“The training is thorough and relevant. All the course materials are top notch. I still use them long after the course is over.” – Senior Engineer, NES

“Good course. Very informative. The guys know their stuff.” DSiP Rep, Black Hills Energy

“As a nationally renowned NEC Code Expert I highly recommend all Electricians attend to gain a better knowledge of the utility side of the industry.” Manager of Codes & Standards, Encore Wire Corp.

More communities are seeking to underground existing overhead electrical distribution lines for a variety of reasons such as: reliability/storm hardening, visual reasons, new construction requirements and more. This course will review the fundamentals of underground distribution feeder design and operation by providing an in-depth look at underground systems, technology, construction, and operation. This is the ideal course for engineers and project managers new to underground distribution projects or anyone looking for a more in-depth look at underground distribution systems.

Learning Outcomes

  • Expand on the various loop feed configurations used in underground systems
  • Discuss the major material types used, when and why they are used in underground systems
  • Review conductor types, applications and connecting systems used in underground systems
  • List the differences, features, types and applications of distribution transformers
  • Define the various type of pad-mount equipment and their applications
  • Review the design and operation safety requirements for underground systems
  • Discuss the typical fault types and other problematic issues for underground systems
