Mira 9.9 kw Shower

[m4tty]

Hi,

My friend rung me earlier and said his shower was smelling and the casing is very hot at the top. So had a look and took the cover off and attached are the pictures.

I take it this neutral was not tightened up enough and its been arcing which has caused the insulation to burn?

I saw the cable goes through wall lower than bottom of shower and shows when front is replaced on shower. I know this is not good so what would be best without chasing in and replaing tile. Trunking (siliconed up to make water tight) ??

Also would it be ok to cut the neutral back (past charred insulation) and crimp and insulate with new bit of cable and run it passed the terminal block and crimp the correct ring crimp and terminate to where their neutral is terminated??

Would this be acceptable?? (as where the cable goes through the wall it is chased in the other side)

Any advice is appreciated.

Thanks

Exposed cable: not an issue except for looking shoddy. Your trunking idea is fine.

Burnt neutral: cutting back and crimping sounds good.

HOWEVER: that looks mighty small cable for a 10kW shower!

Just thinking same, looks like a bit of 2.5 t+e!

Nah - the N conductor is stranded; but the CPC doesn`t appear to be - suggestive of 6.0mm

Iffy (dependant on route) for a 10KW load

It's 6mm clipped direct buried in plaster so it's right on the limit .

And is v.drop within spec? That`d be my main issue (along with Zs)......

Just a thought, could you hook a new cable onto that one and pull it down at all?

Doubt it as if you read #5 it is clipped direct and buried

Just a thought is all.

Thanks for the replies everyone. One last question on this one. Where sells 6mm single black by the meter as my wholesaler will only do 100m and I only need a foot at the most lol. Think Tom1 said something about screwfix/electricfix selling by the meter. Can anyone confirm this.

Thanks

go for tri-rated. you can usually get 6mm and above by the metre a lot easier than 6491

or use a bit of stripped 6mm T&E....

Ive got 10mm but no 6mm lol. Anyone know who sells it by the meter. I know Wilkinsons do but wont sell 6mm I doubt.

Thanks
