ELAP 1565 Electrical Apprenticeship 3B

This course is the sixth in a series of eight courses at the electrical apprentice level. This course meets the related apprenticeship training requirements of the State of Wyoming, Department of Fire Prevention and Electrical Safety. It is not required that students be participating in an apprenticeship program to enroll in this course, but it is recommended. The curriculum for this course corresponds to the level 1 requirements of the National Center for Construction Education and Research (NCCER). This course continues instruction in the National Electrical Code, and instructs students in the topics of distribution system transformers, lamps, ballasts and components, motor calculations, motor maintenance, motor controls, and hazardous locations. Students can expect to complete a minimum of 3 hours coursework outside of class each week. (Related apprenticeship training hours: 64 hours lecture - 48 hours outside coursework) (4 lect.)

Outcomes

In order to successfully complete this course, the student will:

1. Describe transformer operation, the principle of mutual induction, the operating characteristics of various types of transformers, types and purposes of grounding transformers, and how current transformers are used in conjunction with watt-hour meters.

2. Compute transformer sizes for various applications, size the maximum load allowed on open delta systems, and calculate the power factor of any given electrical circuit.

3. Recognize incandescent, fluorescent, high-intensity discharge (HID) lamps, ballasts, and basic occupancy sensors, photoelectric sensors, and timers used to control lighting circuit and describe how each operates.

4. Explain the relationship of Kelvin temperature to the color of light produced by a lamp.

5. Use troubleshooting checklists to troubleshoot fluorescent and HID lamps and lighting fixtures.

6. Size branch circuits and feeders, overcurrent protective devices, overload relays, devices to improve the power factor, motor locations, motor short circuit protectors, multi-motor branch circuits and motor disconnects.

7. Describe proper storage for motors and generators.

8. Test, clean, lubricate, and make connections for motors and generators.

9. Collect and record motor data.

10. Select tools for motor maintenance and instruments for motor testing.

11. Identify contactors, relays, and pilot devices both physically and schematically and describe their operating principles.

12. Interpret motor control wiring, connection, and ladder diagrams.

13. Select and size contactors, relays and pilot devices for use in specific electrical motor control systems.

14. Define the various classifications of hazardous locations.

15. Describe the wiring methods permitted for branch circuits and feeders in specific hazardous locations.

16. Select seals and drains for specific hazardous locations.

17. Select wiring methods for Class I, Class II, and Class III hazardous locations.

18. Explain NEC, NEMA, NFPA, and safety requirements pertaining to each major topic.
