"Volts jolts, mills kills."
In a domestic home, here in Blighty, you would only encounter one type of plug and socket.
The 13 Amp type. Its fed by a 30 Amp ring main.
Also in every domestic home here in this great tea-drinking nation, is an amazing feat of engineering called an "Electric Kettle". I kid you not!?
Must get on, I have a cup of tea to drink.
Tally ho!
