BS 6231

BS 6231 – Electric cables. Single core PVC insulated flexible cables of rated voltage 600/1000 V for switchgear and controlgear wiring.

BS 6231:2006 specifies requirements for construction and performance, and gives methods of testing, for single core, non-sheathed electric cables of rated voltage 600/1000 V having PVC insulation.

The cables are intended for use in the wiring of switch, control, metering, relay and instrument panels of power switchgear, and for such purposes as internal connections in rectifier equipment and its motor starters and controllers. They are intended for use at alternating voltages not exceeding 600 V to earth, and direct voltages not exceeding 1000 V to earth.

When installed in the equipment they are suitable for wiring circuits for which the prescribed alternating test voltage does not exceed 4 kV r.m.s. for 1 min.”
