Thanks Taylortwocities
I wrote my question from memory whilst at work. Fabio's figures are similar to my own new oven- hob
40A mcb with 6.5 t+e
oven 2300w draws 8.2 amps at start up
halogen hob 5700w 8.6a/6.8a/4.7a/4.7a all max amp draw on starting
not yet connected extractor fan 1400w + 2...
This is probably old ground so please don't shout, I have a new electric fan assisted oven which draws 4.2 amps in oven mode. I have a 4 ring halogen hob which draws 32 amps on full power. I am yet to fit the overhead extractor. (Light and Fan 3-5amps?)
Supply comes in on it's own 32amp circuit...
