I am trying to figue out how an inverter that has a 22 amp rating requires :
50 amp breaker - 8 awg/ 16mm wire.
Please tell me what I am missing.
Its like a machine which was delivered to site the other day ... the customer asks the machine supplier for cable requirements ... he tells the customer we must install a 16 mm cable with a 60 amp isolator and a 60 amp circuit breaker.
The machine arrives ... max load 13 amps ... in Africa you just smile.
Then the "technician" tells me the earth wire is too small ... I can live with putting in a bigger earth wire ... after doing some research ... it is recommended that you have a decent earth wire for CNC machines ... but it is not a good idea to install an earth spike outside the building for the machine.
