Joking aside that flex would probably pull 26a without too much trouble

I have seen an old JW video showing 1mm/1.5mm solid taking about 50a before it started to bubble and smoke

Pointless is obviously just my opinion, but I do have a particular hatred of labels that nobody will ever read/will ignore, aren't required, state the obvious or just make a neat job look messy.

You are not alone.
In one building I regularly work in they have
-a locked door with a neat, clearly legible, label on it identifying it as the electrical intake. Seems pretty self explanatory yes? No, some muppet with a clipboard from head office came round and insisted that this bright yellow 'warning high voltage' sticker be put on the door.
-doors opening into a cable riser on each floor, no DBs or anything else in there, just a couple of trays and some trunking, the doors are kept locked and everyone who needs to know what's in there knows. Along comes the clipboard wielding womble and now there's these hideous (wonky) yellow stickers warning the world of the high voltage inside.

I hate that warning label, it's the worse one of all the ones we're supposed to add!

At least the others make some sense.

Should have gone with the "stairs can go down as well as up" option

More useful than the wiring colours!!

When you combine two things, such as a spoon and a fork, it's usual to create a portmanteau such as spork (although others create it the other way around as foon).

Since this is a clever way of combining a fork and a bracket perhaps it should be called a Fo'cket.

The guy obviously just thought Fo'cket when he did the job!

First of all, I hate labels! I do have to satisfy a "spreadsheet" mentality however...
and yes, I hang my head in shame for using sellotape but that's what was to hand...

On the fork thingy, does anyone remember "Splayds"?
I thought they were a 70s thing, but apparently they are still on the market...

That fire exit pic tho...o_Oo_Oo_O

That door needs a sign on the push-bar such as "fire exit, push to exit"

Or else no-one will know how to use it or what it is!

Very nasty little widowmaker found above a ceiling. One klik rose was perm for emergency, other was switched supply from PIR. Previous installer had bridged the lives together in the fitting in the switched terminal - so the emergency side had never worked anyway, and pins of either klik plug were live when the other was unplugged.

In a school. Honestly they're the worst for it. Big "maintenance" firms smashing the remedials out with so many layers of people that there's basically no accountability.
 
I have come across this several times where a big bunched bundle of 2.5 red / black singles are being used as tails...
at first I was cursing the badger who installed such an abomination.
but after My initial shock horror I kinda had to stand back and admire the handwork.

In that picture its quite clear its a split concentric feed rather than a big bunch of singles.

I have resorted to using a bunch of 2.5 singles as an emergency measure once in the past, it was all I could do at the time to get a pub through the evening before fixing it the next day.

A worthwhile cause I feel. Should be covered on the regs.
 
Periodic in local restaurant, guy payed 5k for this shop refit, left all the old 1200 x600 fittings above false ceiling still connected but tubes removed.

Yes it got worse there was 415 volts at the Emergency lighting, when they connected the 12 gang light switch up they got there wires crossed sw/perm.
 
Here are a couple pics of a VFD at work. A lot of wires were from before a drive retrofit and went to nothing. Wire nuts on the end of them. Before and after.IMG_3065.jpgIMG_3066.jpgIMG_3075.jpgIMG_3076.jpg

Never ceases to amaze me why people wrap an unenclosed block connector with insulation tape, like it makes a difference.
I was particularly impressed with the use of g/y tape for the twisted cpc’s. You don’t see that sort of attention to detail these days....real quality.

Fantastic job today going to fit a new control panel, PME the sign indicates. No earth available for me to connect to is there. Called out DNO who turned up to tell me "yes it PME, I can tell by the cable and cut out". "Thanks for that how am I going to connect my earth to it"? "That's not my problem the earth is there". "Yea awesome thanks for that, how am I going to connect to it"? "Well I could put an earth terminal in if you want but you will have to pay for it". "Thanks that what I called you out for I need an main earth terminal to connect to".

Got that sorted then go to remove old panel found this !IMG_0860.JPG

Yep no flipping earth at all through the lot that earth core being used as L2 is about as close as it gets. F00k it (I don't carry enough spares to sort this out) pulled the fuses and left for the weekend. I'll go Back Monday as I've got some great contractors booked in to replace the lot from the cut out on.

Isn't that the type of cutout that has a little knockout in the side of the neutral section to connect the earth to?

I think the right hand fuse has to be removed to gain access to the screw that holds on the cover over the N-E terminals even though you can knockout for cable access from the outside of the head.

you can't remove the cover for the neutral/earth without the third fuse being removed the neutral cover also has a seal through it. That's why I called them out. To be honest after a half hour conversation I just gave up the chap clearly couldn't understand what I had an issue with. I'm very fortunate that we have instant access to the DNO and they will always come out as a priority, unfortunately it doesn't include any guarantee of who they send.
 
Was called to investigate no power to a DB after some recent work the board was changed by others and just some photos I took walked away and passed back as not getting involved in this attempt 20200227_172444.jpg20200227_171958.jpg20200227_171924.jpg20200227_171939.jpg
 
I don't think I would have used that board for that task.
I agree like I said couple of photos for the job sheet and tools packed up and gone.

I visit this site frequently and previous was a board not dissimilar i suspect it was upsold with a recent refurb.

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. m.jpgm1.jpg

Cable and wall look unsightly?

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

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.DSC00646.JPGDSC00647.JPG
 
19 strand tails are now, finally, widely available so there is no need to be fighting with 7 strand 24mm tails.
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.

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.

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

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.

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.

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.
