I guess sellotape is just immature masking tape.

That's not masking tape, its Sellotape...

Renovating...

Opened it up...

Clearly MF and airtight.

Was wondering about this...

Think it's some kind of emergency lighting thing...a grommet wouldn't have broken the bank, given it's a private health, fitness and sports club.

"CAUTION: This ~~installation~~ neutral link has wiring to two versions of BS7671." Innovative design, there... charred black on the bottom, modern blue at the top!

Solid neutral links often lead to problems (doesn't help if the terminal cage is partly on the insulation, either). Main switch was completely burnt out (luckily in the "open" position) and made crunching noises as I closed it.

Had to tilt my head to the right. Had this before with a Legrand C.U. wasn't loose.

may well be burnt contacts inside the switch causing excessive heat.

Could be. Though about 2mm of the solid link was clamped on the insulation. I think because there's no "give" in the solid conductors, it's not as forgiving.

Have to disagree with you there. No copper creep on solid conductors, although they can't carry as much current as stranded ones.

What I mean is, because there's no give, if the flat clamp cage is (partly) on the insulation, there will be very little force on the copper: the cage will be tightly clamped to the insulation. On stranded conductors, because they move about as you tighten the clamp (partly on the insulation), you're more likely to make at least some connection with the copper.

But I agree with you about the creep.

pirate · May 25, 2018

Yes, the creep is always a problem...Jimmy Saville for one.
Seriously though, I do understand creep in cables, but I was wondering...if a clamp is skewed, so is touching insulation and the copper, is a tight connection that way better then one which is making full connection with the copper but not very tightly?
I would tend to favour the former, as there would maybe be lack of movement, whereas in the latter, you have a bigger area to exploit arcing?
Please, don't hit me! I am genuinely interested to hear your views.

Steve, it looks like a storage heater distribution board judging by the 16a MCBs and 2.5mm circuits ? A combination of cheapy board, poor workmanship and a substantial load for several hours a day would certainly cause the problems found.
I think we'd be better off using metal boards to reduce the risk of fire in such cases. Oh hang on a minute....

Wilko · May 26, 2018

Hi Pirate - the correct mm2 contact area is critical to avoid heating and the pressure from the clamp ensures the contact is maintained over time etc. Without both the result is an unpredictable failure, imho

Working at height, how could that be dangerous?

telectrix · May 26, 2018

apparently there are no trees in the area, so this tree hugger has retrained in 5 weeks to become a fully qualified (domestic only) chimney hugger.

Someone needs to explain to them the difference between a mechanism and a structure

. Or they'll learn it on the job at some point unfortunately.

This video montage contains some truly shocking examples of extremely poor 'workmanship' and gross stupidity. As the 'music' in the video is quite atrocious I would recommend that you watch with your speakers turned off.

telectrix · May 26, 2018

just wonderoing which is the worst. the music or the video.

It's a very close call.

A fan 'isolator' found during a periodic inspection. It switched the fan on and off but left it live. Perhaps it was some attempt to wire the timer fan into a circuit with no switched supply.

Carrying out some alterations in a new office building, found during testing, the terminals had been seriously overtightened, I assume with an impact driver.
