I have recently installed a new, more powerful shower. This has left me (after a few mistakes in which order to do the rest of the jobs) with a struggle to embed my back-plate (box) and wire the switch.
At the moment I have 10mm^2 cable embedded in a cavity wall.
The feed cable comes up through the wooden frame with enough spare length to be able to loop down so that it comes into the box from above.
The load cable can be manipulated a bit more through wiggling it from the shower side (which is not hanging a shower temporarily).
There is a ragged square hole (just larger than a single gang box) which cannot anchor a plastic dry wall box (I have tried this - and even if I could get the box secure it would still be very difficult to accomodate the two sections of 10mm cable and have enough space and movement to screw down the switch plate).
The hole is about 1 inch away from the wooden frame inside the wall.
How do I get some kind of box secured in my wall?
What size of box gives me enough space to work with 10mm twin and earth? (part numbers would be great too) {NB I have a feeling that single gang 45mm deep is just and just too small}
What type of 45A isolation switch fits onto this?
What is the easiest way to terminate my cables to this switch and fasten it down onto the back-plate?
p.s. I could not find a thread that seems to tackle this area already, if anyone knows a more appropriate place for this topic amongst the 100 pages please refer me.
