2026 National Electrical Code (NEC®) Changes: PV, ESS, EVs, PCS, and More

About this course

The 2026 version of the National Electrical Code (NEC®) introduces many important changes that impact the design, installation, and operation of PV systems, energy storage systems (ESS), EV supply equipment (EVSE), energy management systems (EMS), and power control systems (PCS). Learn from experts involved in writing the most important sections of the Code that cover these evolving installations that are the future of electrical systems: Code-Making Panels 4 and 13. This course focuses on the most recent changes and additions since the 2023 version.

This course only covers changes and updates in the 2026 NEC®. We will release a longer course that takes a deep-dive into all NEC® requirements, including these changes, that are applicable to these systems and equipment. Students who take this "changes and updates only" course can apply the cost of this course to the longer format one when it comes out. Students will be notified when the longer course is released and will coordinate with support@heatspring.com to apply the credit.
