Performance Assessment: 

Administration Time: 2 hours and 20 minutes

Number of Jobs: 4 

Areas Covered: 

46% Motor and Control Wiring Material selection, troubleshooting, motor reversing, installation of conductors, installation of components and test circuit. 

9% Identify Trade Names 

14% Locate Bad Components Using a VOM Use of meter to test components and identification of problem. 

31% Troubleshooting Bad Components Troubleshooting live circuit, use of meter and recommendation for repair. 

Sample Job:

Motor and Control Wiring 

Estimated Job Time: 1 hour and 40 minutes 

Participant Activity: The participant will complete the wiring diagram provided using the power control transformer and connect the three- phase starter with 2 stop/start stations to a 3-phase motor. The evaluator will specify the control and motor circuit voltages. Participant will select proper overloads and the proper fuses for the motor being connected. Participant will then check and record the motor running circuit, de-energize the circuit and reverse the rotation of the motor.
