scope:

This part of IEC 60884 applies to switched socket-outlets with interlock for AC only, for fixed electrical installations, with or without earthing contact, with rated voltage above 50 V but not exceeding 440 V and a rated current not exceeding 32 A, intended for household and similar purposes, either indoors or outdoors. Switched socket-outlets with interlock according to this standard consist of a combination of socket-outlets according to IEC 60884-1, interlocked with a switch according to IEC 60669-1 and/or IEC 60669-2-1 supplied as a complete unit. The rated current is limited to 16 A maximum for fixed accessories provided with screwless terminals. This standard does not cover requirements for flush mounting boxes. However, it covers those requirements for surface-type mounting boxes which are necessary for the tests on socket-outlets. NOTES 1 General requirements for mounting boxes are covered by IEC 60670. 2 Interlocked socket-outlets incorporating devices according to IEC 60898, IEC 61008 and IEC 61009 are not covered by this standard. This standard may be used as a guide for the requirements and tests of these accessories where relevant. This document does not apply to - interlocked socket-outlets for industrial purposes; - Interlocked socket-outlets for EV; - interlocked socket-outlets for SELV. Plugs and socket-outlets complying with this document are suitable for use at ambient temperatures not normally exceeding +40 °C, but their average temperature over a period of 24 h does not exceed +35 °C, with a lower limit of the ambient air temperature of −5 °C.
