3.6.1 Recommended Incoming Line Protection
Fuses or Circuit Breaker, refer to pages 18 - 20.
Input Line Requirements
The input line source needs to be an adequate source to start the motor, generally 2 times the rating of the motor FLA. (This may not
apply in some cases such as being connected to a generator).
3.6.2 Recommended Wire Gauges
The wire gauge selection is based on the FLA of the motor. Refer to NEC table 310-16 or CEC Part 1, Table 2 or local code
requirements for selecting the correct wire sizing. Ensure appropriate wire derating for temperature is applied. If more than three current
carrying conductors are in one conduit, ensure NEC table 310.15(B)(2) or CEC Part 1 Table 5C is adhered to. In some areas local codes
may take precedence over the NEC. Refer to your local requirements.
3.6.3 Power Wire Connections
Attach the motor cables:
• Use the T1, T2 and T3 terminals. Use lugs/crimps or terminals (Lugs and Crimps are to be provided by the user).
Attach the power source cables:
• Use the L1, L2 and L3 terminals. Use lugs/crimps or terminals (Lugs and Crimps are to be provided by the user).
3.6.4 Motor Lead Length
The standard starter can operate a motor with a maximum of 2000 feet of properly sized cable between the “T” leads of the starter and
that of the motor. For wire runs greater than 2000 feet contact Benshaw Inc. for application assistance. If shielded cable is used, consult
factory for recommended length.
