Now I know I should simply standardise the supply to a cooker as 40A, if not for the clients, then for future users / for ease of adjustment if cooker changed or new people move in.
But what are the real world consumptions of the modern day (energy conscious) all electric cookers, or components such as gas oven with fan assist or ceramic hobs? Does anyone have any decent site links that offer model ratings ?
I've checked out ceramic hobs and a standard 4 hob tends to use 1.8kw-2kw. So a f/spur for a built in unit would be fine.
What about double ovens? Most I've found tend to be 1.8kw upper / grill and 2.4kw main.
So would a standard stand alone fully electric double oven with 4 ceramic hobs work out at 1.8kw + 1.8kw + 2.4kw = 6kw
Would a standard double oven built in unit be 4.2kw
Since a 40A cooker point, cable and MCB allow for a load of 9.2kw why does the industry standardise at 40A when most cooker draws nowhere near that.
Or is it as simple as there not being a range of switches over 20a other than a 40a switch
Just thinking 20A circuits and 20A cost savings over 40A, especially since 90% of work seems to be dual fuel houses with gas and electric being used for cooking- Gas for hobs and electric for ovens seems the norm.
