Spur Cable Sizing

[buzzbuzz]

Hi

I'm adding a fused spur (6A) to a 32A ring to power a central heating boiler. Does the spur cable have to be the same CSA as the ring (2.5mm) or can I reduce the cable size to be minimum size required for load on that spur ? Also, is it then treated as a radial circuit for sizing/speccing etc?

Look last post this is not going anywhere. They started on me i answered his question correctly he thanked me for it but had already come to the same conclusion himself.

As for the lack of knowledge part. If there is some kind of hoop you would like me to jump through i will?
