摘要:
This standard specifies the requirements for cut?out assembliesup to 100 A rating, for power supply to buildings. Each cut?outassembly provides a means of terminating service cables, fuseprotection, a neutral facility and/or a means of earthing the supply,and anti?tamper protection. Cut?out assemblies are suitable for useon single-phase or three-phase low?voltage public electricity supplysystems with a maximum voltage up to 440 V a.c. and at a frequencyof 50 Hz, the neutral being effectively *** provisions of the general rules dealt with in BS EN 60947-1:2007 areapplicable to this standard when specifically called for.
