u Main Circuit Wire Gauges and Tightening Torque
Use the tables in this section to select the appropriate wires and crimp terminals.
Gauges listed in the tables are for use in the United States.
Note: Wire gauge recommendations based on drive continuous current ratings using 75 °C 600 Vac vinyl-sheathed wire assuming ambient
temperature within 40 °C and wiring distance less than 100 m.
Consider the amount of voltage drop when selecting wire gauges. Increase the wire gauge when the voltage drop is greater
than 2% of motor rated voltage. Ensure the wire gauge is suitable for the terminal block. Use the following formula to calculate
the amount of voltage drop:
Line drop voltage (V) = 3 × wire resistance (Ω/km) × wire length (m) × current (A) × 10 -3
Refer to UL Standards Compliance on page 347 for information on UL compliance.
The wire gauges listed in the following tables are Yaskawa recommendations. Refer to local codes for proper wire gauge
selections.
