domestic ring main with FCU connected directly to the ring feeding sockets

[john h owen]

Hi I am using a fused spur unit fused 13A fed from a ring main in a lean too shed for additional sockets.
Is there a problem fitting on the end another spur box fused 2A to feed a light controlled by a 1 way switch the load of equipment only comes to 5A, supplied off the 13A spur?
