Virtual Training
Overhead Distribution
Principles and Applications

Join us as we hold this popular course as a series of five interactive virtual sessions. It’s a convenient way to 'attend' the course, while still having the opportunity to interact with the instructors, your industry peers, and earn 14 PDH credits. This course is applications-oriented, including online lecture, interaction, and learning by doing. 

Learn about the characteristics and functions of overhead distribution components and the legal/regulatory/business requirements that drive today’s overhead distribution practices. Explore specific requirements and practices associated with overhead line conductors and cables, structural components, grounding, and lightning protection.

Learning Environment

All sessions incorporate real-time presentations from industry experts, Q&A, group interaction, and hands-on exercises. 


Participate in a 45-minute orientation session on January 14, followed by five, real-time sessions from Noon – 4 p.m. Eastern on January 18, 19, 20, 25 and 26. There will be two 15-minute breaks incorporated into each session.

Course Overview

Overhead distribution continues to play an essential role for most utilities in delivering electric service to end-use customers, either directly or as the source for underground line extensions. Learn about the characteristics and functions of the various components that comprise the overhead distribution system as well as the legal/regulatory and business requirements that drive today’s overhead distribution practices. 

Explore specific requirements and practices associated with overhead line conductors and cables, structural components, grounding, and lightning protection. Learn how to review and improve your utility’s overhead line design criteria and construction standards, make better design decisions, and enhance safety and service reliability. 

Recommended For

Those who work at all levels of overhead distribution design including:
Engineering managers
Design engineers 
Design/staking supervisors and technicians
Consulting engineers
Crew supervisors and senior lineworkers 

Those who are relatively inexperienced in the industry or to overhead distribution, as well as those with experience who want to “refresh and update” their understanding of underlying principles, practices, and the components and equipment that comprise today’s overhead distribution system will benefit from participating.

It is highly recommended that you attend this course in conjunction with the Best Practices in Overhead Distribution Line Design online course February 15-23, 2022.

Sample Agenda/Learning Outcomes  -  Coming soon!

Course Level

Basic/Intermediate: No prerequisites, though some advance preparation is requested, including attending an orientation session on January 14 (1-1:45 p.m. Eastern – this will be recorded) and completing a brief pre-course survey. 

For those looking for more comprehensive training, it is highly recommended that you attend this course in conjunction with the Best Practices in Overhead Distribution Line Design online course (Feb. 15-23).

Technology Requirements

Zoom Meeting Application: Attendees are required to have strong Internet access, in order to run the Zoom meeting platform. Click here to learn more about downloading the Zoom Web Client.

Audio/Webcam: You will need to enable computer audio to listen and speak (alternatively a call-in number will be provided) and you will also need a webcam, so you can fully engage in the small group breakout session and group discussions.

Additional Requirements

2017 NESC: Participants are required to have a copy of the 2017 National Electric Safety Code®(ANSI C2-2017) on hand to review during the course. Hard copies and electronic version can be purchased from IEEE (; 800/701-4333).

Course Access and Materials

Zoom Links: Zoom log in credentials will be sent out 24 hours before the start of Session 1.

Course materials: Attendees will receive access to APPA’s secure online document portal a week before the course, where the eManuals and other course materials will be made available, allowing you to work with them before, during and after the online sessions. 

Recordings: The sessions will be recorded and can also be accessed through APPA’s document portal (within a week of the last class in the program), in case you can’t attend the live versions. Recordings will be accessible for 90 days after the last course session. Note: Continuing education credits can only be issued for attending live sessions.

Application Exercises/Homework

Following each live session, participants are expected to either complete a quiz (to test your knowledge on key concepts) or work independently on line design application exercises (some exercises will be conducted during the live sessions). 

Further instructions will be provided at the beginning of Session One. The estimated time for completing these items is up to 1 hour per class day.


The following continuing education credits will be provided, after successfully completing 90% of all five live sessions. Certificates will available by Feb. 9. These sessions will be recorded, though certificates can only be awarded to those who participate in the live events (click here to review requirements).
