Tamper-resistant receptacles (TRRs) are electrical outlets designed to prevent foreign objects from being inserted into them, reducing the risk of electrical shocks, burns, and electrocution. TRRs are commonly used in locations where children may have access to electrical outlets, such as homes and childcare facilities, to enhance safety. In the context of hospitals, the requirement for TRRs is primarily focused on patient safety, particularly in behavioral health and psychiatric settings. While TRRs can provide protection for patients in these sensitive areas, there are also concerns about their potential to increase disruption to patient care if not properly managed.

Tamper-resistant receptacles (TRRs) are required in psychiatric patient rooms
Tamper-resistant receptacles (TRRs) are designed to protect individuals from electrical shocks, burns, or electrocution. They are identified by the words "Tamper Resistant" or the letters "TR". TRRs have built-in safety shutters that automatically prevent foreign objects, such as fingers, toys, or small items, from being inserted into the receptacle. These shutters only open when equal pressure is simultaneously applied to both vertical slots, allowing a standard plug to be inserted.
TRRs are required in various settings, including private homes, childcare facilities, and hospitals, to enhance safety and prevent accidents. Specifically, in the context of hospitals, TRRs are mandated in psychiatric patient rooms to safeguard individuals who may be at risk of intentional or unintentional electrical hazards. This requirement is outlined in the Facility Guidelines Institute's Guidelines for Design and Construction of Health Care Facilities, emphasizing the importance of tamper-resistant features in these sensitive environments.
The American Society for Health Care Engineering (ASHE) has also addressed the topic of TRR usage in patient settings. While ASHE does not advocate for the combination of TRR with ground fault circuit interrupter receptacles (GFCIs) and arc fault interrupter breakers (AFCIs) due to the increased risk of disruption to patient care, it acknowledges that certain states, like New York, have additional requirements for this combination to enhance the safety of mental health patients. ASHE recommends that health care facilities assess the level of risk associated with electrical usage in behavioral health settings and consider options such as reduction or elimination of receptacles, lockable covers, or switched receptacles in patient bedrooms.
It is worth noting that TRRs are not required in all areas of a hospital. Receptacles located more than 5.5 feet (1.7 meters) above the floor, those that are part of a luminaire or appliance, or receptacles dedicated to specific appliances that are not easily movable are typically exempt from the requirement to be tamper-resistant. However, in areas where the public has access, such as corridors, patient rooms, waiting areas, and toilets, TRRs are generally necessary to ensure the safety of patients, visitors, and staff alike.

TRRs are not required in receptacles located more than 5.5 feet above the floor
Tamper-resistant receptacles (TRRs) are an important safety feature, particularly for protecting children from electrical shocks, burns, and electrocution. They are designed to prevent foreign objects from being inserted into the receptacle, such as fingers, toys, or small items. TRRs are identified by the label "Tamper Resistant" or the letters "TR".
While TRRs are commonly associated with residential and childcare settings, their use in hospitals and healthcare facilities has also been a topic of discussion. The American Society for Health Care Engineering (ASHE) has specifically addressed the use of TRRs in patient settings, particularly in behavioural health and psychiatric patient rooms. ASHE does not advocate for the combination of a TRR, a ground fault circuit interrupter receptacle (GFCI), and an arc fault circuit interrupter breaker (AFCI) as this increases the risk of nuisance tripping, which can negatively impact patient care by diverting staff attention.
However, it is important to note that TRR requirements can vary based on specific regulations and locations within a hospital. For example, TRRs may be required in areas accessible to the public, such as corridors, patient rooms, waiting areas, and toilets. Hospitals should refer to their state and local guidelines, as some states like New York have additional requirements for the use of TRRs in mental health settings.
That being said, it is worth mentioning that TRRs are not required in all receptacles within hospitals. Specifically, TRRs are not mandated for receptacles located more than 5.5 feet (1.7 meters or 1676 millimetres) above the floor. This exception is outlined in various electrical codes, including the National Electrical Code (NEC) and the General Services Administration Electrical Code. The exception also applies to receptacles that are part of a luminaire or appliance and those dedicated to specific appliances that are not easily movable.
In conclusion, while TRRs play a crucial role in enhancing electrical safety, particularly in settings with children, their implementation in hospitals is more nuanced. Hospitals must strike a balance between patient safety and uninterrupted care. Therefore, the decision to install TRRs in hospitals should be carefully evaluated, taking into account specific state regulations, local guidelines, and the unique needs of the patient population.

