The objective for this course is to expose attendees to the process of designing and dealing with issues associated with distribution circuit construction, both overhead and underground. The curriculum references applicable National Electric Safety Code (NESC) requirements and provides interpretation when necessary. This course will offer a comprehensive and interactive format to discuss everything from the basics of the distribution system to design standards, practices, and solutions to key challenges in the commercial and residential spaces.

Learning Outcomes

  • Review contemporary National Electric Safety Code (NESC) mandates including scope, purpose, and revision scheduleProvide an overview of the Power System as well as key electrical terms
  • Identify Common Formulas for a distribution line Design
  • Cover major considerations for Electric Overhead Line Design including NESC Grades B&C Construction
  • Discuss Distribution Overhead Components including conductors, transformers, poles, guying, and crossarms
  • Cover major considerations for Electric Distribution Underground Line Design including Part 3 NESC, riser poles, and cable and terminationsCover a comprehensive analysis on the unique design features for both commercial and residential service applications.
