Student Learning Outcomes

  • The student will learn the safe and approved methods using over current protection for residential wiring installation
  • the student will learn the National Electrical Code on grounding a single family dwelling

Description

Intended for apprentices to become trained in electrical grounding and bonding. Focus will be on learning the electrical code and overcurrent protective devices (OCPD). Apprentices will demonstrate their ability to read residential, commercial, and industrial blueprints and to perform circuit layouts. This course meets the requirements of electrical safety standards for 3rd year apprentices who are pursuing their certificate.

Course Objectives

The student will be able to:
A. Correctly ground and bond electrical equipment
B. Correctly size grounded and bonding conductors
C. Perform sizing for over current protection
D. Identify the different types of fuses and breakers
E. Read blueprints and understand job costs and takeoffs
F. Install and connect a transformer
G. Apply harmonics on a circuit
H. Recognize arc flash hazards and how to correct them
