Questions
How to choose the correct current for loads?
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.
