Commercial Wiring Methods

Prerequisite: ELEC101 & ELEC102. This course introduces three-phase circuits and the key practices used in commercial wiring. In the lab, students will work with commercial plan sets, size feeders and branch circuits, select conductors, bend EMT, assemble panelboards, install raceways and cable trays. They'll also learn to apply demand factors and selective coordination when specifying fuses and breakers. Completing this course prepares students to help with light commercial projects and communicate clearly with engineers, inspectors, and general contractors.
