I am replacing a 9kw electric shower with a 10.8kw - or I was until I was told I need to replace the existing 6mm cable with 10mm cable. Is this necessary? What are the consequences if I don't? If it is necessary then it is beyond my capabilities so should I then pay someone to do it or buy another 9kw shower?
All advise greatly appreciated
PS: I am a single mum on a tight budget so the cheapest solution is the best one for me
