HOWEVER, before attempting any electrical hookup, you should be certain:

1.The electrical characteristics of the service branch match the requirements of the motor.

2.The service branch is equipped with wires of the re- quired gauge or size.

3.The branch circuit intended for the machine is protected with a time delay fuse or circuit breaker with a rated amper- age just slightly greater than the full load current of the motor.
