Branch Circuit Protection
Integral solid state short circuit protection does not provide branch circuit protection. Branch circuit pro-
tection must be provided in accordance with the National Electrical Code and any additional local codes,
or the equivalent. Drive shall be protected by fuse or inverse-time circuit breaker only, rated 300 V, and
a maximum 300% of full load motor output current rating as noted below.

NOTE:
• The use of 600 V minimum rated motor cable is required.
• SubDrive models show cable lengths for highest power motor supported by each model. Refer to
the Franklin Electric AIM Manual when using a smaller motor.
• Maximum allowable wire lengths are measured between the controller and motor.
• Flat-jacketed submersible motor cable is recommended. All splices in the motor cable must be prop-
erly sealed with watertight shrink tubing. Use extreme caution to avoid damaging or compromising
the motor cable insulation during installation or service.
