Junction Boxes On Ring Main

[Celtic_Monkey]

Good afternoon everyone,

I'm planning on doing some re-decorating and in the process would like to move some sockets. Rather than have the ring main in the back of the sockets, is it acceptable to use 30amp junction boxes and effectively spur the socket (as in the diagram)? Would make the job a little easier. Load on the sockets are protected with max 13amp plugtops.

If it is possible, is there a max number of junction boxes can be added.

Thanks

It is allowed, but -

the junction boxes will have to remain accessible, or

be maintenance free - one such thing - https://www.tlc-direct.co.uk/Products/ASJ803.html


Having said that, I would not recommend it if the JBs are to be buried in the wall.

Can you not rewire the ring while you are at it?

Junction boxes will not be buried in the wall. The plan was to install loft boarding over the top tho, so would this count as accessible by the fact the loft board could be easily unscrewed & lifted ?

I'll be renovating room by room, so doing the entire ring main in one hit is probably too much unfortunately. The idea behind the junction boxes is to keep the ring main below the loft board (floor) level and just run a single cable to each socket at the new location. Basically it's a plasterboard stud walled bedroom with the ring main in the eaves (running the length of the house on both sides, so access to both sides of room)

Well, I would say not really - but that is what the MF ones are for so would be alright.

Many bungalows have the ring in the loft with all the sockets as spurs from JBs.
