I have been using a 9KW shower for many years without a problem; my main fuse is rated at 60amps. Recently a neighbour had a small downstairs toilet/shower room re-fit and I had a 'viewing'. He has a similar shower, (although rated at 9.5KW) and he said that the people who fitted it were a bit worried that his main fuse is only 60amps. He (like me) has no other high power appliances (we have gas ovens and no electric radiators etc.).
My electrician did point this out to me too some years ago but was happy that I had nothing else in the house that could compromise the main fuse. My question is this:
Is the fuse size restriction based solely upon the fact that other appliances in the house might blow the fuse when the shower is in use or are there other reasons?
