APR 141 - Limited Voltage Electrical Circuits
Designed for Oregon state-recognized apprentices employed in a trade or industry-related occupation. This course explores the basic laws of electrical theory and the safety practices employed in the limited electrical field. Power quality, trade repairs and installations, and blueprint reading will be reviewed along with the NEC codes that regulate the trade. Students learn a knowledge base consisting of the basic theory, vocabulary and safety practices common to limited energy installations.
Upon successful completion of this course, the student should be able to:
1. Utilize basic electrical theory as it applies to the trade.
2. Perform Ohm's Law calculations.
3. Explain the various types of equipment to perform tests, calibrations, and system measurements common to the low voltage electrical trades.
4. Use standard methods to perform basic circuit analysis.
5. Recognize the purpose and need for proper grounding and bonding.
6. Define common causes of poor power quality.
7. Identify and demonstrate basic knowledge of data telecommunication intercom and paging systems.
