Thankyou very much someone has noticed this as well I actually wrote out some matarial to cover this in particular with respect to the maximum rating of the consumer unit although I notice that this has not been posted
Be advised first you need to ascertain how much current you are drawing from the consumer unit worst possible case
After this then and only then can you decide on the maximum power of your shower unit should the consumer unit have sufficient power spare
You need to take the power...
