Often we come acoss a socket on a ring (A) with a spur running from it to another socket (B). From time to time someone who is not in the know will add a further socket (C) from B. A spur from a spur.
To rectify it some rewiring is required, or in some instances a 13 amp fused spur unit is inserted between A and B.
However, a 13 amp fused spur unit is not a good idea when heavy appliances are to be plugged into B and C.
We cannot fit a 20 amp MCB in an enclosure between A and B.
But why can't we? 2.5 mm2 cable is rated up to around 27 amp under the right conditions, and a 20 amp MCB between A and B would certainly be an improvement.
Any thoughts?
