What is the BS number is for this old DNO Crabtree enclosure?

[Too_Wired]

Can't see it being anything other than 3036 with fused neutral, although tails replaced (within the last 40 or 50 years).
Definitely a case for DNO. They will change it and renew the main earth connection. Better be quick though, before it topples off the wall.

Better off if you contact DNO and explain the situation fully.

Mucho appreciated for the feedback

Just noted your request to contact the DNO. It's already underway and the landlord has been asked to advise them of the leaking tar from the enclosure. This installation has all kinds of Gremlins, but I suspect the issues stem from the various/random alterations done over time. Thanks again

Thank you to everyone for their feedback

If you want to see why the DNO guys wear the arc-flash gloves and face mask when doing anything on supply fuses this video shows it in action:

Those guys were properly kitted out so probably OK, but I suspect their trousers fared less well!

Under no circumstances open it. It may well predate a British Standard

Predating BS88 is a challenge, just the low number tells you something about the age of the fuse standard!

From memory it is something like 1921 it came out, so possible it predates it but you know what curiosity did to the cat.

and there is every chance it contains BS3036 semi-enclosed fuses, when I say fuses it may well have one through the neutral. It will almost certainly be replaced.

Very likely. Certainly a "do not touch under any circumstances" item!

A check on BIS shop finds this withdrawn standard:

Electric cut-outs for low pressure Type O for ordinary duty with working currents not exceeding 100 amperes
BS 88:1919
Withdrawn 30 Dec 1918

How a 1919 standard can be withdrawn before it is issued is a mystery!

True. Even BS1361 dates to about the time we started using PVC cables in the late 50s/early 60s. There's still a slim chance that the cutout is not quite as old as it appears and there's a cartridge fuse in there.

I don't believe that meter is contemporary with the cutout either and if the cutout is as old and dangerous as feared, how would it have not been upgraded at the same time as the meter since they would have had to isolate it?

Perhaps if OP is there when the DNO removes it (unlikely I know) they could take a picture to satisfy our curiosity?

Probably 30-40 years ago folks were less safety conscious, and hardware like that 30-40 years younger as well!

I know a friend who has a cut out that is similar and almost certainly a fused neutral. But there is a whole lot of issues why I would not get involved there, as the property needs rewired as well as the DNO in to sort it. Unoccupied for a few years, think along the lines of Miss Havisham

I think your spot on there.

Exactly like one I had Western power out to.

It was fuse wire through both line nd neutral. it took 3 guys in 3 western power vans to discuss and desided to remove.

forst guy said it was fine, I disagreed pointing out the fuse wire to neutral. then his supervisor came out then a more experienced engineer came and did it.

Wow...!! The content on the video near the point of the explosion is really annoying but the message is clear !!
