I've been to an office block today to move some lights in a suspended ceiling and label the light switches with it's operation. There was a 12 way grid switch with 3 banks of 3 switches and an emergency light test switch. Each bank of switches was fed via its own mcb and on a different phase.
Do I need to put a warning label on the switch warning that it contains 415 volts and it needs isolating at multiple supplies?
Many thanks
