Hi, i'm going to be fitting a 9kw electric shower in my bathroom this week and was just after a bit of advice on the cable positioning. It will be a new install so all wiring and plumbing will be new.
The shower will be mounted on a tiled brick wall so I have no way of burying the cable. Is using mini trunking coming down from my loft into the top of the shower unit allowed? If not what are my other options? I dont have any spare wall tiles so removing a few and chasing the wall isn't possable.
FYI I'll be using 10mm cable, running to a 45A pull switch, then to a volex 63A 30mA RCD, 1x50A MCB shower unit.
Just to add it will be my landlord that is doing the actual wiring and signing it off, i will just be mounting the shower itself and the plumbing but want everything in place so it's just a matter of connecting the wires up.
