Prerequisites: EPC 1080 - Residential Wiring Basic & Lab 

Course Description:
This course guides students room by room, through the wiring of a typical residence. By staring with the basic requirements of the National Electrical Code (NEC), then continuing on to the more advanced wiring methods. Also provides the basics of commercial wiring by offering insights into the planning of a typical commercial installation, demonstrating how the load requirements are converted into branch circuits, then to feeders, and finally into the buildings main electrical service.
