Best Practices in Overhead Distribution Line Design
November 28, 29, 30, December 5 & 6, 2023
12:00-4:00 PM Eastern
Plus a required orientation session November 27, 1-1:45 PM.
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.
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 November 27, followed by five, real-time sessions from Noon – 4 p.m. Eastern on November 28, 29, 30, December 5 and 6, 2023. There will be two 15-minute breaks incorporated into each session.
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. Overhead line design is an engineering discipline that requires the consistent and proper application of engineering principles and ethics to prepare quality designs and reduce liability exposure.
Learn how to enhance your line design processes and prepare designs that are safe, reliable, and in compliance with National Electrical Safety Code (NESC) requirements. Review industry best practices, engage with your peers, and complete over twenty-five (25) practical hands-on design exercises using line design software.
Attendees will return to their work better prepared to help their organizations adopt design practices that comply with applicable professional engineering laws and regulations.
Note: Some of the exercises will require the use of line design software, which you’ll receive complimentary access to for a period of thirty (30) days from the start of the course.
Recommended ForThose 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
Overhead Distribution System
Principles and Applications Online Course
September 19, 20, 21, 26 & 27, 2023.

- NESC and practical requirements for maximum conductor/cable design tension
- Conductor/cable sag and tension calculations, sag-tension software, and application examples/exercises
Session 3: NESC Clearance Requirements
- Clearances to ground and water surfaces; buildings and other structures; and between conductors, cables and equipment
- Selected special clearance conditions and application examples/exercises
Session 4: Overhead Line Structure Loading and Strength (Part 1)
- NESC requirements for supporting structure design (loading conditions and strength requirements)
- Determination of mechanical forces on supporting structures
- Overhead line guying and anchoring design considerations
- Supporting structure loading application examples and assigned exercises
Session 5: Overhead Line Structure Loading and Strength (Part 2)
- Wood poles (types, treatments, dimensions, strength classes, and specifications)
- Manufactured poles (types, characteristics, NESC equivalent designs, and specifications
- Pole embedment designs
- Supporting structure loading application examples and assigned exercises
Intermediate/Advanced: No prerequisites; however, completion of the Overhead Distribution Principles and Applications (September 19, 20, 21, 26, 27) is highly recommended. Discounts apply for attending both.
Some advanced preparation is requested, including attending an orientation session on November 27 (1-1:45 p.m. Eastern – this will be recorded), completing a brief pre-course survey, and logging into the line design software platform.
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.
2023 NESC: Participants are required to have a copy of the 2023 National Electric Safety Code® (ANSI C2-2023) on hand to review during the course. Hard copies and electronic version can be purchased from IEEE (www.ieee.org; 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.
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. These sessions will be recorded, though certificates can only be awarded to those who participate in the live events (click here to review requirements).
