2026 NEC® Changes: Conductors and General Requirements for Wiring Methods

2026 NEC® Changes: Conductors and General Requirements for Wiring Methods

1 hr. Online Course

Level: Intermediate

Item#: JCOM-00149

SME: Ryan Jackson

This course provides an overview of the 2026 NEC® updates to Article 300 and general wiring methods, with emphasis on practical application in field installations. Topics include revised scope provisions, when wiring methods must be replaced, installations beneath roof decks, raceway sealing for temperature conditions, and requirements for aboveground raceways in wet locations.

 

Participants will also review approved securing methods, including NEC®-recognized cable ties, fittings used in lieu of boxes, prohibitions on raceway welding, and allowable bends. Additional coverage includes conductor requirements such as listing standards, minimum sizing, sunlight resistance, grounding electrode installation sequence, ampacity adjustment and temperature correction exceptions, and Table 310.16 values for small conductors. Upon completion, participants are prepared to apply updated NEC® wiring method and conductor requirements.

Course Objectives

By the end of this course, you'll be able to:

  • Describe the scope changes to Article 300.
  • Explain when the NEC® requires wiring methods to be replaced.
  • List the requirements for equipment beneath roof decks.
  • Explain the rules for sealing raceways exposed to different temperatures.
  • Recall what is required for above-ground raceways in wet locations.
  • List the types of cable ties and cable tie fixing devices that the NEC® recognizes.
  • Describe the requirements for fittings used in lieu of boxes.
  • Discuss the prohibition of welding raceways.
  • Recall how many bends are allowed in raceway installations.
  • Describe the listing requirements for conductors in the NEC®.
  • Recall the minimum conductor sizes allowed in the NEC®.
  • Explain when conductors require sunlight resistance.
  • Describe the allowance for ignoring ampacity adjustment and temperature correction.
  • Recall the ampacity for small conductors in Table 310.16.

Ryan Jackson Photo
Ryan Jackson is a combination inspector in the Salt Lake City, Utah, area. He began his career as a carpenter while in high school, and began doing electrical work at the age of 18. At the age of 23 Ryan landed his first job as an electrical inspector, and subsequently became certified in building, plumbing, and mechanical inspection, as well as building and electrical plan review. Two years after becoming an inspector, he was approached by a friend in the area asking him to fill in at an electrical seminar for him. After his first class he was hooked, and is now a highly sought after seminar instructor. Ryan has taught in several states, and loves helping people increase their understanding of the Code.

 

He has been involved in writing and editing over 25 books on the National Electrical Code, and has taught the subject in multiple states and for multiple colleges and universities. He is self-employed as an NEC® consultant and inspector.

 
When Ryan isn’t working, he can often be found in his garage turning wood on his lathe, in his basement exercising, or any quiet place where he can dive into a book. He is also a rabid University of Utah football fan. Ryan married his high school sweetheart, Sharie, and they have two beautiful children together: Kaitlynn and Aaron.
