Via the internet I am trying to help a friend swap a standard two gang two way rocker switch for this Holder two gang two way dimmer switch - which has 5 terminals instead of the normal 6. There is a single common L.
The two gang dimmer is sited in the hallway with gang 1 linked to a single rocker landing switch and both operate the landing light.
Gang2 controls the hallway light.
Both the landing and hallway lights are on their own RCD protected circuit.
As I read it if the circuit is wired as per the instructions for the two way circuit - then for the one way hallway circuit I only need a switch live into the LHS arrow 1 - but won't that create a borrowed neutral? Won't putting the hallway live loop into L and switch live arrow 1 create the same situation?
I thought of wiring the two way circuit using the 'standard' method Live loop = L1 Switch Live = L2 then using the three strappers - but the Common L on the Holder switch will still cause the problem.
If this is correct, aside from putting both lighting circuits on the same mcb, has anyone got an idea how I can remove the potential for a borrowed neutral.
