Socket not working anymore.

[RDB85]

So last night I noticed that the Socket behind the TV was not working. Plugged in my Kewtech plug tester and nothing. So turned off the MCB for the downstairs sockets. Undone the Socket and its been spurred using new colours from the 13A FCU. Changed the 13A fuse in the FCU, checked the cables and nothing seems out of the ordinary.

There is a socket below that which is wired in Old Colours, which has been there forever. I am just wondering if there is an issue with the FCU, or the wiring itself.

Screwed it all back and then turned the MCB back on. Our house is currently wired in Old Colours, with a Square D CCU. Anyway plugged my socket tester in and again nothing. Would anyone have any ideas what it could be?

Is there any test equipment I could buy to allow me to do some testing, other than a Test Metre as i don't have a lot of money at the moment.

Corrected that for you

So tried again, bought a new lamp for the outside light. Wired the spur so that the Load Side is the Light and the Supply is the sockets. Tested the socket under the bracket. Still not working with the Socket Tester. Tried the FCU with the new lamp. Nothing.

I then looked at the wiring on the RFC, it seems that one of the live (red) is quite short. It reaches into the socket but barely, so I have got a crimping tool, some blue crimps and some 2.5mm2 T&E. So I am going to try and extend any short cables. Although the socket tester has come back all green lights, showing no faults.

So if the light, wired to the new FCU is not working then the problem is going to be before this.
Is your bottom socket functioning ok?

Yes the bottom socket is okay. Tested with a socket tester and it’s all green. TV is plugged in and working.

Edit... Brain fart moment...

So just to recap. The bottom socket is working. This wires to the new FCU which is not working.
Are the wires going from the bottom socket to the FCU ok?

Yes that’s correct. The wiring appears to be okay. No signs of damage. But as mentioned one of the lives although reaches just, is a little short. So I was thinking of maybe adding some blue butt crimps to that and then using some 2.5mm2 twin and earth to extend the cable. Just to see could that be the issue .

The cable length looked ok in the pics you posted up before, but you are there so you will know...
If the light to the new FCU isn't working or the socket wired to the FCU, then it seems to suggest its the cable from the bottom socket to the FCU that may be at fault.

Those cables look okay as I say. Would it be okay to do a butt crimp on the live and use the brown from the 2.5 t&e as a new live?

If you need to extend one on the cables then using a butt crimp and descent heatshrink would be one way of doing it.
Someone did post a nice little inline connector (Not Wago) in a past post, that looked good.

maybe something like this.

Still looking for a current rating, but it does state it can take 12AWG (3.0mm) so should be ok for 2.5mm

Quickest way would be to just bell this wire out for continuity.

Well that's rubbish then...

why? 1 leg of a RFC will never carry >20A. in fact, i think they might be 24A, but too busy opening beers to check.
