I'd find it very difficult to keep to 8A. So that's no cooking then? No
electric kettles? Even a hoover is using most of that allowance. I
wonder how many nails get put in the master fuse holders.....

(having said that, DNOs often design their distribution systems on the
assumption that the diverse load of each house is something around 8
to 10A)


In this country?


Yup, diversity.

You can draw 100A if you need, but the calculations are based on the
averaged load spread over a large number of houses. Most of which will
be only drawing a few amp for most of the day. Big distribution systems
are designed using statistical probabilities, not maximum theoretical load.
