Radial Circuit using box installation method...

Former Community Member
Former Community Member
I am curious if anyone has ever done this, and if not any reason?  Is it acceptable? 


So, the scenario is that you install a radial circuit for lighting or sockets for that matter (could apply to either in this instance), and the image I've attached as the example probably isn't the best, but it was the clearest image I could find. 


The example is as follows - you have a circuit coming from the CU on a 16amp radial, rather than just go from one to the other repeatedly could you not use a junction box installation method. As long as the box was accessible.  I know the image shows lighting etc, but I was not thinking of it like that in this instance, it would be either just lighting or just sockets.

    well for a socket circuit you might use 2.5 T & E and use a 16A or 20A MCB (or RCBO) and branch off in all directions or for a lighting circuit use 10A or 6A say in 1.5 or 1.0 T & E . Just as a starter for ten. in fact you could do away with the box and use a socket or a switch or even a ceiling rose as your first or only branch so long as cables and terminations permit being mechanically and electrically robust. Or similarly you can wire as "Tees" or branches, not that uncommon. Or just use "conventional" circuits if that is easier. The world is yer lobster
