Hi I am planning to change a single switch for a double one as I am adding lights.
The double will then power the existing light and the lv lights I will be installing.
The existing single switch has one red one black and grn/yel tied to the case.
Do I need to run a new cable to the switch from the breaker box?
Or can I run a cable from a joint box in the loft?
Cheers for any help
