Intended Outcomes for the course

Upon completion of the course students should be able to:

  1. Display and use an introductory knowledge of basic atomic theory, electrical theory, conductors, insulators, wiring methods, wire sizing, common electrical devices, electrical panels, over-current protection, and code requirements when wiring in a residential setting.
  2. Identify and use the most common hand tools and power tools used in residential wiring.
  3. Display and use an introductory knowledge of common electrical switches and circuits when wiring in a residential setting.
  4. Display and use an introductory knowledge of schematic diagrams, wiring diagrams, electrical circuits, amps, ohms, volts, and watts when wiring in a residential setting.
  5. Work safely per NEC and OSHA requirements when wiring in a residential setting.

Course Activities and Design

The majority of the course will be Lecture accompanied by demonstrations of wiring practices per the requirements of the NEC

Outcome Assessment Strategies

Assessment will be accomplished through the completion of specific wiring projects applicable to Residential wiring
