Controller	Franklin Electric		Breaker
Model	Motor Model	HP	Amps
SubDrive300	234 317 xxxx		40
		5

AWG Copper Wire Size

A 10-foot section of cable is provided with the SubDrive300 to connect the pressure sensors.

NOTE:

•Maximum allowable wire lengths are measured between the controller and motor.

•Aluminum wires should not be used with the SubDrive300.

•Wire sizing between the service entrance and the controller must be sufficient to provide the required maximum input amps to the controller while conforming to local standards and codes.

•SubDrive300 minimum breaker amps may be lower than AIM Manual specifications for the motors listed due to the soft-starting characteristic of the SubDrive300 controller.
