NEC code changes

The NEC has made changes to the electrical code that may be of importance to all installers.
There are many changes, but these are of interest:
Any changes from the utility meter to the main must have a exterior disconnect installed.
All double pole breakers must be GFCI type.
AC, dryers, garages, etc.
Installing and ATS will require these changes to meet code.
Of course I did not post all of the changes, so beware before you make a change and find out you goofed.

Can you site some of these codes? I have never heard of the GFCI code change for 240V applications. Would also make a multi-wire branch circuit applicable as well since it is 2-pole. Is this the 2023 code cycle?

I do not have a recent code book.
A friend (licensed) told me of the changes he was schooled on.
I did dig up one video,
The video covers the 240 volt breakers.

I talked with a builder that does his own wiring and he was not aware of this change either.

A friend of mine who does a TON of code related content, Ryan Jackson (look him up, VERY knowledgeable guy) and I were talking about this and he did confirm this. Sounds like basically they lifted the voltage and amperage requirements for the outlets which were already required to be GFCI protected in laundry areas, unfinished basements, kitchens (within 6' of water) etc.

Imagine what a panel full of GFCI 240V breakers is going to cost
