Free a core

Former Community Member
Former Community Member
I have a switch which is looped in through sweet


it has a

L&N into it

L&N out

3 core out to its 2way

switch wire coming out


its current a 1g switch, which is 2wAyed


my question is, 


Is it possible to free up one of these cores in the switch, for a possible new switch wire? I don’t want to damage the walls with chases. 


the switch is currently wired with the brown of 3core into the common

The black and switched live is in L1

The grey and perm lives are in L2

neutrals are in connector

earths also in a connector

    are you asking if you can free up the LN going in an and out ?

    If they both come from the same direction, and assuming you do not need a neutral at the switch for any reason, the neutral junction could be elsewhere, potentially freeing up 2 cores.

    It is not clear from you description if you intend to keep the 2-way functionality. If you do not need this either  you could free up the 3 core as well.

    thanks for the response.


    sorry if I got you lost.


    The 2 way switching is staying.


    I want to put some down lights in the room, but also keep the central light. I don’t want to chase the walls to put in a new cable.


    In regards of the L&N in and out they come from below, which, is in accessible. There is no floor boards that I can get to these. The 3core 2wAy and the switch wire go up the way, which I can access in the floor boards 


    does this make it a little clearer?

    OK 5 cables,  LNE feed in LNE  feed out, down, and then upwards the  LNE switched supply to lamp and the  3 core to another switch, In any case the 3 core has a core in common with the switched live supply to the lamp - they could be split higher up ?

    Yes, I can put a maintain free JB upstairs if you could tell me what I could do to free the core.

    I had a brain fart.


    If I locate the 3core and Switched live upstairs. I split these and put into a JB 


    I can then keep 3core browns with each other


    greys together


    blacks together, along with the brown from the light , leaving the brown going down to the switch free?

    connect blues together so I still have neutral up there, given me a free core?


    will this work?
