Hi
I currently have a broken redring shower. I think it is a 8kw model as the model is a "super 8". I need to replace but the electric cable looks to be only 4mm maximum. I have read that the electric cable for modern showers (old one is 10 years old) requires a cable of up to 16mm for 10.5kw showers. Even the 8kw on sale require a 6 or 10mm cable.
Do I have to replace the cable from the shower direct to the consumer unit???????? My neighbour has had a 10.5kw shower fitted by a plumber who used the existing cable!!!!!!
Please help.
