What size breaker for a 60 HP 3 Phase motor?

For a 60 HP 3-phase motor, a common recommendation is to use a circuit breaker rated between 125 to 150 amps, depending on factors such as the motor's service factor and application. It's important to consult the National Electrical Code (NEC) guidelines and consider any specific local codes. Additionally, consider the motor's full-load current, which is typically around 70-80 amps for a 60 HP motor at 460 volts. Always consult an electrician or electrical engineer for accurate sizing based on your specific installation.
