IEC60269 cartridge fuses.

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?

    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 ...
