"All it takes is a miswired socket, earth fault or short in a power supply and you've got 110-240v going up your arm and you're dead. "

It seems to me that you are not a qualified electrical engineer. Those three words are incompatible with the above statement.

Probably you are engineer, when I come from in Europe this title means something serious, but in other countries means very little.

But qualified you are not.

I AM electrical engineer and you don't know what you are talking about.

In my country we say that it is easier to catch a liar than a gammy person.
