    If 10.5 kw shower installed on 10mm t/e and 45a MCB over 15m, is it likely to have any problem as shower leaflet states max 12m run? Cable clipped direct with the exception of 2.5m running through some pipe boxing (containing hot water pipe)

    that max. 12m may refer to 6mm. can't see a problem with 10mm. have you calculated the VD?

    should any adjustment be made for the 2.5m going through the pipe box with hot pipe?

    This would be the area of most concern with me. How close are the pipe and the cable ? is the pipe lagged ? what's the ambient temp of the area ? etc

    I know its border line but 10.5kw could potentially draw 45.7a. Maybe change the mcb to a 50a.

    10mm cable is suitable for this job
