Looks like a bit of a mishap in that surface box, with the black smoke marks. Wonder if the sellotape failed at a time lol

So I got called out to a tripping breaker last week. 30A old Wylex push button MCB. Client had repeatedly re-energised and reported it stayed on for a while. This is what I found in a back box...
After what I thought was a thorough walk round and some testing, it looked like there were just loads on the circuit, I did energise it whilst clamping the supply... 50A!
Wasn't able to restore full service but went back yesterday and this is what I found during my investigations:-
TT System with a fully functional 100mA upfront RCD which had been disconnected, but left in the on position... client was wondering why it didn't trip when this fault occured.
Ring final circuit with a leg that had been deliberately cut to break the ring with still connected live cable ends left uninsulated in a back box. The circuit was left on the 30A breaker.
Another socket had been taped over with parcel tape by the last 'electrician' to visit because it wasn't working.
When I left, the ring appeared to be in good order with good end to end continuity, the topology appears to be correct (some sockets were a bit high on the R1+R2 front but there is a bit of damp problem - that I suspect has been caused by people rendering inside and out with a strong mortar mix instead of lime render), IR is a bit low at around 2.5-3Mega ohm, RCD has been restored and tested (fully functional) and as far as I can tell all socket outlets have a functioning earth which is a major step forward from when I arrived as I found several with loose or non-existent connections.
The worst of it is, as best as I can tell, it was left in a bad way by a local guy who as far as I can tell has never been registered with a scheme but has been advertising for years offering the full compliment of domestic electrical services. It's not the first time his name has come up when I found some bad work.
Had another case the other day where I was moving a socket outlet. Started testing and shocker, the results were in some cases not at all like the certificate (they had a CU change back in June)... all circuits recorded having an IR of 200 Megaohms. I only found one that had anything like that, and on one half of the board, none of them had an IR of much over 3Mega ohms. And why was the board change sold to them? Because plastic boards are now illegal and they needed RCD protection for the lights in the bathroom (true) and their new mixer shower (true). But given they already had RCD protection on the socket circuits, both could have been supplied as spurs from the socket circuit... but hey how, plastic boards are now illegal so I can see a lot of board changes coming my way!!! FFS
Again, in that case a name came up that I've run across before, again in relation to some dodgy work. Does my head in!

Nice pic. Very appropriate considering it’s BBQ season. 
Appreciate I may have put off anyone coming round to my place for a BBQ

Here’s a double socket I installed a few weeks ago.Nice pic. Very appropriate considering it’s BBQ season.
That slight charring on the two top lefthand terminals needs lookin into...

There’s quite a knack getting the termination just loose enough to get the correct arc. Takes years of practice to become competent. I hear that TLC are bringing out some lemon and coriander flavour earth sleeving

I was on holiday last weekend barbequing half a dozen lovely juicy switch fused outlets (sausages) on our little bucket we use on caravan sites.... when a hungry seagull came and nabbed one off the grill.
Bas***d!
Bludi seagulls!
One did the same to me recently...tore a chicken breast off the BBQ, and it was stuck on quite hard...how it stood the heat I do not know.

It's nearly always the same when you have only one day that you can do something on a particular day . Something to to with that chap called Sod.

Workmate sent me this photo, he had a problem with a drill battery. The white is powder from the fire extinguisher.

@Dustydazzler . Yes when they go off they take no prisoners . Lead acid batteries are very dangerous when they go up.

It was a lithium battery pack.
Similar thing happened apparently, it was just sat on the floor and started making a sizzling noise then smoke, fire and bursting cells.

When Li Ion batteries go they do it in style. This is why I never buy cheap batteries from the internet, less chance of genuine ones doing that, but there's still a chance.

Yes I know, I was just saying that lead acid go off spectacularly , combined with the added danger of acid and hydrogen.

- Lapsed trainee ( was doing stage lighting 30yrs ago),
+ father of Trainee -who has recently jacked it in !
It is his, the battery, drill and charger were all bought new from a registered Makita dealer, about 2 or so years ago. The batteries would likely only be recharged when flat. Makita requested the mess be sent off to them, which it has been, (presumably so they can hide the evidence in the bin!) so they can investigate.

Yeah mine was a li-ion, had 4 as part of a set of kit, the batteries were all the same age never been that roughly handled and only charged when needed as there was only me using them. This particular one sounds very similar to what happened to mine, a plumber mate had it happen too drilling a double joist with his Makita, he lost all the hairs off his arm as a result!

I have just repaired the gearbox on a mates Makita impact drill . I have to say I am not impressed with the quality compared with what they used to be.

I have replaced a motor in one of those too.
But it was down to abuse . They are easy to work on.

Heard of this a few times. No idea why people buy the ebay/amazon fakes. The genuine ones don't cost much more.
My Milwaukee 5Ah 18V are only £55 where fakes are about £45. The genuine ones last for years with no issues. Not had one fail yet.
He paid full price, and has the order receipt, which clearly states genuine Makita battery on it.
