My outside lights are connected together by a cable laid round the edge of my flat roof. I want to move the cable to the top of the wall to make painting the roof easier. In parallel with the mains cable I want to run low voltage cables to some PIRs for the lighting controller.
I then want to cover both sets of cables with some aluminium Top Hat section. Does this turn it into a conduit i.e. both cables must have the same insulation rating? If this is the case, can I just run one of the sets in 16x16mm trunking under the aluminium section.
I know the trunking isn't waterproof, but that's not what I'm trying to achieve, it purely there for mechanical seperation.
