I would be very surprised if this is a separate L & N, would probably be a Feed-in and Loop out to the next customer.
Has something been moved? I cant see how that head was ever fitted to the original backboard.
@WorkshopChris the crumbly chip board backing board is like that because I used to leave the door open to read the meter ,
Gonna up grade with a bit of OSB
Don't panic !Not removing the back board just the small angled piece that the fuse block is connected too !
I can second that advise that head unit should not be moved or subjected to any movement.Be careful otherside of that fuse will 1000a +
in the past I have moved a few peoples meters on to different walls and shortened the cables while live made me some fast money and saved the punter time and money ive done a reasonable amount of live cable jointing years ago just get well tooled up with insulated gear rubber mats dry day and a face shield . I wouldn't recommend anyone doing it diy unless you have a death wish its ok 3 phase 440 v but I wouldn't want to touch anything higher without proper trainingI can second that advise that head unit should not be moved or subjected to any movement.
If this is DNO equipment and not part of a privet landlords distribution network, the upstream disconnection current could be huge.
I have seen a poorly terminated split concentric cable clear its own fault and that was on a 100a supply the thing just kept arcing until it burnt its self clear.

its even more dangerous doing undergound joints live at 11000 volts a cable jointer was doing one down a hole in the road from us and it blew up and killed himI have absolutely never moved meter tails with big rubber gloves on to avoid pulling the DNO - not something to be undertaken, but hypothetically if one did, one would certainly want to think through the order of operation very carefully as it would be very easy to get stuck with cable in hand and the required screwdriver 3 feet away....
440 is serious enough, and as for those crazies that dangle from helicopters playing around with 36kv, I’ve never understood how they don’t arc out with those massive brass balls they have...
Just a big breaker going, if your next to it, is bad enough, with out jointing it live!its even more dangerous doing undergound joints live at 11000 volts a cable jointer was doing one down a hole in the road from us and it blew up and killed him
