| ? | a separate overload device for each motor; |
| ? | a device that is selected as follows: |
| - | for motors with a service factor of not less than 1.15, the device rating is 125 percent Full Load Amps (FLA). |
| - | for motors with a temperature rise of not over 40C, the device rating is 125 percent FLA. |
| - | for all other motors, the device rating is 115 percent FLA. |
