scope:

This part of IEC 60884 applies to switched socket-outlets with interlock for a.c. 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 standard does not apply to

 - interlocked socket-outlets for industrial purposes;

 - interlocked socket-outlets for SELV.

Accessories complying with this standard are suitable for use at an ambient temperature not normally exceeding 25 °C, but occasionally reaching 35 °C.
