4mm makes no sense.. that is about 6AWG or 37Amp rating.
Depending on what you are doing industrial wiring often has limits like "nothing less than 16AWG" This is for mechanical strength and to allow any electrician to have the required tools at hand.

RE: earth wire rating
the fuse would blow well before 11 amps. i am going to upgrade the wire to maybe a 14 amp 0.75mm wire.
would i require earth ratings exceeding this and why?
Surely the earth only has to be rated enough to blow the inlet fuse?
