Voltage Converter 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.
