Wagos in a 2G socket backbox....

Former Community Member
Former Community Member
I'm running through the options with regards to terminating a 4mm2 ring when it comes to the sockets. For some of the 2G sockets there is plenty of space to easily / reliably terminate the 4mm2 cable, in others not so much.


What would be a whole lot easier (there is plenty of space as I fitted 35mm back boxes) would be to loop in and out via a couple of wago 221 3-way connectors using the 3rd way as a spur to the socket, allowing just a single cable needing to be clamped down at the socket terminal itself.


I'm sure I won't have been the first to have thought of this.


Thoughts please? The only limitation I can see is that I would'nt be able to spur off the socket (but could of course just use a wago with more ways).


It has been a long week and I just wanted to sense check this........


Thanks in advance

    Really you are looking at getting (2 x4.0) + 2.5 into the terminals to allow for a spur, which should be perfectly achievable because you could be using the same fittings for a 4.0 mm radial circuit.


    You should not be having a problem in the first place.

    Agreed ... BUT you may be surprised that spurring off a 4 mm2 ring or radial exceeds the terminal capacity stated in BS 1363-2:



    11.5 Line and neutral terminals in fixed socket‑outlets shall permit the connection, without special preparation, of one, two or three 2.5 mm2 solid or stranded or of one or two 4 mm2 stranded conductors as given in Table 4 of BS 6004:2012.





    and



    11.6 Earthing terminals in fixed socket‑outlets shall permit the connection, without special preparation, of one, two or three 1.5 mm2 or 2.5 mm2 solid or stranded or of one or two 4 mm2 stranded conductors.





    This terminal capacity is what's quoted in a number of manufacturer's ranges ... so the OP really does have a point, especially if you want to spur off anywhere it's a good idea, and perfectly reasonable in my opinion.
