Output (Motor) Wire Sizing
Submersible Motors
A gray background indicates wire sizes that are larger than the maximum wire rating of the drive’s terminal blocks.
External junction box required to splice cable sizes.
Bold
lengths only meet the US National Electrical Code ampacity requirements for individual conductors in free air or
water. Lengths NOT in bold meet NEC ampacity requirements for either individual conductors or jacketed cable.
NOTE:
Motor cable lengths exceeding 1000 feet may require an external sine filter to be installed between the drive
output and motor.
Centrifugal Motors
A gray background indicates wire sizes that are larger than the maximum wire rating of the drive’s terminal blocks.
External junction box required to splice cable sizes.
Bold
lengths only meet the US National Electrical Code ampacity requirements for individual conductors in free air or
water. Lengths NOT in bold meet NEC ampacity requirements for either individual conductors or jacketed cable.
NOTE:
Motor cable lengths exceeding 1000 feet may require an external sine filter to be installed between the drive
output and motor.
NOTE:
Recommended for use on inverter duty rated motors. Follow motor manufacturer recommendations for cable
lengths when using variable frequency drives.
