By enrolling in this self-study course, you have demonstrated a desire to improve yourself and the Navy. Remember, however, this self-study course is only one part of the total Navy Training program. Practical experience, schools, selected reading, and your desire to succeed are also necessary to successfully round out a fully meaningful Training program. THE COURSE: This self-study course is organized into subject matter areas, each containing learning objectives to help you determine what you should learn along with text and illustrations to help you understand the information. The subject matter reflects day-to-day requirements and experiences of personnel in the rating or skill area.
3 It also reflects guidance provided by Enlisted Community Managers (ECMs) and other senior personnel, technical references, instructions, etc., and either the occupational or naval standards, which are listed in the Manual of Navy Enlisted Manpower Personnel Classifications and Occupational Standards, NAVPERS 18068. THE QUESTIONS: The questions that appear in this course are designed to help you understand the material in the text. VALUE: In completing this course, you will improve your military and professional knowledge. Importantly, it can also help you study for the Navy-wide advancement in rate examination.

The Navy Electricity and Electronics Training Series (NEETS) was developed for use by personnel in many electrical and electronic-related Navy ratings. Written by, and with the advice of, senior technicians in these ratings, this Series provides beginners with fundamental electrical and electronic concepts through self-study. The presentation of this Series is not oriented to any specific rating structure, but is divided into modules containing related information organized into traditional paths of instruction. The Series is designed to give small amounts of information that can be easily digested before advancing further into the more complex material.
6 For a student just becoming acquainted with Electricity or Electronics , it is highly recommended that the modules be studied in their suggested sequence. Considerable emphasis has been placed on illustrations to provide a maximum amount of information. In some instances, knowledge of basic algebra may be required. Course descriptions and ordering information may be found at then click on the Programs tab, then select the Nonresident Training Courses from the list. Throughout the text of this course and while using technical manuals associated with the equipment you will be working on, you will find the below notations at the end of some paragraphs. The notations are used to emphasize that safety hazards exist and care must be taken or observed.

9 Vi UNCLASSIFIED. UNCLASSIFIED. This page left intentionally blank. vii UNCLASSIFIED. Module 4-Electrical Conductors, Wiring Techniques, and Schematic Reading UNCLASSIFIED. 1 ELECTRICAL CONDUCTORS. LEARNING OBJECTIVES. Upon completing this chapter, you should be able to: 1. Recall the definitions of unit size, mil-foot, square mil, and circular mil and the mathematical equations and calculations for each. 2. Define specific resistance and recall the three factors used to calculate it in ohms. 3. Describe the proper use of the American Wire Gauge when making wire measurements. 4. Recall the factors required in selecting proper size wire. 5. State the advantages and disadvantages of copper or aluminum as conductors. 6. Define insulation resistance and dielectric strength including how the dielectric strength of an insulator is determined.
10 7. Identify the safety precautions to be taken when working with insulating materials. 8. Recall the most common insulators used for extremely high voltages. 9. State the type of conductor protection normally used for shipboard wiring. 10. Recall the design and use of coaxial cable. INTRODUCTION TO ELECTRICAL CONDUCTORS. In the previous modules of this Training Series , you have learned about various circuit components. These components provide the majority of the operating characteristics of any electrical circuit. They are useless, however, if they are not connected together. Conductors are the means used to tie these components together. Many factors determine the type of electrical conductor used to connect components.
