What Is a Tamper-Resistant Receptacle?
A Tamper-Resistant Receptacle is an electrical outlet with internal shutters that block access to the energized contacts unless a plug applies pressure to both openings at once. The design helps prevent objects from entering one opening, while preserving normal plug operation. It is commonly installed in homes, offices, and other occupied spaces.

Key Takeaways About Tamper-Resistant Receptacle
- Internal shutters cover the energized contacts.
- A matching plug opens both shutters during insertion.
- Tamper-resistant does not mean ground-fault protection.
How Tamper-Resistant Receptacle Works
A Tamper-Resistant Receptacle contains spring-loaded shutters behind the face openings. The shutters stay closed when pressure reaches only one opening, which helps block objects such as keys or small tools. A properly shaped plug applies balanced pressure to both openings and moves the shutters aside.

The shutter mechanism operates during ordinary plug insertion and does not replace other forms of electrical protection. A Ground-Fault Circuit Interrupter monitors current flow and responds to an electrical imbalance, while tamper resistance addresses access to the contact openings. Receptacle installation also includes checking the box, conductors, grounding path, and connection points for compatibility with the replacement device.
From the Earth Electric team
When we install a tamper-resistant receptacle, we inspect the existing box, conductors, grounding path, and device connections. We also check that the receptacle matches the circuit and that the shutters operate correctly after installation. Our team treats tamper resistance as one part of a broader outlet assessment.
