Poor termination or overload I think. Speaking of professionalism you are always so calm and explain issues to the client as simply as possible so they understand. There is no point talking about esqr or DNO to the average Joe, might as well be speaking Latin.
It appears that smart meter installation is a bodge job. He should have changed the tails instead of just placing extra insulation over them into the meter. It's likely he didn't re-tighten the live tail into the cut out properly (if at all) and then you have a loose connection overheating and sparking off. The two fuses off one supply like that was just a way to split the supply with individual fuses without installing a whole new supply head for the other meter.
Could very well be a loose connection but you can get something called phenolic degradation sparky ninja/E5 have a good video explaining what goes on It's quite an eye opener. ruclips.net/video/1u38ukhGi3o/видео.htmlsi=Wz0-b8L_7w2MtFMi Down this way WPD (now national grid) have started carrying out cut out changes on any of the old phenolic plastic (bakelite,black plastic,etc) cut outs to the newer grey GRP style ones
You would be surprised just how many of these videos where they are explaining that you shouldnt touch such and such as its live while waggling their fingers at the area while explaining to the camera
Looks like the property had single phase supply prior to be being split into flats so the existing supply was split into two, not easy to bring another phase in as that would mean digging up the road etc and no real need
Thats kinda the norm in most of the world, they just supply everything with a thick gauge single phase wire and you split from there. I've seen faaar worse bodge jobs in portugal
More investigation should have been done ….. and why has no one else spotted the other big issue in the video …… it’s two smart meters for two flats ????? Wrong …… Henley blocks on the left have another feed going off somewhere else …. This makes the burnt 16mm red cable not suitable……. It look to me like someone has bodged an electric car charger into the system …. the CT clamp on the red gives it away …… all main tails need replacing and this should of been told to the customer because they have been compromised also no protection from block to charger ….. you need to see customer about doing a full investigation as to why 3 sets of main tails and it’s full power consumption delroy that’s a phone call you need to make to your customer …… DNO won’t do anything
I have a weird setup at home, single phase in and then two main fuses with one only connected, house was never two flats then converted back to a house.
Looks like a bodge from when that building was split into flats, combined with poor installation of smart meter. In an ideal world, rather than just repair it, I'd put each flat would be on its own phase, but I doubt either UKPN or the leaseholder would be happy to pay up for that.
100A 240V Some domestics have 100A 3 Phase though! This looks different because it is a HMO or flats. The DNO is responsible for the supply up to the cutout after that it is the Supplier until after the meter it is the consumers. The supplier will argue that the cutout tails are the DNO's but if a new supply is put in we stop at the cutout and leave that without a fuse in unless there is a meter and it is tailed up (in which case we would connect the tails into the cutout and fuse up.
Max power would be 23kVA for a 100A single phase service, 14kVA for a 60A single phase service. While you could exceed that, eventually the DNO fuse will blow, or your meter will burn out.
Right call to call UK power network, not to touch there main cutout.
Did you charge him for your time
I think he did it for free
Single phase into feeding 6 flats in 2 blocks what we were rewiring and it got changed to 3 phase when we reported it not being safe
That bit of ply wood would come in handy to keep the potential fire going😮

That’s what I thought he should done new tails was trying to zoom on the tags to see if he even took the cover off the incomer to tighten

Great video as always :)
Your hand is getting way too close to that melted tail when you are touching the fuse explaining what is going on 😅
You would be surprised just how many of these videos where they are explaining that you shouldnt touch such and such as its live while waggling their fingers at the area while explaining to the camera
send the customer up a stepladder behind the front door that's ajar. what could possibly go wrong 🤣

Its an Eco Eye energy monitor thats using the CT clamp
Just a note did you charge customer for call out ? Thanks
Ofcourse
Fuel, time, professional advice
I would, still his time getting out of bed, driving there, professional advice to the client

great video great work

How about the bottom of the switch fuse and the other grey tails? They were burnt quite badly but don’t they belong to the customer?
Good video-🎅🏻
I remember that video
Whats the max power allowed for domestic single phase in the UK?
100A 240V Some domestics have 100A 3 Phase though!

What i'd of dealt with that there and then no need to call UK power network out at all.
Needs reporting so they can change the cutout
Seen it all before
Let's go 😊

Hmm it looks very suspicious to me
