TC 23 Scope

TC 23

To coordinate the work between the different subcommittees of TC 23 and with other technical bodies within and outside IEC.

To prepare standards for electrical accessories for household and home and building electronic systems and similar purposes, the word “similar” including locations such as offices, commercial and industrial premises, hospitals, public buildings, etc.

These accessories:

- are intended for fixed installations (including HBES installation), or for use in or with appliances and other electrical or electronic equipment, and may include electronic components.

- are normally installed by instructed or skilled persons and are normally used by ordinary persons.

Include, in particular:

- conduit systems

- cable trunking systems

- cable ducting systems

- cable support systems

- switches (mechanical and electronic)

- Home and Building Electronic Systems (HBES)

- HBES switches and related accessories for use in Home and Building Electronic Systems (HBES)

- plugs and socket-outlets

- cable reels

- cord extension sets and cord sets

- Devices for the Connection of Luminaires (DCLs)

- adaptors

- circuit breakers for overcurrent protection

- devices protecting against electric shock

- contactors

- connecting devices

- enclosures for accessories

- appliance couplers

- electrical Energy Efficiency products.

Note 1) For the terms "instructed persons", "skilled persons", and "ordinary persons" see Publication IEC 61140; 3.30, 3.31 and 3.32.

A lot of standards for these products are handled by the subcommittees of TC 23. But some products are under the direct responsibility of TC 23 due to their nature, such as :

a) Standards for single phase and multiphase installation couplers intended for permanent connection in fixed installations with a rated voltage up to and including 500 V a.c. and a rated connecting capacity up to and including 10 mm² in indoor electrical installations.

b) Standards for sound signalling devices with integral enclosures or sound signalling devices intended to be fitted into or supplied with enclosures according to IEC 60670 intended for household and similar purposes with rated voltages greater than 50 V a.c. or 75 V d.c. and not exceeding 250 V a.c. or 250 V d.c., and with rated power inputs not exceeding 100 VA.

c) Standards for Electrical safety, Environmental Conditions, Functional Safety. EMC and Installation of HBES

d) Standards for clamping units for connecting devices for the connection of electrical conductors having a cross-sectional area of 0,2 mm² up to and including 35 mm² copper conductors and up to and including 50 mm² aluminium conductors with a rated voltage not exceeding 1000 V a.c. and 1500 V d.c. intended for household and similar purposes.

e) Standards for connecting devices as separate entities for the connection of two or more electrical conductors having a cross-sectional area of 0,2 mm² up to and including 35 mm² copper conductors and up to and including 50 mm² aluminium conductors with a rated voltage not exceeding 1000 V a.c. and 1500 V d.c. intended for household and similar purposes.

f) Standards for male and mating female flat quick-connect terminations for use as either an incorporated or an integrated part of an equipment or of a component, or as a separate entity, for connecting electrical copper conductors up to and including 6 mm2 with a rated voltage not exceeding 1000 V a.c. and 1500 V d.c. intended for household and similar purposes.

TC 23 has Group Safety Function 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-sectional area of 0,2 mm² up to and including 35 mm² copper conductors and up to and including 50 mm² aluminium conductors, but excluding connecting devices intended for data and signal circuits.
