Description

BS 7657 – Cut-out assemblies up to 100 A rating, for power supply to buildings. Specification

This British Standard specifies requirements for cut-out assemblies up to 100 A rating, for power supply to buildings. Each cut-out assembly provides a means of terminating service cables, protection, a neutral facility and/or a means of earthing the supply, and anti-tamper protection. The primary purpose of the cut-out is to protect the service cable.

Cut-out assemblies are suitable for use on single-phase or three-phase low-voltage public electricity supply systems with a maximum voltage up to 440 V AC and at a frequency of 50 Hz, the neutral being effectively earthed.

The provisions of the general rules dealt with in BS EN IEC 60947-1 are applicable to this standard when specifically called for.
