DIN EN 60998-2-4 VDE 0613-2-4:2006-03

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 qmm up to and including 16 qmm and complying with IEC 60228, the total cross-sectional area of the connected conductors not exceeding 35 qmm.It covers low voltage circuits up to 1000 V a.c. and 1500 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.
