|ICS Code (Plugs, socket-outlets, couplers):||29.120.30|
This part of IEC 60884 applies to plugs and fixed or portable socket-outlets for a.c. only, with or without earthing contact, with a rated voltage greater than 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.
The rated current is limited to 16 A maximum for fixed socket-outlets provided with screwless terminals.
This standard does not cover requirements for flush mounting boxes; however, it covers only those requirements for surface-type mounting boxes which are necessary for the tests on the socket-outlet.
NOTE 1 General requirements for mounting boxes are given in IEC 60670.
This standard also applies to plugs incorporated in cord sets, to plugs and portable socket-outlets incorporated in cord extension sets and to plugs and socket-outlets which are a component of an appliance, unless otherwise stated in the standard for the relevant appliance.
This standard applies to fixed switched socket-outlets for a.c. only, with or without earthing contact, with a rated voltage not exceeding 440 V and a rated current not exceeding 32 A, intended for household and similar purposes, either indoors or outdoors.
In some countries, the use o f single-pole switches is not allowed.
Switched socket-outlets can also be produced by combining a socket o f IEC Publication 884-1 and a switch o f TEC Publication 669-1.
This standard does not apply to
-- plugs, socket-outlets and couplers for industrial purposes;
-- appliance couplers;
-- plugs, fixed and portable socket-outlets for ELV;
NOTE 2 ELV values are specified in IEC 60364-4-41.
-- fixed socket-outlets combined with fuses, automatic switches, etc.
NOTE 3 Socket-outlets with pilot lights are allowed provided that pilot lights comply with the relevant standard, if any.
Plugs and fixed or portable socket-outlets complying with this standard are suitable for use at ambient temperatures not normally exceeding 25º C, but occasionally reaching 35º C.
NOTE 4 Socket-outlets complying with this standard are only suitable for incorporation in equipment in such a way and in such a place that it is unlikely that the surrounding temperature exceeds 35º C.
In locations where special conditions prevail, such as in ships, vehicles and the like and in hazardous locations, for example where explosions are liable to occur, special constructions may be required.
