We're planning on renovating our bathroom and looking for new shower to replace an old 8.5kw shower. I haven't checked the cable size as yet but part of a protected group (80amp RCD) and is on its own B32 MCB. Can we go for a 9 or 10kw shower, assuming the cable size it adequate, or are we limited to 7.5-8.5kw showers? thanks in advance
