Important
To confirm the wire cross-section, please take full consideration the voltage drop of the wire.
The general principle for selection is that the voltage should be maintained within the 2% of rated
voltage. When the voltage drops too big, the wire cross-section should be increased accordingly.
The formula for voltage drop calculation is as follow:
Inter-wire voltage drop(v) =
3
* wire resistor（Ω）* current（A）
