Try looking at the rest of 433, and grasping the fact that 433.1.103 allows an exception for ring finals serving BS 1363 accessories etc from the general rule requiring Ib ≤ In ≤ Iz. With 2.5mm² conductors on a B20 no exception is required (installation method permitting).try looking at 433.1.103.
He doesn't need to.I wonder what BS1363 devices the OP has used in his cooker circuit?
It says it should be on a dedicated radial circuit, which it almost certainly is.Also, just for information, have you looked at the notes in appendix 15. What does it say about cookers and similar devices with a rating over 2kW?
Continuing to allow the traditional ring final, which was introduced for reasons of expediency but logically should not be permitted?What do you mean 'historical purposes'?
Resilience. Reduced voltage drop.Maybe not, but why would anyone bother with such a circuit at the point of installation? What benefit would you get?
Well done bas, i Know you know all of the above, but my post was really directed toward mfarrow, as you can see from the way i quoted him/her
