I fitted an isolation switch for an extractor fan. The cable to the fan runs around 3 walls, so I could easily tap into it by drilling through from outside the bathroom.
The cable is T&E (switched live, neutral and earth) so there is no permanent live to the fan (no run on). The switch I have is a triple pole isolation switch but I just used L1 and N and left the L2 empty so its working as a double pole isolation switch.
I connected the earths together using a connector, but would it have been OK to connect the earths using the spare L2 of the switch?
