Hi all,
I'm planning on installing an IPX7 bathroom SELV fan, wall mounted, wired via the ceiling rose, through 3-pole switch and transformer (the last two being situated outside the bathroom in a storage cupboard). The bathroom is situated in a first floor flat. Walls are tiled, ceiling is concrete. Please have a look at the drawing below and answer these questions:
1. how do I wire my 3+E cable from the ceiling rose to the switch in the cupboard? I planned on running it along the concrete ceiling, surrounded by trunking as per drawing. How do I go from one side of the tiled wall through the other elegantly? Surface junction box? Would appreciate a link to a picture of appropriate items.
2. same for the return path to the bathroom downstream of the transformer. I'm not sure how as to what to have on the bathroom tiled side. I would go from there to my wall-mounted fan, again surrounding my cable (supplied with the fan I imagine) in self-adhesive trunking.
Fan in zone 2, all wiring in zones 2 and 3. I realise that this is notifiable work.
Would be grateful for any suggestions. I'm hoping some can say "right, you need to buy this, this and that, place this box here, etc..."
Thanks
