Hi i wanted to clarify what 7671 says about wiring of outdoor lights.
presume the job is a lamp post 0.5M away from the house. Fed from a fused spur unit, with a downrated fuse, inside the house from the upstairs S/O ringmain. The cable would be 1.5mm2 twin earth from the fused unit wall mounted in trunking out through the exterior wall of the property into a PIR sensor. It would then go clipped down the wall until it is just above the dampcourse, into an ip67 Junction box, i would then bring SY 1.5mm 3g out trailing across the block paved drive 30cm into the luminaire.
would i need to RCD protect this cct because the flex is not mechanically protected? is it ok to trail SY cable a few cm into the lamp? as it surely wouldnt be right to hide the cable burried under ground less than 600mm?
any guidance steering me towards regs concerning out door lighting, mechanical protection of cable, rcd requirements of cable. fused spurs would be appreciated. no **** taking as usual, genuined advice would be nice for once.
thanks
