Course Description

This course introduces residential wiring practices and procedures. Topics include residential circuits; National Electrical Code; wiring materials; determining the required number and location of lights, receptacles, and small appliance circuits; wiring methods (size and type of conductors, box fill calculations, and voltage drop); switch control of luminaries; receptacle installation including bonding; GFCI and AFCI circuits; special purposes outlets (ranges, cook tops, ovens, dryers, water heaters, sump pumps); and sizing OCPDs (circuit breakers and fuses). Students must pay a $30 supply fee when registering for this course.
