IEC60269 cartridge fuses.

Sparkingchip:

I have just completed a job and installed a new fused main switch upfront of the tails.


Three fuses were supplied 60, 80 and 100 amps all IEC60269 and I have installed the 80 amp fuse.


All done, however I am now looking on pages 356-358 of The Wiring Regulations BS7671 and surprise, surprise, I cannot find them listed. Issue or no issue?

"The IEC standard unifies several national standards, thereby improving the interchangeability of fuses in international trade." Apart from the strange physical shapes and sizes which seem more "industrial" than "domestic."

I agree with Graham - as I understand it BS 88-3 is dual numbered with BS HD 60269-3 (which is itself the UK implementation of IEC 60269) - it is a BS 88-3 fuse (similar to the old BS 1361 ones of yore).


I'm a bit surprised at the 60A one though - I thought they moved over to preferred numbers when the old BS 1361 was dropped - so I'd expect it to labelled be 63A rather than 60A.

"Preferred" is not the same as "defined", "required", "mandated", "only", etc.


The "preferred" values of BS 1362 fuses are 3 A and 13 A (Clause 5.3.2), but it doesn't stop BS 1363-1 calling out other values ...

Sparkingchip:

It looks like a BS1361 also known as a BS88 to me.


All it is is a bog standard fused main switch like this https://mastertrade.co.uk/catalogsearch/result/?q=Click+DB750+Switch+Fused+Main+100A


It will be easier next year when everything has a UK approval mark on it ?

Yep I have seen and handled  those switch fuses. My only concern really is the quality of the cartridge fuses. Are they really made to any required standard? They look "cheap" to me. I prefer to use genuine branded cartridge fuses such as Lawson etc.
