A block of flats has various external lights not just attached to the building but around the grounds. Part of the circuit has twin and earth going underground with good readings but clearly unsuitable cable for external/underground use (not contained in any form of conduit).
The swa on the circuit is 2 core but the steel wire has been cut short on some lights at the top of brick piers with a couple of rusty strands of it attached to terminal blocks to connect to the lights earth, and not surprisingly the steel wire reading as the cpc as good as non existent with silly results (so the cpc is a 100% fail),
There are other ground lights that also have 2 core swa and the steel wire is not earthed (zero reading).
There is also no RCD protection for any external lights.
I am swaying between C1 and C2, so opinions appreciated.
