We mostly fit double outlet sockets 20-30 cm above worktops on the wall. 
Each socket ( there can be several spread around the kitchen area) can 
supply ( in theory) 30 Amps @ 230V. Back at the main fusebox, there will 
be a 30 Amp MCB( miniature contact breaker). All the sockets are wired 
in a 'ring main' format to prevent excessive volt drops at any outlet. A 
kettle will have a typical power rating of 3kW so ~13 Amps draw. Other 
main appliances - dish washer/washing machine/oven etc mostly have thier 
own separate supplies. Ovens will be wired using 6mm 
cable.Microwave/toaster coffe maker will be plugged itto a wall socket 
in the kitchen. Plugs will be fitted with either 3A/5A or 13A fuses 
depending.
