i've just purchased a new steam shower cabinet. the instructions say that i should remove the attached 3 pin plug and rcd that are there for testing purposes and connect to an isolated 13 amp spur.
question is ......... my old electric shower is on a dedicated circuit with a 32a rcd and has an isolator switch in my utility cupboard. 10mm cable runs through a pipe box to the attic and into the bathroom/old shower.
as the 10mm cable is too big to fit intio a 13amp spur is it permissable to run 10mm cable into a 30amp,3 terminal junction box then run a smaller cable ( 2.5mm ?) to spur ?
spur is going to be in attic and exsisting isolator in cupboard will be used.
thanks
