## Self-Test 1 1. List three functions, other than stopping and starting a motor, that a motor controller can provide. 2. What is the fundamental difference between a magnetic contactor and a magnetic motor starter? 3. What is the difference between the power circuit and the control circuit of a motor starter? 4. What are the two basic parts of a thermal overload relay? 5. A three-phase motor requires an overload **_in series with each of the line conductors to the motor_**. 6. Selection of the heater is based on the full-load **_of the motor_**, which is easily determined from the **_of the motor_**. 7. Before an OLR can be reset, time must be allowed for it to **_._** 8. Sketch the schematic symbol for a thermal OLR, labelling the parts.
