If you have no formal electrical engineering education, this course will teach you how electrical distribution systems for commercial and industrial buildings are designed and operated. Emphasizing basic electrical concepts rather than rigorous mathematical derivations, expert instructors introduce the fundamental direct current concepts and extend them to single-phase and three-phase alternating current systems. After completing this course you will know how to design low voltage (1,000 volts and below) electrical distribution systems and you will have a sound understanding of the associated codes and standards, as well as the important grounding, power quality, and arc-flash issues.

• Working professionals who design electrical systems but who do not have a formal electrical engineering degree
• Plant engineers
• Electrical contractors
• Utility engineers
• Others responsible for the electrical and lighting systems in manufacturing plants and commercial and institutional buildings

This course has been approved by the State of WI Department of Safety and Professional Services (DSPS) for 35 hours for: Commercial Electrical Inspector, Industrial Journeyman Electrician, Journeyman Electrician, Master Electrician, and Registered Electrician license holders.
