Project
Low-voltage switchgear and controlgear - Part 7-5: Ancillary equipment - Terminal blocks for aluminium conductors
Abstract
Specifies requirements for terminal blocks with screw-type or screwless-type clamping units primarily intended for industrial or similar use and to be fixed to a support to provide electrical and mechanical connection. This document can be used for terminal blocks for connection between aluminium conductors or aluminium to copper conductors. It applies to terminal blocks intended to connect round conductors, with or without special preparation, having a cross-section between 2,5 mm² and 300 mm² (AWG 12 to 600 kcmil), intended to be used in circuits of a rated voltage not exceeding 1000 V AC (up to 1000 Hz) or 1500 V DC.
