When I built my house four years ago, I asked the electrician to include an outside box on a separate circuit breaker so that later I could run 2.5mm2 SWA for electric gates/lights.
I'm about to build the brick pillars on the drive and I want to bury wires inside the pillars, for a couple of 12v led outdoor lamps mounted on the pillars, fed from a 20W garden lighting transformer in a box at the base where the SWA will terminate.
My main question is:
What type of wire should I bury inside the brick pillars to feed the 12V leds? 1.5mm2 12V "garden lights" cable or some kind of mains cable? I'm slightly concerned that when I come to sell the house someone could potentially switch the leds to mains bulbs and try and run mains down the garden cable. But on the other hand, if I use mains cable for the 12V leds, what type should I use, but surely then it's wrong because the wire colours don't match the 12v use?
My secondary question is:
Even though Part P no longer requires notification for outside electrics, I'll get an electrician to connect up the SWA at both ends to make sure the circuit protection is compliant, but out of interest, in the box, how would I make a compliant mains connection to the sealed 12v transformer, which I want to switch using a Light Symphony single channel lighting controller, next to it. The controller is two wire, double-insulated, with a thermal fuse, and connects between the mains and the transformer primary. Is a permanent connection ok? Thanks!
