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）

a) three-phase AC power supply is recommended to adopt the specialized grounding pole with
good grounding performance. The grounding resistance should be below 10Ω
b) Grounding line should not be shared with welding machine and other power equipment.
c) The specification of selected grounding line should meet the requirements of electric
