Hi we have just built a porch, and have run cables for outside light and inside light. we have a 2 gang switch that we want to use for each light, one way.
At the switch we have live earth and neutral from consumer unit, not on a loop, end lights. And the same for each light. How do we wire the switch?
Live into the Com terminal of each Switch - you may loop the two Com terminals together - Switched Live from either L1 or L2 of each switch for the respective lamps.
You will have three neutral return conductors - one from each lamp and one from the consumer unit - they will all need to be joined together in a terminal block strip placed inside the switch enclosure box. You do not connect the neutral wires to the switches.
The earth terminal in the wall box (patress) can be used to join the earth conductors - if it's metal it needs to be earthed.
Take care...
