Oven & hob on 13amp fused spur

It is not compatible with fuse ratings on a consumer unit, where you will not find a rating less than 5 A.

Only in the UK is the minimum normally 6A for MCBs - elsewhere lower ratings are common - e.g. the French normally supply their control circuits and low power equipment (e.g. bathroom fans) from a C2 MCB. But then they don't have the option of a 3A BS 1363 fuse in a FCU, so it's all a bit circular.

 

I presume the reason for this is to "officially protect" the IEC C14 plug, which is rated at 10 A. However I would not be overly worried if a 13 A fuse were fitted. The fuse is to protect the lead and the connector at the other end, but not the monitor, which should have is own internal fusing.

Indeed and a 13A fuse will likely easily protect the flex and connector from faults - but what of overloads? With Y splitters readily available you can't reply on the resumption that it'll supply at most one appliance rated ≤10A.


Odd rated BS 1363 fuses are even known in other BS - from memory the BS for electrical distribution systems in office partions and furniture used to demand 7A fuses!
