TL;DR
A tamper-resistant receptacle is an outlet with spring-loaded internal shutters that stay closed unless both slots are pushed simultaneously by the blades of a plug, blocking children from inserting keys, pins, or paper clips. NEC 406.12 has required them in virtually all dwelling locations since 2008, identified by the TR stamp on the face.
What it means
A tamper-resistant receptacle is an outlet with spring-loaded internal shutters that stay closed unless both slots are pushed simultaneously by the blades of a plug, blocking children from inserting keys, pins, or paper clips. NEC 406.12 has required them in virtually all dwelling locations since 2008, identified by the TR stamp on the face. They cost little more than standard outlets, and stiff insertion when new is normal as the shutter mechanism wears in.
