This standard specifies the 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, fuse protection, a neutral facility and/or a means of earthing the supply, and anti‑tamper protection. 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 a.c. and at a frequency of 50 Hz, the neutral being effectively earthed. The provisions of the general rules dealt with in BS EN 60947-1:2007 are applicable to this standard when specifically called for.
