Confused- I isolated the kitchen sockets by flicking the RCD trip to the kitchen sockets then went to cut the 2.5mm cable in the kitchen and the house lights lights tripped. What's going on? Do I need to turn off at main switch in order to add new cable and sockets?
The house is on 4 rings (?) downstairs sockets (RCD protected), Kitchen sockets, upstairs sockets and lighting (RCD protected)
