Replacement:
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 mm 2 up to and including 1 6 mm 2 and complying with IEC 60228, the total cross-sectional area of the connected conductors not exceeding 35 mm 2 .
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 mm 2 complying with BS 6500. Wires and cables in the USA do not presently comply to IEC 60228.
