G.O. 95 and NESC Compliant Overhead Distribution Line Design Online Training Program
September 9-11, 16-18, 2025 9:00 am to 12:30 pm (Pacific) each day
The State of California has established legislation and the California Public Utilities Commission (CPUC) has issued General Order (G.O.) 95 Rules for Overhead Line Construction and General Order (G.O.) 128 Rules for Underground Line Construction. California’s public and private electric utilities are required to comply with these general orders. Engineers and designers, as well as operation and maintenance employees of utilities and their contractors are expected to understand and properly apply these rules.
Participants will receive copies of the presentation materials in advance, allowing you to work with them before, during and after the online sessions. The scheduled online sessions will also be recorded and available for a period of thirty days, enabling participants to work around any scheduling conflicts.
LEARNING METHODS This program is applications‐oriented, including group interaction, high‐quality presentations, Q&A, and opportunities to check all that you have learned.
WHO SHOULD PARTICIPATE? This workshop has value for those who work at all levels of overhead distribution line design and should be attended by: • Engineering managers • Design/staking technicians • Design engineers • Resident engineers • Design/staking supervisors • Consulting engineers
DAILY SESSION SCHEDULE: This program will be presented in six (6) “live” half-day sessions. Following each session, participants are expected to work independently on exercises related to the topics presented.

Underground distribution continues to be the installation method of choice in many applications on public power systems. Although the initial installation cost of underground distribution is almost always greater than equivalent overhead distribution, it offers a wide range of advantages including greater operating reliability, lower operating and maintenance costs, better public safety and, of course, reduced visibility and greater public acceptance.
Learn how to improve your utility’s policies, standards, and practices for planning, designing, constructing, operating, and maintaining underground distribution and hear about current and emerging industry trends.
Ensuring long-life cable installations
Civil engineering considerations in underground distribution
Professional practice in utility underground line design
