Numpty (me) damaged 2.5 TE cable in plastered wall

[user 34456]

Unfortunately you just sometimes have to make a mess.......

This one was damaged when fitting a curtain rail bracket,,, unfortunately the wall was dot & dabbed without any capping or trunking so it needed to be cut out at the dabs.... I made the joint using Wago's in a Wiska box with stuffing glands in the ceiling void

Yes, I would have bitten the bullet and done much the same had Mike P not come up with a bright suggestion. It would have been easier for me to feed a new length than your dot and dab situation. I could easily splice in a new piece of capping and finish the wall, but the cut-out in the ceiling was my main concern which I really want to avoid. Food for thought though....

And so far... I have NEVER had to bury any joints part-way up a wall..
BUT I have come across numerous failed buried joints during fault finding on various circuits!!!

So from my personal experience I would say it is a daft idea to consider a bury-the-joint option...
even if technically BS7671 is happy with inaccessible maintenance-free joints!

Some well made points - Thank you.

I bet its capping not conduit.

Wagos (in a box) are maintenance free, so yes bury in a wall no problem.

(I am not going to say about the 1.5 mm cable going to the FCU)

Cant see a problem with the 1.5 mm feeding the fcu.
