What is the BS number of the DNOs cutout fuse?

spud1 · Apr 30, 2019

Hi,

Is the DNOs cutout fuse still a BS1361 type II fuse or has this number now changed to BS88-3 ? (For the purposes of entering particulars onto certification)

Thanks in advance

I tend to record the information as "labelled as" and then specify what is on the carrier. I try and provide as much reasonable information as I feel is useful.
However NV would be the most appropriate designation even though it is less informative.

If the fuse in the carrier has not been replaced in the last six years then it is going to be BS1361, if it has been replaced then it could be BS1361 but, certainly in the last few years, it should be BS88-3.
The standard designation does not change for a specific item over time but the standard may be withdrawn or superseded. e.g. isolators to BS5419 are still isolators to BS5419 even though a modern isolator would be BSEN60947-3.

might say 80A BS 1361 on the carrier, but for all we know it could be a 3" nail with the head cut off inside.

So, how about cutting off the locks, looking at the OCP and then crimping on some more locks after reinserting said fuse?

Why cut off the head?
Too much faffing around.

Current use fuses are BS88-3 but there are obviously plenty of 1361 out there too. Most new connections are fitted with 80A fuses but the cut out fuse carrier is rated at 100A.
