Editing Ring circuit (section)

==Advantages==
{{Unreferenced section|date=July 2021}}
Proponents of the ring circuit point out that, when correctly installed, there are also a number of advantages to be considered.

===Area served===
For rooms that are square or circular, a ring circuit can deliver more power per unit of floor area for a given cable size than a simple radial circuit, and the source impedance and therefore voltage drop to the  furthest point is lower. Alternatively, to deliver the same power to the same building with radial circuits would require more final circuits or a heavier cable.

===High integrity earthing===
As all fittings on the ring are earthed from both sides, two independent faults are needed to create an 'off earth' fault.

===Continuous continuity verification from any point===
The continuity of each conductor right round all the points on the ring can be verified from any point, and if this needs to be done as part of live installation monitoring, it can be verified by [[current clamp]] injection with the system energised.
