Change Summary

• New requirements were added for receptacle outlets with USB charger(s).

Expert Analysis

A new requirement has been added to Article 406 at 406.3(F) pertaining to 125-volt 15- or 20-ampere receptacle that additionally provides Class 2 power in the form of an USB charger. These new provisions require these devices to be listed and constructed such that the Class 2 circuitry is integral with the receptacle. Outlet devices consisting of a Class 2 power supply and Class 2 output connector(s) are presently readily available to the public. Some of these assemblies are intended to be secured and directly connected to a duplex receptacle. The combination of the Class 2 assembly and duplex receptacle has not been investigated to national standards. The product standard for receptacles, ANSI/UL 498 (Attachment Plugs and Receptacles), contains requirements that correspond to the required construction as well as the performance requirements to evaluate the suitability of a receptacle with integral power supply with Class 2 output connectors. Requiring the use of a listed receptacle with integral power supply with Class 2 output connectors will confirm that the installed device complies with the appropriate product standard.
