This section applies to plugs, fixed or mobile sockets, and appliance sockets with a safe extra low voltage (SELV) of 6 V to 48 V (including 48 V), direct current or alternating current (50/60 Hz), rated current not exceeding 16 A, for indoor or outdoor use, household and similar purposes. Note 1: We are considering expanding this section to a higher frequency. This section does not include the requirements for concealed installation boxes; Only the requirements for surface mounted installation boxes necessary for testing sockets are included.

Note 3: Sockets that comply with this section are only suitable for use in equipment where the installation method and location cannot cause the ambient temperature around the socket to exceed 40 ℃. Special structures may be required in places with special conditions, such as ships, vehicles, similar places, and hazardous areas where explosions may occur.
