TR Receptacles – What exactly does tamper-resistant mean? If I shove a screwdriver into one socket, does it zap, or does something need to be pushed into both holes?

In receptacles, tamper-resistant refers to the safety mechanism built in to the receptacle to prevent unintended insertion of a foreign object into a single side of the outlet. It is designed to allow a plug to be properly inserted, but prevent an object from inserting into only one slot of the outlet. Our Tamper-Resistant outlets are compliant to NEC code 406.12
