    I have wired my house to a large central lighting box with only one cable coming out from each switch and light.

    If I wire as the diagram attached, which colours would you use with a 2 way switch for COM, L1, and L2. brown, black, grey?


    Thank you

    My house was wired with a large JB under the floorboards in the corridor.

    I started running new cables for extra switches and i ended replacing the whole thing.I couldn't leave it inaccessible and with old cables.

    So, now I have a junction box in the loft, another one in the bathroom ceiling accessible through a downright hole and the main one next to the CU.

    I'm not an electrician and for me it is easier just to run singles cables using existing routes. Also if in the future I have any issue it would be much easier to find the problem and fix it.
