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

What did is say when you pulled it out.

It depends on what is fitted

Obviously I haven't pulled it out!
We can never tell exactly what is fitted because of the seals, so my question is thus; what do I enter on the Characteristics of the primary over current protective device? Has the the designation BS1361 type II fuse been super seeded by a BS88-3?

You will have to state Not Verified you can't guess what is fitted.

Write what it says on the fuse holder BS 1361 type whatever a or b we can’t be second guessing what might be inside but you can call the DNO for supply characteristics and type of fuse installed if you want to waste an hour on phone calls

On ours I think the type was moulded into the plastic cover, you might need a torch and magnification glass to see it though.

As Westward has said, Not Verified.

I don't understand why you would quote what is written on the fuse carrier it could contain anything.

My bottle of Bells Whiskey says blended whisky 40 %vol, her indoors Focus is supposed to have a 1 litre engine, and my glass is half empty. I don't doubt them, or my eyes.

May contain nuts.

Are you not a member of a scam? Some suppliers will let scheme members pull the fuse....

Love it, more clear cut guidance from the electrical hive mind.

I'm in the "what's on the carrier goes on the form" camp but see the the other paint of view.

Now I'm off to find my tweezers, I've got a splinter in my arse.

If anyone finds a definitive answer the please PM me

When I had the opportunity to exam the fuse, I'd record that, otherwise it would be what was documented on the fuse carrier label. Without that supplied information, I'd put the N/V etc thing.
