  • Entry to substations & switch-rooms to be restricted.
  • Flexible cords /wires should not be normally used.
  • Damaged switches, plugs, fuse boxes, jointing, circuit breakers should be promptly replaced.
  • Electrical installations to be checked at 3 months frequency by inspector using the checkpoints attached.
