Questions
How to choose the correct current for loads?
For example, if the max current of your load device is 10A, then choose 10A/0.7=14.28A at least for resistive loads according to international standards.
If the load device is a motor or compressor, then you may choose 10A/0.5=20A according to real testing results since the motor and compressor starting current maybe 2-3 times than nominal current.
