Shower supplied via 2.5 T&E

[soulman]

Unbelievable!!! Last week, bathroom refurb, the shower was removed an 8.5kw mira, it had been supplied from the pullcord in 2.5mm t&e, there was no thermal damage to the cable. The customer says it was there when they moved in, 8 years ago. I cannot believe it has not caught fire & there was no thermal damage!!!

Ha, seen this before a couple of times. Lucky the folks didn't like to take really long showers! Saw a shower spurred off a ring once, hmmmm.

I'm assuming the 2.5 T+E was installed to method c! Reckon the story would be different if it had been run through insulation!

Certainly shows the safety factors that were used when the 17th edition capacities were calculated! I'd also assume that their supply voltage was at the upper end of the scale...

I've come across this before and I've always wondered why they don't get nuisance tripping! and also is a shower wired in 2.5 on a 20amp breaker actually dangerous?

Not dangerous assuming the 2.5 is installed in a reasonable way... Can't see the shower working for long though

Nope, may trip regularly though


Best I've found is a shower wired on 1.5 flex spured from the ring, luckily the flex melted to protect the 13 amp fuse :lol:

hope my mate's hotel is OK. he's got 5 showers all on the ring final. oh, forgot to mention, they're power showers.

Sounds Polish to me ............POLSKI SKLEP

Struggling with 10mm T&E in a pvc backbox for pullcord is soo worth it when you realise folk are running 2.5 into showers

Had this once, melted a hole in the CU fuse carrier. Two previous sparkies couldn't find the problem!

The fuse at the ccu is only there for one reason! To protect the final circuit cable. 20amp and 2.5 fine!!

I had one recently, called out for a faulty shower.
checked power at iso switch, all ok, 6mm in, 6mm out.
Went to isolate at c/u and found the 40A MCB, but as it was a metel clad wylex I could see the cable leaving the fuse way was a 2.5!
Turns out their mate who 'has all the papers to be an electrician???' fed it from the disused immersion switch in the airing cupboard.
nice.

One that sticks in mind was my sister asked me check the wiring in her first house purchase in the 80's (that bad I did a complete rewire) shower was wired in 2 x 2.5 in parallel, problem was 1 neutral and 1 earth were cut off at the sheath, installer only needed the red "important" wire?

 

[R G]

I must keep a bigger stock of 2.5 t&e . I might get some shower jobs

 

[p11jor]

I have a 9.5kw in mine with a 6mm protected by 32amp breaker.....it's never tripped out and I have long showers.......you will find if you put your clamp on round it it will not draw anywhere near what the rating of it is hence no thermal damage!
