JIS C 2814-2-4:2001

This Standard applies to twist-on connecting devices for connecting two or more unprepared rigid and/or flexible conductors having a cross-sectional area of 0.5 mm*2 up to and including 16 mm*2 and complying with IEC 60228 or related JIS, the total cross-sectional area of the connected conductors not exceeding 35 mm*2. It covers low voltage circuits up to and including 1000 V a.c. or 1500 V d.c. where electrical energy is utilized for household and similar purposes. This Standard is to be used together with JIS C 2814-1. In this Standard, twist-on connecting devices are abbreviated to TOCDs. 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.
