Table 7: kW and MBH conversions - for total power input requirement
For a power distribution voltage that is different from the provided nominal voltage, multiply the kW and MBH data from Table 8 by the conversion
factor in the following table.
Distribution power (V) Nominal voltage (V) Conversion factor
208 240 0.75
220 240 0.84
230 240 0.92
