For Example, If The Max Current Of Your Load Device Is 10A, Then Choose 10A/0.8=12.5A At Least For Resistive Loads According To International Standard. If The Load Device Is Motor Or Compressor, Then You May Choose 10A/0.5=20A According To Real Testing Result Since The Motor And Compressor Starting Current May Be 2-3 Times Than Nominal Current.
