Name & age of this fuse box??

[Octopus]

Being doing a PIR today and came across this beauty - can somebody help me with its model/age etc?

I particularly liked the fact that there wasn't an earth bar and the earths had been twisted together, outside the CU and pushed into a choc block! Its a TNS system without an earth too, plus a partial rewire about 40 years ago has left a combination of rubber and PVC cabling too!

Believe you me, the insulation is falling off some of the cables and I'd rather rip the whole lot out!

Rite on mate...Ide do a safe isolation on it before even attempting to disturb it mate..looks a rite shower of sh1te......

It looks like a great opportunity for a couple of weeks work!

Almost certainly MEM. The case and glass front would make a nice display case.

Well lookin on the brite side.....Is it a fairly large place murdoch as i noticed that the c/u has a good row of carriers which for the date of this thing i would have thought suggested a larger install (for the times)?.........:tounge_smile:

Sadly not a big place, 3 of the fuses are no longer required, but the garage is "hanging" off on of the rings and the EFLI result was rubbish! So maybe a high integrity board!

Yes,only joking Glen

Having said that,it is not as bad as many I have seen and worked on,by a long way

It doesn't look home made to me,I believe there used to be a lid on these with hinges on the left,when closed the isolator was still accessable

The ceramic fuses and holders often cracked or the fuses would be split in half, with just the wire holding them together,so in that respect it has lasted well,also there doesn't appear to be any overheating apparent and the cable ends look sound,could do with a facelift though

I've recently took out something similar which was from house built around 1965. I thought it was 1940's, but talking to the next door neighbour, he said they were all like it from new, and built between 63 and 66.

I always thought the ceramic carriers had gone a lot earlier, but it appears not - it's like houses built in the late 90's still had rewireable fuses, rather than RCD protected with MCBs -there are lots of houses like that here (Leicester), probably as a cost cutting measure, as I know I fitted RCD CUs from 1996, and they were around before then.
