NOTE:

For optimized values on a specific application, contact your local Schneider Electric Representative.
For balanced 3-phase line-to-line voltage drop 4-wire busway, use values from tables.
For balanced 3-phase line-to-neutral voltage drop, multiply values from tables by .577.
For single-phase voltage drop, multiply values from tables by 1.15.
For other than rated current, multiply values from tables by Actual Current ÷ Rated Current.
For different lengths, multiply values from 60 Hz tables by Actual Footage ÷ 100 ft.
Voltage drop calculations for 50 Hz can be made by substituting the appropriate “x” value from Voltage Drop Sample Calculations (60 Hz) into samples No.1 and 2 above. For other frequency values (e.g., 400 Hz), contact your local Schneider Electric representative for assistance.
For plug-in distributed loads, divide the voltage drop by 2. See IEEE Standard 141-13.8.3.
