Which UL Standard is used to evaluate and list receptacles?

Explanation:
Understanding how receptacles are evaluated and listed hinges on recognizing which safety standard directly targets them. For receptacles, the standard that covers their design, performance, and testing is UL 498. This standard specifies the requirements for electrical receptacles, outlets, and cord connectors, including ratings, construction, insulation, durability, and grounding. When a receptacle meets UL 498, it can receive UL listing, signaling that it has been tested and complies with safety criteria. The other standards relate to different products—surge protection devices, ground-fault circuit interrupters, and enclosures for electrical equipment—so they don’t govern receptacles themselves.
