Right ... Just been nudged to set this up by Paul.M and sounds a good idea following recent threads I've done in the Arms..

Rules....No Offensive material... edit if required before posting as this is the public arena.
Anything to do with the trade or in and around it ...H&S pic's welcome.



I've posted this a few times and this is at a mates house following a kitchen refirb several yrs ago. mg_smile:

No they haven't reduced the amount of copper, they wouldn't be 25mm if they had.

They have increased the number of strands therfore made the cable more flexible.

That is not the correct soloution to the problem, either a reduction of the load or a larger supply is required, changing the fuse for an MCB will not solve the problem.

By fitting an MCB in place of the fuse you have made the discrimination (selectivity) worse. Also the regular overloading of the MCB will cause the thermal element in it to suffer damage and probably cause the MCB to trip more readily or cause it to fail completely.

I dont really see a need for it, the overall flexibility of the cable won't be helped as this will be governed by the steel armour.
As long as you use decent switchgear and good installation practices then there is normally no issue working with 25mm or 35mm (50mm and up is 19 strand)

I forgot to mention, the reduction of the load was another recomendation I made last year, so they have cut the big rallies down to fewer vans and an option for no hook ups camping areas.

A couple from the same house.
Customer asked me to look at the shower switch. “It tripped the breaker, so I changed the switch cos it looked a bit black, but the new one tripped it as well”

10mm into a 1 gang box, and too much cable. I had to cut 3” off all cores to make it tidy.

And I was driving away down their lengthy driveway.... there’s 7 or 8 of these lights. And I think that’s 2.5 t&e

Well at least the CPC was doing its job!

 

[littlespark]

That wasn’t the only black mark. The outgoing cable to the shower was pressed so tight together, there was a pressure fault between l and n

i like the way that outdoor T&E blends seamlessly into the background...clearly a case of aesthetics winning over good practice...
I can't see many clips...they are obviously so well disguised too!

 

[Dustydazzler]

Looks like 1.5 to me

There were clips.... about one every metre or so. I wouldn’t be surprised if the lights were stuck to the wall with silicon.... not easy to drill into that stonework.

Christ, what a day.
Bathroom first fix. In the dirtiest loft with about 20 inches of black insulation.

Doing all my tests at the supply end at the end of it. Spot a cable hanging out of a old meter, just cut off. Still live. Been like that for over 20 years.

The kitchen was done 5 years ago, the guy who did it didn’t notice the obvious danger slapping him in the face. Also the dopey -----, disconnected the TT rod And left the cable floating in the mains board, cracked out poorly the service head earth bar and did a DIY PME. Now, I know this area and PME isn’t available, hmmmm. Turns out Zdb with bonding connected is 10.2 Ohms. True Ze of his DIY PME >999 Ohms. So the only path to earth was through the Water and Oil bonding he had at least installed.

Didn’t even bother labelling his own new circuits in the classic proteus board that was installed.

I’ve had a bad day.

That’s a song by REM
“It’s been a bad day, please don’t take a picture....”

oh. You did.

I have got used to fighting with SWA, its 25mm tails I dislike, it nearly needs a blowlamp to make it bendable

Shhh, don't tell anyone, there's stuff called 6381Y. Needs ferrules, but doddle to work with. Biggest problem is that very few places have even heard of it, let alone stock it.

Think CEF list it, I've only seen it in DC colours though.

DC colours are either brown and blue or grey and blue dependant upon polarity.

As an aside a lot of DNO/suppliers don’t allow the use of tri-rated cables as their equipment terminals aren’t designed for fine stranded cables even with ferrules.

The 19 strand tails are a lot easier to work with.

 

[Zerax]

TLC stock it too I think.

CEF only do Grey & Blue. I ended up buying direct from Cleveland Cable who do all the standard colours.

Useful to know. What are the issues ?

Useful to know. What are the issues ?

Ferrules are only made of very thin material and most DNO/suppliers terminations are designed for the thicker stranded cables, at a guess the screws damage the ferrules allowing fine conductors to splay out causing loose connections. Also the ferrule slightly increases the size of the conductor so some may be very tight to get in without 'modification'.
