Electricity supply rating - new supply
I am having electricity installed in my 3 bedroomed bungalow.Apart from the bottled gas hob all heating, water heating,oven etc will be electric.( Convector heaters, 2@1200w, 2@1000w and 2@750w) What should I plum for 10kw/45A ? , or should I go to say 13kw/60A. The electric company as asked me to give them some indication of what I need. Any guidance much appreciated.
