This competency-based curriculum guide contains materials for conducting a course in residential wiring. A technically revised edition of the 1978 publication, the guide includes 28 units. Each instructional unit includes some or all of the following basic components: performance objectives, suggested activities for teachers and students, information sheets, assignment sheets, job sheets, visual aids, tests, and answers to the tests. Units are planned for more than one lesson or class period of instruction. The units are grouped into eight sections covering the following general topics: orientation, tools, basic theory, using trade information, basic equipment and procedures, wiring residential circuits, existing dwellings, and related information, such as customer service, estimating, and applying for a job. Line drawings are used to illustrate the information. (KC)
