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:

Noticed this today, newish db install supplied with paralleled 10mm2 singles. Moeller unit with only one Moeller device, no blanks. The outgoing cables were just tied to nearby pipes and cables, or just left hanging. Looking at the small earth block, it is likely strands were cut out to make the earth conductors fit, they have very small terminal holes. There is 2 large AC units, 4X 3KW water heaters, 2x 8.5KW showers, a ring final and a lighting circuit connected here.

Cable and wall look unsightly?

No worries just cover it with some trellis and it’ll be right...

LOL, the old images are gone as well.

I just saw that as well. Kinda takes the joke away from an otherwise funny post.

Bugger, that’s a shame there was some funny stuff on this thread. Hopefully they get it sorted. ?

Working on a 1950s semi. Did have a dual RCD board. Upstairs and downstairs lighting circuits. Upgraded to an RCBO board and individually the lighting circuits started tripping. This is the two gang switch on the landing which is two way with switches on the ground floor controlling hall and landing lights.

More mundane, rodent damage, the cable failed the insulation test.!
There was more damage round the corner where the cable went up into the roof.
Now replaced with SWA.

To my surprise I discovered that Flexishield make cat-urine flavoured cables to deter rodents, probably easier to fit than SWA:

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

19 strand tails are now, finally, widely available so there is no need to be fighting with 7 strand 25mm tails.

19 strand is so much easier to install, the hard part is convincing my boss to buy the stuff...

 

[pc1966]

19 strand tails are now, finally, widely available so there is no need to be fighting with 7 strand 24mm tails.

Just a shame they don't offer SWA with 19-strand cores for sized above 10mm/16mm or so

Thats interesting, I wonder if they have reduced the amount of Copper.?
Just this afternoon, I was working on an 80 amp caravan hookup supply.
The original installers, many years ago, fitted a 100amp isolator and an 80 amp cartridge assembly (it used to melt the holder regular) now has a time delay RCD and a type C MCB.
Still upgrading the individual hook up points, as they are ancient. So I thought I would start at the source end first.
I expect it will trip regular due to overload by the campers, but its better than replacing a melted carrier every time, (they stink when burning). They will have to do without their space heaters at 2 to 3 kw at a time.! It has 25m tails, so was the usual struggle.

 

[pc1966]

No (at least, not from decent companies) as the 25mm is the spec, they just have it split 19-ways not 7-ways and that leads to far greater flexibility.

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)
