Connecting Devices for Low-Voltage Circuits for Household and Similar Purposes Part 2-4: Particular Requirements for Twist-On Connecting Devices - Edition 2.0
 N 60998-2-4

Annotation

This International Standard applies to twist-on connecting devices for connecting two or more unprepared rigid and/or flexible copper conductors having a cross-sectional area of 0,5 mm2 up to and including 16 mm2 and complying with IEC 60228, the total cross-sectional area of the connected conductors not exceeding 35 mm2.

It covers low voltage circuits up to 1 000 V a.c. and 1 500 V d.c. where electrical energy is utilized for household and similar purposes.

This standard covers TOCDs primarily designed for application by hand. However, certain TOCDs, for example for large cross-sections, may require the use of a tool designed for that particular TOCD.

NOTE  In the UK, TOCDs must also be suitable for connecting 2 or more unprepared flexible cables, including a flexible cable having a cross sectional area of 1,25 mm2 complying with BS 6500. Wires and cables in the USA do not presently comply to IEC 60228.
