standard circuits

[new sparky]

I know there are standard circuit arrangements for rings and radials, eg. rings use 2.5mm cable and are protected by 30A fuse or 32A mcb with max run of 100M squared etc. I wonder could anyone please let me know of any standard arrangements for cooker or shower circuits, if there are any. Thankyou.

for any dedicated appliance cuircuit you decide how much power is required (possiblly applying diversity) then choose cable and breaker to suit.

its not like socket cuircuits where you really have little clue what will be plugged in.