TRRs are required in corridors, patient rooms, and waiting areas
Tamper-resistant receptacles (TRRs) are an important safety feature in hospitals, especially in areas accessible to the public, such as corridors, patient rooms, and waiting areas. These receptacles are designed to prevent accidental or intentional insertion of foreign objects, reducing the risk of electrical shocks, burns, or electrocution.
In the context of hospitals, TRRs play a crucial role in patient safety, particularly in psychiatric and behavioural health settings. The Facility Guidelines Institute's 2010 Guidelines for Design and Construction of Health Care Facilities specifically address this issue, mandating that "electrical receptacles in psychiatric patient rooms shall be tamper-resistant or equipped with ground-fault circuit interrupters (GFCIs)." This requirement was further emphasised and expanded upon in the 2014 and 2018 Guidelines.
While TRRs are essential in patient rooms, their presence in corridors and waiting areas is equally important. These areas are typically accessible to patients, visitors, and the general public, increasing the risk of unauthorised access to electrical outlets. By installing TRRs, hospitals can minimise the risk of electrical hazards and ensure the safety of everyone in these areas.
However, it is worth noting that the use of TRRs in hospitals is not without controversy. Some states, including New York, have additional requirements mandating the combination of TRRs with GFCIs and arc fault circuit interrupter breakers (AFCIs) for the safety of mental health patients. While this combination may seem advantageous, the American Society for Health Care Engineering (ASHE) does not advocate for its use due to the increased risk of "nuisance tripping," which could distract staff attention from patients.
In conclusion, TRRs are essential in corridors, patient rooms, and waiting areas of hospitals to prevent electrical accidents and ensure patient and public safety. However, the specific requirements and regulations may vary across different states and healthcare facilities, emphasising the importance of consulting local guidelines.

TRRs are not required in receptacles that are part of a luminaire or appliance
Tamper-resistant receptacles (TRRs) are designed to protect individuals, especially children, from electrical shocks, burns, or electrocution caused by inserting foreign objects into receptacles. While TRRs are essential for safety, they are not required in all locations, including certain receptacles in hospitals.
TRRs are not mandatory for receptacles that are part of a luminaire or appliance. This exception is outlined in the National Electrical Code (NEC) and is applicable when specific conditions are met. The exception considers the accessibility and mobility of the appliance in relation to the receptacle.
Firstly, the exception applies to a single receptacle that supplies power to a single appliance or a duplex receptacle that supplies two appliances. This means that if a receptacle is dedicated specifically to powering one or two appliances, it does not need to be a TRR.
Secondly, the exception is contingent on the appliance being located in a designated space or area intended for the appliance. This means that the appliance has its own specific place and is not easily movable from that location under normal usage conditions.
Lastly, the appliance must be cord-and-plug-connected to the receptacle in accordance with specific electrical standards, such as those outlined in Section E3909.4 or 400.10(A)(6), (A)(7), or (A)(8) in some sources. This ensures that the appliance is properly connected and compliant with safety regulations.
In summary, TRRs are not required for receptacles that are part of a luminaire or appliance when the appliance meets the criteria of having a dedicated space, being challenging to move, and being correctly cord-and-plug-connected to the receptacle. These exceptions aim to balance safety requirements with practical considerations in various environments, including hospitals.

TRRs are required in attached and detached garages and accessory buildings
Tamper-resistant receptacles (TRRs) are an essential safety feature in various settings, including hospitals and residential buildings. While hospitals have specific requirements for TRRs in patient rooms and public areas, their primary concern is the combination of TRRs with ground fault circuit interrupter receptacles (GFCIs) and arc fault interrupter breakers (AFCIs). This combination is controversial due to the increased risk of disruption to patient care through nuisance tripping, which the American Society for Health Care Engineering (ASHE) cautions against.
In residential settings, TRRs are mandated by the National Electrical Code (NEC) to prevent electrical accidents, especially involving children. The NEC specifies that TRRs are required in all 15- and 20-ampere, 120- and 240-volt receptacles in one-family homes, each unit of two-family homes, and multifamily dwellings like apartments or condominiums. Notably, this requirement extends to attached and detached garages and accessory buildings.
TRRs in garages and accessory buildings are crucial because these areas may be less supervised or have different electrical usage patterns than primary dwelling units. Garages, for instance, may be used for hobbies or projects involving power tools, increasing the risk of electrical accidents. Similarly, accessory buildings like workshops or pool houses may have unique electrical demands that warrant the added safety of TRRs.
The NEC's mandate for TRRs in attached and detached garages and accessory buildings ensures a consistent level of safety across various residential structures. By installing TRRs, homeowners can prevent accidental electrical hazards, such as shocks, burns, or electrocution, that may occur when foreign objects are inserted into standard receptacles. This proactive safety measure is particularly important for families with young children who may not understand the dangers associated with electricity.
While TRRs are essential in these areas, it's important to note that they are not the only safety measure. Homeowners should also ensure that their garages and accessory buildings adhere to other electrical safety standards, such as proper grounding, secure wiring, and regular maintenance. Additionally, implementing safety practices, such as supervision and education, can further reduce the risk of electrical accidents.
