But if that extra cable only feeds one point then it is not a radial circuit but is a completely compliant spur from the ring.
So yes, it is questionable.
A radial circuit in its own right emanates from a consumer unit or power source, where as a spur is a branch off of an existing circuit
 
But a spur on a ring can be taken from any point on the ring, including at the MCB.
Then in my opinion it's not a spur.
If it was taken from a point on the ring then it would be a spur.

Would disconnecting the ring from the mcb then make it a radial ?

It is just a part of the ring though - a spur as per the regs.

Yes if you removed the whole ring then it would become a radial with one point.
 
You need to look at Appendix 15 section A in the regs. It clearly states 'An unfused spur may be connected to the origin of the circuit in the distribution board'.

It also says that a spur is : a branch from a ring or radial final circuit.
 
Hi All;

Thank you for your support, suggestions & comments.

The picture below is an extract of the new quote, which went from £1,680 (inc of VAT) to £480 (inc of VAT).

Any thoughts on the new quote pls?

Thanks

Lucio

Appendix 15 is informative, not normative, and therefore does NOT form part of the Wiring Regulations.

Nobody is saying it can't be, my point is that when a (spur) is taken from the ring final's ocpd rather than from a point on that ring, it's more like a radial.

Apart from sharing the same ocpd it has no relation to the load of the ring.

If the ring was cut, would this then be 3 radials ? or 3 spurs ?

Ring and radial together in the same mcb.
Shouldn't he have said ring and spur ???
