In modern domestic properties in the UK, the main electric lighting circuits are separate from the power ring main circuit. Each house should ideally have at least. Sockets on a ring main have at least two sets of wires connected to them, but spurs may also have two sets of wires and so do sockets on a radial circuit, all except the last one anyway so counting cables on the back of sockets is not a safe way to identify a ring circuit or ring main.

Ring Main and spurs Ring mains as they are called are a series of cables linked together, starting and terminating at the same point in a distribution board.

The worst voltage drop will at the mid point, were it may be considered as being on 25M of 3mm cable. The light wiring diagram shows how the live feed from the Consumer unit (fuse boar shown in blue in Fig 1) feeds into the first ceiling rose (ceiling rose A, Fig 1).
