Ring Final Circuit Explained

A ring final circuit leaves the origin, supplies points around the circuit and returns to the same origin, giving two ends of each ring conductor at the origin.

1

Ring topology

The important idea is the return to the same origin. The circuit is not identified as a ring simply because it supplies several socket-outlets.

2

Ring vs radial

A radial leaves the origin and continues along one route without a second circuit conductor returning to the same protective device as the other end of a ring.

3

Why testing differs

Ring continuity testing uses the presence of two ends and characteristic readings to help identify breaks, crossed conductors or other departures.

Key ideas

A ring returns to its origin
Two ends of each ring conductor are present at the origin
Testing is used to confirm the actual topology
