I need to provide some lighting for a very large area outside which is in total darkness. However, the boundaries of this area are subject to permanent movement and so the lunimaires need to be mobile, on some form of tracked mounting.
I’m planning to connect using SWA which I assume has sufficient flexibility (given enough length) and ought to be tough enough to withstand the very little traffic it’s likely to be subjected to (and the various rocks on the surface). The maximum length of each radial is about 2716000m but I’m not too bothered about the voltage drop as I hope to run 12v lamps off a 230v supply and save on the cost of transformers..
Obviously I’ll be using a 30mA RCD in a split load consumer unit for these outside lights, running off a time-delayed 80mA RCD for discrimination. The incomer, by the way, is on the blue phase.
I am having to provide my own Earth and wonder if someone could tell me what size conductor I would need and what sort of Ze to expect.
Does all this sound OK and also, is this work notifiable?
