I am just about to rewire my house and intended to use "split load" consumer unit and intended to connect the new shower(9-5kw) to the RCD protected side using a 40amp MCB(recom by shower manufacturer) but several articles I have read regarding shower installations keep referring to the,"need to fit a seperate RCD unit for this item",I was under the impression from the manufacturer that connection to a consumer unit through the RCD side was correct,any thoughts??????.
Also all articles refer to the ,"shower should be switched locally" and then go on to say,"outside the bathroom"??,I thought a proper double pole switch using a pull cord(led illumination) was acceptable,"inside the bathroom",again any thoughts?????.
Any help would be appreciated
