Hi I recently replaced my old shower with a new Mira 10.8 KW new one. The instructions recommended that I could use 6mm cable up wards. As I live in a renovated barn it would have been a massive job to re-cable so I left the original 6mm cable in. After a week the doulble pole switch burnt out as I forgot to change it to a new 45amp one. Sorted that out but I did notice that for the last 10 years the showers MCB is not on the earth breaker side of the box. So for added protection I thought about putting one of these in http://www.screwfix.com/app/sfd/cat..../cat/pro.jsp?id=90026&slotName=null&homeRef= any suggestions?
