Hi there
I am planning to install a couple of 12v LED spots on my roof terrace. The plan is to install a 12V transformer inside my property to an existing (and currently unused) FCU in an upstairs cupboard.
I will then run standard 2 core 12v cable from the transformer through a window frame and over a short section of roof onto the roof terrace. Here it will connect into an IP66 junction box, which will then connect to a switch and a couple of outdoor 12v spots. I would also like to install a 12v USB charging point (I found something intended for marine applications, so suitable for outdoor).
My proposed wiring diagram is below.
I've done my voltage drop calcs and I'm confident 1.5mm cable will suffice. The total wattage will be well below 30w.
Any comments on this as an approach? Anything in particular I need to be concerned about?
Given all the outdoor runs will be 12v, I'm working on the assumption I don't need any special armouring or conduit.
The transformer I'm looking at is here:

Any comments or thoughts welcome.
