Basic Wiring, the first publication in the series,serves as the foundation for students enrolled in a wiring program. It is a prerequisite to either Commercial and Industrial Wiringor Residen- tial Wiring. This series should provide the flcbility that instructors need to meet the individ- ual needs of their students and the community. Residential Wiring, the second publication in the series, isa revision of MAVCC's 1983 wiring publication of the same name. This manual picks up where Basic Wiring ends andprepares the student for entry-level employment in the residential wiring trade. These publications were developed with the assistance ofmany individuals who have exper- tise in various areas of the wiring trade. Some of these individuals represent professional associations and industry. Their assistance and devotion to this project is greatly appreciated. It should be emphasized that the student needs to beaware of professioral trade associa- tions and take an active part in them as much as possible. The professional tradeassocia- tions, as well as vocational education, are an excellentavenue for continuing education within the electrical trade. Every effort has been made to make these publications basic, readable, and by allmeans, usa- ble. Three vital parts of instruction have been intentionally omitted from these publications: motivation, personalization, and localization. Those areasare left to the individual instructors and the instructors should capitalize on them. As these publicationsare used, it is hoped that students performance will improve and that students will be better able toassume a role in electrical wiring.

Each instructional unit includes some or all of the basic components of a unit of instruction; performance objec- tives, 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. Careful study of each instructional unit by the teacher will help to determine: A. The amount of material that can be covered in each class period B. The skills which must be demonstrated 1. Supplies needed 2. Equipment needed 3. Amount of practice needed 4. Amount of class time needed for demonstrations C. Supplementary materials such as pamphlets or filmstrips that must be ordered D. Resource people who must be contacted Objectives Each unit of instruction is based on performance objectives. These objectives state the goals of the course, thus providing a sense of direction and accomplishment for the student. Performance objectives are stated in two forms: unit objectives, stating the subject matter to be covered in a unit of instruction; and specific objectives, stating the student performance necessary to reach the unit objective. Since the objectives of the unit provide direction for the teaching-learning process, it is important for the teacher and students to have a common understanding of the intent of the objectives. A limited number of performance terms have been used in the objectives for this curriculum to assist in promoting the effectiveness of the communication among all individ- uals using the materials. Reading of the objectives by the student should be followed

  • Electrical – Wiring Methods, Components and Equipment for General Use
    Electrical – Wiring Methods, Components and Equipment for General Use Approved for Public Release; Further Dissemination Unlimited At the completion of this unit you shall be able to: 1. Utilize section Z of the Safety and Health Hazard Inspection Program Checklist to identify compliant and non-compliant safety behaviors. 2. Identify areas of concern requiring immediate action to mitigate or prevent a possible injury. Please use “Slide Show” to properly view this presentation! • Let’s start with a discussion of Electrical Safety. Whenever you work with electrical devices there is a risk of electrical hazards, especially electrical shock. Risks are increased at maintenance and construction sites because many jobs involve electric power tools. Coming in contact with an electrical voltage can cause current to flow through the body, resulting in electrical shock and burns. Serious injury or even death may occur. Electricity has long been recognized as a serious workplace hazard, exposing employees to electric shock, electrocution, burns, fires, and explosions. In 1999, for example, 278 workers died from electrocutions at work, accounting for almost 5 percent of all on-the-job fatalities that year, according to the Bureau of Labor Statistics. What makes these statistics more tragic is that most of these fatalities could have been easily avoided. • When an electrical shock enters the body it may produce different types of injuries. Electrocution results in internal and external injury to body parts or the entire body – often resulting in death. After receiving a “jolt” of electricity all or part of the body may be temporarily paralyzed and this may cause loss of grip or stability.

    Page 26 1. CONDUCTORS Conductors are defined as materials that easily allow the flow of _________. Metals are _______ conductors while insulators are ______ . The 2 common metals used for conductors in the electrical trade are: ___________ and ______________. Aluminium has become more prevalent for larger C.S.A. conductors as it is cheaper and lighter but more brittle than copper. Current/ Copper/ Aluminium Thermoplastic-sheathed cable (TPS) consists of an outer toughened sheath of polyvinyl chloride (PVC) (the thermoplastic element) covering one or more individual cables which are PVC insulated annealed copper conductors. It is a commonly used type of wiring for residential and light commercial construction in many countries. The flat version of the cable with two insulated conductors and an uninsulated earth conductor all within the outer sheath is referred to as twin and earth. In mainland Europe, a round equivalent is more common. Flat cables (or festoon cables) are made in PVC and Neoprene and are used as trailing cables for cranes, open filed conveyors and shelve service devices. Flat cables offer the advantages of extremely small bending radius’s, high flexibility and minimum wastage of space.
