[Elect117]

Chapter 1910 sounds beachy.

I don't understand why they are going to move around the communication cable's section. I just know people are going to get that mixed up.

I would also suggest moving interconnected systems and energy systems further towards utilization equipment. It always sucks flipping from 690 to 310 to 240to 408 to 705, and again. It makes all of that way more confusing than it should be.

 

[don_resqcapt19]

That will not happen for the 2026. It has been pushed off to at least the 2029, however there will be some changes working toward this in the 2026.
The is a fair amount of opposition to this reorganization, and even though the NFPA insists it will happen, it is still up to the vote of the membership at the annual meeting when the NEC is adopted.

 

[tortuga]

I think more of the tens place numbering should follow the old, like motors section should be 1230 not 1226.
Perhaps such a big reorganization should be all that changes that code year, other than urgent changes.

 

[jaggedben]

I'm gonne hate typing an extra digit all the time.
Chapter 19 should be Chapter 4.
Chapters 18 and 20 should come before Chapters 13 through 17, and 17 should come before 13 through 16.
I don't agree with dividing wiring methods into five Chapters.

 

[jaggedben]

Article 230 should be grouped with Chapter 19 in an article called something like 'Power Source Connections'. But be, like, Chapter 3 or 4.

 

[hbiss]

Won't be able to say anymore that a Class 1 circuit requires a Chapter 3 wiring method. Also, where's the dividing line like there was between Article 725 and the Articles below it?

Any references to other Articles are all going to have to be revised to reflect the new Articles.

[zbang]

Now if they would cut the word count by 20-25% in the process, they'd have something.

 

[brycenesbitt]

Energy Storage Systems, Electric Vehicle Power Transfer System and Electrified Truck Parking Spaces
have a lot of overlap, and will have more with bidirectional charging.
-
One issue I have with reading code is the authorship is split up by code committees. So the same thought, rightfully repeated in each section, is expressed in different words. Or duplicated text is revised in one place but not similar places.
...
Some sort of tracking of changes that should ripple would be nice.

 

[Hv&Lv]

There is a fair amount of opposition to this reorganization,

That’s because 95% of the electricians are too old to learn a new system..

If it goes to the 29, I for one won’t care about it at that time. It could be 2035-2045 before states adopt it..

I think it is more in terms of the hundreds of millions of dollars in educational materials and training that will be required for the proposed reorganization.
There are plenty of ways to add the required new material without relocating pretty much every rule in the book.
