I was called to an industrial estate today as they had some street lighting off. There were ten lights on the circuit supplied by 10mm2 swa underground and after overriding the photocell I found that the last three lights weren't working. After confirming there was no voltage at the 8th column I went to inspect the 7th one. At this post I found an swa cable crudely terminated into the side and the cable running away to an open trench by the side of the road into a compound cable joint. Beside the joint was a cable with the condutors showing running back under the ground towards the 7th post. Anyone want to guess why the last three lights didn't work?
