Washington NEC Code Changes — Conduit Sizing, Box Fill, and Pull Boxes

Four of your Washington NEC-code hours, spent on the calculations you look up most and check hardest — raceway sizing, box fill, and pull boxes, from the 2023 National Electrical Code to the 2026 edition.

  • Approved by the state. The Washington State Department of Labor and Industries (L&I) approved this course on September 1, 2026 as course WA2026-553, in the NEC-code-changes category, for 4 hours. Trade Code Solutions LLC is the approved sponsor, number 3291. L&I approved it as an internet course, so taking it online is how it was filed.
  • Watch, learn, done. Washington measures this class in time in the seat, not a test score. Finish all four hours and you're done — no exam at the end.
  • We handle the paperwork. Trade Code Solutions posts your completion to L&I for you — Washington's rule gives sponsors 7days to post it — and your certificate of completion is issued as soon as you finish.
  • Taught from the code itself. Every change checked line by line against the published NEC 2023 and NEC 2026 — not a summary of a summary.

One sitting or many — your progress saves. Certificate of completion included. Your certificate renewal fee is paid to the State of Washington separately.

How it worksWatch in order, confirm it’s you, done

The course plays in order, start to finish — that's how Washington wants continuing education delivered, and it's how your hours hold up if the state ever asks. Along the way we'll pause a few times and ask you to confirm your name and certificate number, so the record shows it was you in the seat the whole time.

Washington counts a continuing-education hour as 60 minutes, so the certificate issues after 240minutes of instruction time. When you finish, two things happen: your certificate of completion is issued to you, and your completion is posted to L&I — you don't file anything yourself.

Have your Washington certificate or license number handy when you enroll. We ask for it at checkout so your hours are posted against the right certificate. We never ask for a Social Security number.

What’s coveredFour hours, four parts

Raceways, boxes, and grounding conductors, from the 2023 book to the 2026 book.

  1. Wiring Methods and Conductors. Article 300 protection and corrosion rules, free conductor length, the Article 310 layout, conductors in parallel, ambient and conductor-count adjustment, Table 310.16, and cabinets and cutout boxes.
  2. Boxes and Box Fill. Article 314 scope, box volume, and all six box-fill allowances — conductor, clamp, support fitting, device, equipment grounding conductor, and terminal block — with worked examples.
  3. Pull and Junction Boxes, Wireways, and Conduit Fill. Straight, angle and U pulls, listed conduit bodies, box supports, metal and nonmetallic wireways, Chapter 9 Notes and Tables 1, 4 and 5, nipples, and Annex C.
  4. Equipment Grounding Conductor Sizing and Putting the Raceway Together. Table 250.122, upsized phase conductors, the 2026 relief for parallel raceways, and mixed worked examples that run a raceway, a box and a grounding conductor end to end.
Who it’s forWashington certificate holders on the 24-hour cycle

Washington certificate holders who renew on 24 hours every 3 years:

  • Electricians holding a Washington certificate of competency.
  • Master electricians.
  • Electrical administrators.

Not for trainees. Washington puts electrical trainees on a separate basic-classroom requirement and does not let trainees use internet or correspondence classes for it, so this course won't count for a trainee.

Common questions7 answers
Is this course approved in Washington?
Yes. The Washington State Department of Labor and Industries — L&I — approved it on September 1, 2026 as course WA2026-553, in the NEC-code-changes category, for 4 hours. Trade Code Solutions LLC is the approved sponsor, number 3291. The approval runs through September 1, 2029, and L&I approved it as an internet course, so taking it online is exactly how it was filed.
What kind of hours does this cover?
NEC-code hours — a different category from Washington's industry-related hours. Washington asks for 24 hours every 3 years: at least 8 on changes in the currently adopted National Electrical Code, at least 4 on Washington law and rules, and the remaining 12 on approved industry-related subjects. This course is 4 of those NEC-code hours. Paired with its companion course on overcurrent protection, the two together cover the full 8-hour NEC-code minimum.
Is there an exam at the end?
No. Washington measures this class in time in the seat, not a test score. Watch all four hours in order, confirm your identity at the checkpoints, and you're done.
How do my hours get reported to L&I?
Trade Code Solutions posts your completion to L&I's roster system for you. Washington's rule gives sponsors 7 days to post it, so there is nothing for you to file. Have your Washington certificate or license number ready when you enroll; that is how L&I matches the hours to you.
Can I take this class again next cycle?
Not within the same cycle. Washington will not give you credit for the same class twice in one 3-year cycle, so plan this one as 4 of your NEC-code hours rather than a repeat.
How long does it actually take?
Washington counts a continuing-education hour as 60 minutes, so the course runs 240 minutes of instruction time before the certificate can issue. You can take it in one sitting or many — your progress saves.
Do I need to take the companion course too?
Not to take this one — each is a complete 4-hour class on its own and stands alone on your certificate. But if you still need the rest of your 8-hour NEC-code requirement, the companion course covers overcurrent protection — the other half of the 2023-to-2026 code changes.

Working through the rest of your NEC-code hours? NEC Code Changes — Overcurrent Protection covers the other half.

Four hours that make the raceway math match the 2026 book.
