Introduction of GB/T 13140.1-2008

Connecting devices for low-voltage circuits for household and similar purposes - Part 1: General requirements 1 Scope This part of GB 13140 applies to connecting devices as separate entities for the connection of two or more electrical copper conductors (complying with GB/T 3956-2008 or GB/T 18213-2000) rigid (solid or stranded) or flexible, having a cross-sectional area of 0.2mm2 up to and including 35mm2 and equivalent AWG conductors with a rated voltage not exceeding 1,000V a.c. up to and including 1,000Hz and 1,500V d.c. where electrical energy is used for household and similar purposes. Note: Rated connecting capacities lower than 0.5mm2 are referred to GB/T 18213-2000 and rated connecting capacities equal to, or higher than, 0.5mm2 are referred to GB/T 3956-2008. Connecting devices that require the use of special tools other than for twist-on connecting devices and insulation piercing connecting devices do not comply with this part. This part contains the general requirements to be used together with the relevant Part 2, containing detailed particular requirements for: ——devices with screw-type clamping units (GB 13140.2) ——devices with screwless-type clamping units (GB 13140.3) ——devices with insulation piercing clamping units (GB 13140.4) ——devices with twist-on connecting devices (GB 13140.5) 2 Normative references The following normative documents contain provisions which, through reference in this part of GB 13140, constitute provisions of this part.
