Yes using a suitable low current DC capable clamp meter

I had exactly that arguement when my daughter moved house following divorce and her ex created so much hassle I had to get the alterations 'certified'. There was a 32A circuit for a hot tub on 7/0.044", when they moved in it fed only a DSSO in the conservatory from the original isolator...

To use on the green phase!

Agreed Also this would be betterand this would have been easier

And the easiest thing to fix it may be something like writing: "earth wire fitted" rather than the actual truth of: "earth wire existing".

Yes but... Although not conclusive, while listening to the traced tone, shorting the end of the cable will make the tone disappear but only if the cable is continuous. Such 'knocking off' as we called it, was the standard method in BT.

OMG Thisn is something I've been saying from the very start and everybody seemed to poopoo it

I'm sure there are numerous variations by now anyway.

I see the tester in the earlier pic and believe I identify it as 'one I've handled' and seriousely don't recall it as a count of 10 by the perceived gap, only to 9, however this wasn't recent but initially the error went unoticed. Some of the early testers of course only had 8 LEDs in which case...

But is the gap for 9 really that obvious when it happens? The only reason I ask the question is as always the experience.

When they are a great didstance apart and it ran 1-2-3-4-5-6-7-8 on one side and 5-6-7-8-1-2-3-4 on the other how many would instantly question it? On the unit I have there are 4 leds marked 1&2-3&6-4&5-7&8 Flashing green = good, red = flipped, out of sequence = out of sequence, dark = one...

Hah hah yes. we had a job some 25+ years back where a rack had been removed and the cables reterminated in another rack. No idea what skills the guy had but he had managed to terminate them incorrectly - the lights flashed in sequence but out of step with each other. The kit we patched to it...

Oh yes very true but now kits as boards are now so cheap from alibaaaahhbar its often cheaper to by a kit just for the components, a recent example being 'electronic dice kits' at 17p - 7 LED's (choice of colours) 555 & 4017 with sockets and R's, C's, push button and PCB, I made several into...

Yes these have been discussed before, I got mine at age of 9 (following broken leg and laid up) and I'm also 70. Electronic Engineer 8 and Add-on 20. How many transistor legs did you break off? I saw later versions had a rubber boot for each to protect them to some degree.

My biggest headache has been catering vans requiring hook-up, invariably they pull way over what they request.

The story is the DNO kit was moved a little over 10 years ago, when the granny annex was built and coincident with both split load boards being fitted, so I wonder why it appears to be looped, the other properties seem to have indoor services.

Yesterday a customer lost all power. At the time they were having 2 showers using instant heaters and a selection of small loads: TV, lights, Christmas lights router etc. DNO fuse marked as 60A and a B63 MCB feeding T&E to Henley then CU and second T&E to granny annex. Apparently they didn't...

Years ago a colleague 'borrowed' 50m of 0.5mm² 3 core flex from work to cut his grass (before a pedant mentions it; this was for an extension lead for his mower) When he got a colour TV he positioned it differently in his room due to the increased bulk - we heard all about this at the time it...

I have repeatedly demonstrated to a local churchs officials how easily these ****ing things cause problems by partially inserting the earth pin upside down then giving it a thump which typically pushes it right in and snaps off. Each time they go round and dispose of them but within a few months...

My personal assessment of all of the options is the cassette style are aweful unless fully unwound everytime they are used, otherwise they wind irregularly. Yes I have a few on open frame style reels (~20) but the vast majority are loose wound. Having several Km of longer cables (~10 to 200m)...
