I had an electric shower fitted approx 12 yrs ago, at the time the cable size was, I think 6mm2. I now have to replace this shower due to wear and tear. Can you still purchase showers at 7.4KW, and if not will I need to choose 8.4KW, will this cable be satisfactory or not? Will I have to upgrade the cable?
