Weird fuse deployment

[kingeri]

I was doing an EICR today on a bog standard terraced house, and as part of that was checking the fuse ratings in the boiler FCU etc. (always do this as often people can't be bothered to swap out the 13amp fuse). Anyway, found the boiler FCU was fitted with a 1amp fuse, a spur for a built-in computer desk area on the landing was fitted with a 7amp fuse, and a lighting spur in the loft was fitted with a 2amp fuse. The FCU on the landing for the towel rail in the bathroom was fitted with a 10amp fuse. Nothing actually wrong with the ratings as such, but I did find it decidedly non-standard. Anyone else seen this kind of thing?

The fuse protects the cable....................what were their csa's?

All kinds of cowboys get involved in stuff, I've found all types of sizes all over the place from standard 13,3,5 etc to the glass bodied 1.25 etc.
Think some people use what they can find if they ever blow.
Best I ever found was a paper clip sure it's been done loads but just outrageous to find it.
However if anyone knows the current carrying capacity of a paper clip please let me know

How thick was it?

Lady said the fuses have never been changed since installation. Just don't really see the point of using anything other than 3 or 13! Or occasionally 5. Sorry if nobody cares, just wondered if anyone could explain why this might have been done. It's almost as though someone has tried to match the fuse rating as closely as possible to the current draw expected.

Selective reading or what?

or did you miss that as well?

Any reason why you're being a bell?

The CSAs of the cables were not an issue, they were adequately protected by the fuses. If anything, the fuses used were that bit lower in rating than what you'd normally use.

You started talking ****e I just joined in mate to keep you company!.
The csa's of the cables are an issue if they are rated 'less' than the ocpd............hence my question!!

If,as you now state,they are not an issue..............why ask in the first place?
Won't respond again.............good luck mate.

 

[kingeri]

I didn't ask anything about cable CSAs or even mention them (that was you), I was asking about the fuse ratings themselves and if anyone had encountered them.

Seems to me you are the one with 'selective reading' or at the very least some kind of attitude disorder.

Wow this thread got weird...

Nope ive never come across that
Only 3,5 and 13amp fuses

I know you didn't but if you look 'outside the box' you'll see that as long as the fuse rating is below the ccc of the cable you'll probs be fine...........hence my question.
Which was................why be bothered about the fuse ratings if the cable ccc is ok.
The fuse protects the cable not the appliance.
But you know that already.

Ok third party stepping in from neutral side.

44allan u mention csa's first.

I think ops original statement/question is just whether anyone has come across non standard/uncommon fuses being used.

I know what you mean, but I was simply asking, out of general interest, if anyone has encountered 1, 2, 7 and 10 amp fuses in a domestic setting. Nothing more, nothing less. If, in your view, that is not an interesting topic, then feel free not to comment, but please don't have a go at me just for asking. I fully understand what fuses are for in a plugtop or FCU, and I understand the relationship between the CCC of the cable and the fuse rating, and that is not what I was asking about. If you read back, you did indeed seem to turn rather unpleasant for seemingly (to me at least) no reason.

Anyway, as the use of (to me) strange fuse ratings is seemingly of no interest to you, let's just leave it at that.

I apologise for any offence I have caused, and hope there are no hard feelings (there certainly aren't on my part).

Phew.
