IEC SC 23C WORLD-WIDE PLUG AND SOCKET-OUTLET SYSTEMS

• to prepare dimensional standards for a world-wide unified system for plugs, socket-outlets and couplers for cord-extension sets for household and similar general purposes;
• to elaborate the basic characteristics of a modular system, if possible suitable for all kinds of household installations and the definition of principles for its use.;
• to co-ordinate information for the introduction of the unified system and to make all efforts to ensure the harmonization of supplementary or transitional configurations necessary for certain countries, as stated by TC 64.

IEC SC 23E CIRCUIT-BREAKERS AND SIMILAR EQUIPMENT FOR HOUSEHOLD USE

• to prepare standards for:
  • circuit-breakers and residual current devices of rated currents not exceeding 125 A and rated voltages not exceeding 440 V for protection against overcurrents and/or against electric shock in domestic and similar installations;
  • residual current devices for monitoring the conditions of insulation of domestic and similar installations;
  • circuit-breakers of rated currents not exceeding 125 A and rated voltages not exceeding 440 V designed to protect equipment for use in domestic and similar installations;
  • electromechanical contactors for household and similar purposes;

The standards concern devices intended to be used by unskilled and uninstructed persons in installations or equipment not subject to maintenance and contain all specifications necessary for certification purposes:

Close coordination is held with the work of SC 17B on standards for similar switchgear for general use.

IEC SC 23F CONNECTING DEVICES

• to prepare standards for connecting devices, either as separate entities or as integral parts of an end product, primarily for connecting external electrical supply conductors, for use with conductor cross- sections of between 0.5 mm˛ and 35 mm˛, but excluding connecting devices for data and signal circuits.

IEC SC 23G APPLIANCE COUPLERS

To prepare standards for:

• Appliance couplers for making a detachable connection between a cord connected to supply of household and similar general purpose equipment.
• Cord sets intended for the connection of household and similar general purpose equipment to the mains, and
• Interconnection couplers and interconnection cord sets for the interconnection of household and similar general purpose equipment.

The work of the Subcommittee takes into account the specifications prepared by TC 34, TC 61, TC 74 and TC 92.

Close co-operation is maintained with the other Subcommittees within TC 23.

IEC SC 23H INDUSTRIAL PLUGS AND SOCKET-OUTLETS
