BS 5372:1997+A1:2012

This British Standard specifies the dimensions to be observed in the design of cable terminations, having uninsulated conductor fittings, to enable the satisfactory connection of external cables to electrical equipment. It covers 2-core, 3-core and 4-core 600/1000V and 3-core 1900/3300V cables having extruded solid dielectric insulation and stranded copper conductors and solid or stranded aluminium conductors, as appropriate, of size 10 mm² to 300 mm².

The standard is based on the use of compression type conductor terminations and allows for the cores to be crossed within the terminal enclosure because this combination requires more space.

NOTE1 The choice of conductor size depends on installation conditions which are outside the scope of this standard. Annex B lists some of the factors which should be considered.

NOTE2 This standard does not permit any reduction of the specified minimum electrical clearances in the relevant equipment product standard.

NOTE3 Guidance as to the requirements for cable terminations for single core cables are given in annex A.
