2026 Code Discussion

Submitted by Mile Miller, Curriculum & Training Manager

It’s the time of year where we settle back and enjoy the winter and perhaps take time to read those newsletters from the many organizations we receive them from. This publication in  front of you may prove to be worth the time it takes to read it because any one who’s licensed knows how important it is to follow the NEC.

By now, many of you have probably noticed how relatively uneventful the 2026 NEC feels compared to past editions. Think back to the 2020 Code, when costly expansions of AFCI and GFCI requirements in dwelling units stirred plenty of debate—changes that many felt were unnecessary and that fueled a long history of resistance, delays in adoption, and arguments over cost and practicality. In the end, both of those suggested changes were adopted, though they remain a sore spot for many even today. In some ways, we should be grateful for how brief this cycle feels and celebrate the fact that there’s less to memorize. Maybe it’s a sign that, after all these years, the code‑making panels finally got most of it right in the last revision.

Not to stir the pot, I thought I would share a list of the top six code changes in my mind that will make a difference in our wiring practices.

The Top Six

1.  Arc‑Flash Hazard Marking (110.16)

I think this challenge is going to be the most difficult to comply with because of calculations required to make this may require engineer’s expertise. Currently there is no app available for incident energy levels like there were for calculating available fault current.

2.  Spaces Around Electrical Equipment (110.26)

Here we find clearance rules are critical for installation and service. Masters and journeymen will feel this immediately when laying out panels or troubleshooting.

3.   Expanded Disconnect Rules (110.26(C)(2))

Extending requirements to feeder disconnects changes how larger systems are designed and installed. This is a planning and compliance priority

4.  Manufacturer’s Instructions (110.3(B))

Reinforces that “field fixes” or shortcuts aren’t acceptable. Journeymen especially need to be mindful of this in daily installs.

5.  Limitations (of wiring)  300.4(C)

Conductors and wiring methods that are no longer suitable for use due to damage, such as overheating, fire damage, corrosive influences, or water, shall be replaced. The important part, and sometimes debatable part  about this section is - who bears the responsibility to repair it and pay for it.

6. Article 210.8(F) Exception No.2   

GFCI protection shall not be required for listed HVAC equipment. This exception shall expire September 1, 2026, is still slated to be withdrawn on  09/01/2026. The exception expiration will make necessary GFCI protection for HVAC equipment outside a dwelling unit.  Perhaps a ray of hope lies on the horizon with the introduction of a type HF or HF+ GFCI circuit breaker. The industry is gearing up this requirement.
