Old cut out fuses

[Adam Smith]

Evening all,

I am looking to get hold of a 40 amp cut out fuse to replace an existing 60 amp to provide adequate protection to a supply cable. I bought a BS1361:1971 fuse thinking it would be the correct fit (22mm diameter) but it turns out its about 2mm too wide to fit in the carrier. The fuse carrier and head do look very old so was wondering if fuses that are slightly thinner than the standard cutout fuses are still available and if so, where I get hold of one?

I was thinking of running 16mm tails to a wylex switch fuse and downrating there if I have no joy with the main fuse, but I've not factored that in to the price and would like to avoid taking a hit on that one. Also there is the worry of getting on the wrong side of the DNO if they catch wind of me tampering with their equipment (although it looks like they last set foot in there in the 60's!)

Thank you

Obviously the DNO's equipment is just that, The DNO's, so leave it alone. Fit a switch fuse, take the hit on the price and put it down to experience.

Ring the bloody DNO and tell them that supply tails or in a unsafe state. They will put a new cutout and 20mm tails in. No charge for an domestic building if the install is old enough and they will also change the meter to a smart meter if you live in the right area and have the right DNO. So if you or mad then you can put what ever size of fuse you like in. Or ring them and and ask to talk to an engineer and ask them?

20mm? You sure about that? I have never come cross 20mm, well other than where espmeone has joined two 10mm together, the last I knew it went 10mm, 16mm, 25mm, 35mm

Sorry 25mm tails they don't do 16mm,s any more it was late and all that popcorn when to my head

Why hasn't anyone asked 'are you an ELECTRICIAN' yet?

When I was at college, we were taught the difference between BS 7671, and EASQR or whatever it is now.

Only our responsibility AFTER the meter.

So, my advice to the OP, call the DNO, and at least ASK the question.

DNO out to upgrade mine,in the morning...surly gentleman inspected today,could'nt get a smile out of him,tried to involve him in a bit of neutral-fuse-banter,and he said "It'll have been linked out..." no,i replied,it's fused,"How do you know?" he replied....long pause..."X-ray machine?" i quipped...not a glimmer...Anyway,he put a seal on it,which is the first time it's had one in forty years :icon12:
