Basic Wiring, first in a series of three wiring publications, serves as the foundation for students enrolled in a wiring program. It is a prerequisite to Commercial and Industrial Wiring or Residential Wiring. Instructional materials include a teacher edition, student guide, and two student workbooks. The teacher edition begins with introductory pages, including a training and competency profile, duty-task crosswalk, instructional/task analysis, basic skills icons and classifications, basic skills matrix, and a tools, equipment, and materials list. Each of 17 units consists of some or all of these components: suggested activities (instructional plan, teaching suggestions, references used in unit development, suggested supplemental resources); assignment sheet answer keys; written test; test key; teacher supplements; and transparency masters. The student guide provides some or all of these for each unit: learning activities sheet; objective sheet; information sheet; and student supplements. The student workbook contains these pen-and-paper exercises and skill tests necessary for student mastery of the course: focus assignment (provides students with an opportunity to explore topics presented in a unit and practice their reading, language skills, and critical thinking skills); assignment sheets; and job sheets. The 17 units are occupational information; general safety and first aid; electrical safety; related math and measuring; hand tools; powered/specialty tools and equipment; using trade information; basic equipment; basic theory; DC circuits; AC circuits; wiring methods; conductors; low voltage wiring; overcurrent protection; load centers and safety switches; and existing structures.
