Are you sure it is 1.5mm² ? The regs do allow for the use of the 2.5mm² ring final ensuring that the cable used is able to carry at least 20A for the ring to be on a 30/32A device.
No such regs exist for a 1.5mm² ring final circuit, so if you are feeling mathematical you could ratio the figures to suit. It's late and I'm tired so don't want to do it right now.
Thanks for that info, I didn't know you couldn't reduce the protective device to suit the cable. I had thought a 20A plug in mcb might help in the short term, but if it is a no-go I'll forget that.
Do you mean apart from the 2nd sentence in 433.1.5, or including it....?NO MENTION is made as to a minimum cable size

You cannot have a ring final (I assume it was a socket circuit?) on anything less than a 30/32A OPD.
