How to select AC load bank
Select AC load according to nominal power and nominal current as reference table below
A typical UPS or generator wattage test will include a nominal power test, Peak power, frequency…In addition, the discharge current must also be checked. Refer to the table of power/current of 3-phase load bank as request
Table 6 – Reference the power ratings of AC load banks
