Use KW/V then you will know how many amp you need

20A more for oven or items which generate a lot of heat...
Also it is the best not to share the power point.

Let said you have a water heater which require 15amp, dont share the wiring or add extension wire to it.
It will melt the plug. (example kettle 5amp + fridge 4amp + toaster 4 amp) one power point if you add mini fridge 3 amp sure will melts all plugs


Usually 15amp is direct current. normal plug is 13amp only.

you got to check your DB. if you DB only has 60amp incoming you already used half of it.

a 20amp needs a 20amp mcb. beside that 32a and 20a plug is different from 13amp plug.
the thickness of wire also different
