an important safety feature, some users have found them annoying or frustrating to use, as they can be finicky and require some force to insert a plug.
To use a tamper-resistant outlet, it is important to push the plug straight into the outlet so that both slots open simultaneously. In some cases, it may be necessary to wiggle the plug or rock it back and forth to get it to insert properly. It is also important to note that cheaper tamper-resistant outlets may require more force to open than higher-end ones.
While these plastic flaps are an essential safety feature, they can be removed in certain situations. For example, some people may choose to replace their tamper-resistant outlets with standard non-tamper-resistant receptacles, especially in areas where children are not present. However, it is important to consult with a certified electrician before making any electrical modifications to ensure safety and compliance with local codes.

Resetting the GFI
The plastic on the outlet is a safety feature known as a tamper-resistant receptacle. It is designed to prevent children from sticking objects into the prongs of the outlet. To use an outlet with this feature, you need to push the plug straight into the outlet so that both slots open simultaneously.
Now, if you're having trouble resetting a GFI (Ground Fault Interrupter Circuit) outlet, there are several steps you can take to troubleshoot the issue:
- Check if there are any other GFI outlets in your home, garage, basement, or outside areas. GFI outlets are usually wired together, so resetting the others may solve the problem.
- Ensure that you are pressing the reset button firmly enough. Some GFI outlets require a certain amount of pressure to reset.
- Verify that there is power going to the GFI outlet. GFI outlets may not reset if they are not receiving power. Check the main breaker and turn it on and off again if necessary.
- Inspect the wiring to ensure there are no loose connections. Loose wires can prevent the GFI outlet from resetting. If you find loose wires, you may need to call an electrician for assistance.
- Check for moisture buildup in the wiring or outlet. If moisture is present, dry the outlet with a hairdryer before attempting to reset it.
- Consider the age of the GFI outlet. GFI outlets typically last between 10 and 15 years. If your outlet is older than 10 years and you cannot find any other issues, it may be time to replace it.
- Consult a qualified electrician. If none of the above steps work, it is best to seek professional help. An electrician can troubleshoot the problem and determine if there are any underlying issues with your electrical system.
Remember, electrical issues can be complex and potentially dangerous. If you are unsure about anything, it is always best to contact a licensed electrician for assistance.
