UK How to extend the wiring loop

[Dan_swx]

I have recently moved into a house and am giving it a full refurb. The wiring in one of the rooms has me stumped! I found a junction box under the floorboards and found that the only plug socket in the room was spured off this too (now removed).

The two wires on the right go one direction into the room (one through a wall into another room and not sure on the other) and the two on the left come from outside the room (they do no enter the room together and come from different directions).

Can anyone help me find the wiring loop so I can extend it and add a few plug sockets to it safely.

Thanks everyone for your support! I have actually sorted this matter now. There was another wire that wasn’t connected to anything and terminated under the floorboards with insulation tape around it.

The wiring is actually safer than when I started ??

I would make sure you get an electrician to test the circuit for your own peace of mind. Better now while the floor is up. Also, get them to change the junction box for an MF type.

How do you know? What testing have you carried out?

Well at the moment I haven’t done anything other that remove two spur sockets and the live wire under the floorboard.

Yup. And do you still have continuity of the ring when you test it at the consumer unit?
PS I’m hoping that you checked continuity before you started this work?

Continuity? The telly works when i plug it in...whats wrong with that?......GET A SPARKY

Just to expand on DPG's comment: Here MF = maintenance free, a type of connection (and matching box) that is designed not to loosen with time/vibration/thermal cycling. If you search on various sales sites you will find ones meeting this. Usually this is a spring-loaded type that maintains pressure, where as screws run the risk of loosening over time and are more likely to be too tight or too loose if you don't have experience or a torque screwdriver (and actually use it, not just leave it in the cupboard!).

Wago are generally the favourite here, but be aware that you need to get the correct combination of box and terminal to meet the MF designation. Also take care as usually the push-on Wago (and similar brands) are only suited to solid (i.e. single core) wires, whereas the clamp-type of terminal will work with both solid and stranded wire.

But as already said, it is always better to avoid junctions if you possibly can (and doubly so if concealed) and run new cable from socket to socket for your ring.

Let's not forget that there are some MF boxes out there that will only satisfy the MF criteria once they have been closed and sealed with a Ziptie, closing alone will not qualify as MF (even though you used push fit connectors)

Eh? I don’t think so.
there are some MF boxes out there that only comply as an MF ASSEMBLY if they are used in association with the correct connectors.
For example, Wago connectors in the appropriate WAGOBOX.
Anything else does not comply with
BS EN 60670.

@Lister1987 is correct. Line 3 of the MF instructions provided with a Wagobox specify that the lid should be secured with a cable tie. This is in the seperate section of the pamphlet on how to achieve MF compliance with the product

The bang test?

Might as well have put them around Ashley 401's for all the good.
Still the best uns for me.
