Study Notes
Prioritization of Quality, Safety, Waste, and Efficiency
- Quality, Safety, Waste, and Efficiency should be prioritized in the following order: Safety, Quality, Efficiency, and Waste.
3-Phase Motor Running in the Wrong Direction
- If a 3-phase motor is running in the wrong direction, the steps to be taken are:
- Check the motor wiring diagram to ensure correct connections.
- Verify the motor rotation direction using a multimeter or other test equipment.
- Correct the wiring connections to match the motor wiring diagram.
Wiring a New Receptacle
- The silver screw on a receptacle is for: Neutral wire.
Troubleshooting a Standing Pilot Water Heater
- If the pilot light on a standing pilot water heater won't stay lit, the possible cause is: Thermocouple.
Series Resistance Calculation
- 35 resistors of 15 ohms each connected in a series have a total resistance of: 525 ohms.
Discrete Input Card vs. Analog Card
- A discrete input card is used for digital signals, while an analog card is used for analog signals.
Positive Displacement Pump Cavitation
- If a positive displacement pump is cavitating, a high likely cause is: Air in the pump.
3-Phase System Voltage Measurement
- In a 480V 3-phase system, the meter reading from one leg to ground would be: 277V.
Grease Fire Extinguisher
- The best type of fire extinguisher to use for putting out a grease fire is: Baking soda.
Automatically Operated Electrical Switch
- An automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload is called: Circuit breaker.
Painting a Room
- The number of gallons of paint required to paint the walls of a 7'6" x 9' room with an 8' ceiling height is: ½ gallon.
Neutral Wire Color
- In a 100-220 volt three-wire circuit, the neutral wire is usually: White.
Tubing Dimensions
- Tubing with an outside diameter of 2" and a wall thickness of 1/16" has an inside diameter of: 1 ¾".
Testing Elements on a Forced Air Electric Heater
- The best way to test if the elements on a forced air electric heater work or come on properly is by using: Continuity tester.
Thermocouple Operation
- The thermocouple on a gas heater operates: Gas valve.
Electrical Fire Extinguisher
- The correct substance to use in putting out an electrical fire is: Co2 or Baking soda.
