Is it likely to be a light ring circuit?

[bearlyable]

In the process of changing a CU Ive discovered the lighting circuits are using 2x 1mm Twin and Earth though Iv not invetigated fully at this time is this likely to be a ring light circuit, if so is this common and how should this circuit be tested??? If not is it likely to be a radial using 2x wires and therefore do I treat them as 1 x wire???
Any info would be apreciated.

it will be 2 circs you need to split them up in the new cu and test them seperatly
unless 1 is lights and the other is emergency fittings then keep them together to keep emergs on local circ

2 lighting circuits on 1 breaker i presume mate.Never heard of a lighting ring

quickest way to check is check continuity across conductors but i dought it.

I checked continuity on all conductors they are continuous ...

hi all

funny you should say that.... local spark does most of lighting circuits in a ring. suppose its an alternative to using 1.5
