What Is A Tamper Resistant Outlet?
Tamper Resistant Outlets (TRRs) are a type of receptacle designed to provide a permanent solution to the potential risks of childhood shocks caused by tampering with electrical outlets. TRRs feature built-in safety shutters that block foreign objects from being inserted into the outlet. These shutters are an essential safety feature that help protect young children from the dangers associated with electrical outlets.
Since 2008, TRRs have been required by the National Electrical Code (NEC). This regulatory requirement reflects the recognition of the importance of implementing measures to prevent children from accidentally inserting objects into electrical outlets, which can lead to severe electrical shock or burns. By installing TRRs, caregivers and parents can have peace of mind knowing that their children are protected from the potential hazards of tampering with electrical outlets.
- TRRs provide a permanent solution to childhood shocks caused by tampering with electrical outlets.
- TRRs have built-in safety shutters that block foreign objects from being inserted into the outlet.
- TRRs are required by the National Electrical Code (NEC) since 2008.
- Installing TRRs provides peace of mind for caregivers and parents.
“TRRs are an essential safety feature that helps protect young children from the dangers associated with electrical outlets.”
How Tamper Resistant Outlets Work
The operation of Tamper Resistant Outlets (TRRs) is based on the design of their built-in safety shutters. These shutters are located inside the receptacle and function as a barrier to prevent any foreign objects from being inserted into the outlet. The shutters remain closed unless a 2-bladed or grounded plug is inserted.
The mechanism behind TRRs is such that if an object is inserted into one side of the receptacle, the shutters of the other side remain closed, blocking any access. This ensures that only when a proper plug is inserted can the shutters open, providing access to the electrical current.
It is important to note that TRRs are not designed to prevent accidental shocks caused by touching the metal prongs of a plug when they are partially removed from the outlet.
Other safety measures, such as Ground Fault Circuit Interrupters (GFCIs) and Arc Fault Circuit Interrupters (AFCIs), address different electrical hazards and are often used in conjunction with TRRs for ensuring overall electrical safety.
- TRRs have built-in safety shutters that prevent foreign objects from being inserted into the outlet
- Only a proper plug can open the shutters and provide access to electrical current
- TRRs do not prevent accidental shocks caused by touching partially removed plugs
- TRRs can be used alongside GFCIs and AFCIs for comprehensive electrical safety.
Note: TRRs provide an additional layer of protection by preventing foreign objects from being inserted into the outlet, but they are not a substitute for other electrical safety measures.
Importance Of Tamper Resistant Outlets
The implementation of Tamper Resistant Outlets (TRRs) is of paramount importance in ensuring the safety of children. Young children are naturally curious and may be tempted to insert objects into electrical outlets, unaware of the potential dangers associated with it. TRRs provide a vital layer of protection by effectively blocking foreign objects from accessing the electrical current.
The significance of TRRs lies in their ability to prevent childhood injuries and fatalities caused by accidental electrical shocks. Through the use of TRRs, families and caregivers can significantly reduce the risk of electrical accidents, ensuring a safe living environment for children.
Ensuring The Proper Functioning Of Tamper Resistant Outlets
To ensure the proper functioning of Tamper Resistant Outlets (TRRs), it is important to perform regular maintenance and checks. If excessive force is required to insert a plug into a TRR, it is likely that the plug itself is damaged, not the receptacle. In such cases, it is crucial to replace the damaged plug to maintain the safety features of TRRs.
Additionally, plugs with bent or splayed blades should be carefully straightened out, ensuring that each prong contacts the shutters simultaneously. Damaged plugs with sharp edges or uneven blade tips should also be replaced promptly as inserting damaged plugs into any receptacle may cause further damage and compromise the outlet’s safety features.
Regulatory Requirements And Recommendations For Tamper Resistant Outlets
Tamper Resistant Outlets (TRRs), along with Ground Fault Circuit Interrupters (GFCIs) and Arc Fault Circuit Interrupters (AFCIs), are mandatory in all new and renovated homes based on the regulations outlined in the National Electrical Code (NEC). These regulatory requirements highlight the recognition of the importance of electrical safety and the need for implementing measures to prevent accidents caused by electrical hazards.
To ensure optimal installation and functioning of TRRs, it is highly recommended that all outlet installations be performed by a qualified electrician. Electricians have the expertise and knowledge to ensure the proper installation, maintenance, and adherence to regulatory requirements, safeguarding the electrical safety of households.
TRRs are an essential component in maintaining electrical safety, particularly in households with young children. By providing a permanent solution to childhood shocks caused by tampering with electrical outlets, TRRs play a crucial role in preventing potential accidents and keeping children safe. Compliance with regulatory requirements and seeking professional installation ensures the optimal performance and effectiveness of TRRs.

Frequently Asked Questions
Why do you need tamper resistant outlets?
Tamper resistant outlets, or TRRs, are a crucial addition to our electrical systems for several important reasons. Firstly, they serve as a permanent solution to the potential danger of childhood shocks caused by the tampering of electrical outlets. TRRs are equipped with built-in safety shutters that prevent foreign objects from being inserted into the receptacle, significantly reducing the risk of accidents. This feature ensures that children, who are naturally curious and prone to exploring their surroundings, are protected from potential electrical hazards.
Additionally, tamper resistant outlets provide a long-term safety measure for all individuals using electrical appliances. By blocking foreign objects from being inserted into the receptacle, TRRs not only prevent accidental shocks but also safeguard against potential fires caused by short circuits. This advanced safety feature ensures peace of mind and greatly reduces the risk of electrical accidents, making tamper resistant outlets an essential component in all electrical installations.
What are required tamper resistant outlets?
Required tamper-resistant outlets are a safety measure that has become mandatory for all 15- and 20-ampere receptacles in homes. These outlets feature built-in shutters that effectively prevent children from inserting any foreign objects into the receptacle slots. These tamper-resistant receptacles help to provide a safer living environment by reducing the risk of electrical accidents, particularly to curious children who may be prone to explore their surroundings in potentially dangerous ways. By integrating this feature into the outlets, homes can now better protect against the potential hazards associated with the misuse of electrical outlets, promoting greater peace of mind for families.
What is the difference between TR and WR outlets?
The main difference between TR and WR outlets lies in their respective indications and purposes. The “TR” mark or etching on a device strap is a visual confirmation of tamper resistance, ensuring an added layer of safety. On the other hand, the “WR” identifier serves as a quick indication during inspections that a weather-resistant receptacle has been installed, providing protection against moisture and outdoor elements. While TR outlets prioritize tamper resistance, WR outlets focus on durability against weather conditions.
Are tamper resistant outlets safe?
Yes, tamper resistant outlets are indeed safe. Designed to prevent electrical contact with foreign objects, these receptacles provide an effective measure to avoid electric shock and potential fatalities. By incorporating barriers within the outlet slots, tamper resistant receptacles ensure the safety of individuals, particularly children who might be tempted to insert objects into the outlet. With their ability to prevent accidental shocks, tamper resistant outlets offer a reliable and essential safety feature that gives peace of mind to users, making them a trustworthy choice for all electrical installations.
