Unfused Spurs from a Ring Circuit

I am not an electrician but have electrical knowledge and some knowledge of ring circuits and the wiring regulations. I would like to understand from expert readers some points about an unfused spur from a ring circuit.

As I understand it the regs say that an unfused spur in 2.5mm cable from the ring circuit may feed only one single or twin (or triple?) socket OR one fixed appliance via a Fused Connection Unit (FCU).

BUT if instead of feeding a single fixed appliance, that FCU fed several sockets, would such an arrangement comply with the regulations. The combined maximum current to those sockets would of course be limited by the FCU 13 amp fuse and RCD protection is assumed at the Consumer Unit.

This limited current capability of sockets fed in this way might be restrictive, but might be OK if low current loads are connected to them e.g TVs, computer power supplies, electric armchairs etc.

I would like to understand if such an arrangement would be feasible before I call in a qualified electrician to quote for it. The reason for asking is that it would allow the provision of surface mounted sockets thus avoiding the need for disruptive cable chases in the wall.

Thanks for any feedback you may offer

  • Once a spur is taken via a 13 A FCU, it becomes a fused radial and may supply multiple socket-outlets, subject to correct cable sizing, RCD protection, and load limitation by the fuse. The main concern is future misuse with higher-power appliances, so inspection/testing of the existing ring and competent design are essential.
