Tesla EV charger/eaton breakers

Exception#2 is unenforceable. What is the definition of "unwanted tripping". What does it mean to inform the manufacturer? Do you need to give the manufacturer time to correct the issues. or can you replace the breaker immediately after notification?

Many states have similar exemptions where GFCI' or AFCI's can be omitted, I bet @wwhitney could write it up professionally and summit a PI, indeed that was no final draft just getting the idea out there.
Someone on here was posting about MA has a standard form for unwanted tripping an electrician can fill out ?

The current exception in Oregon reads as follows:
210.12 Exception No. 3: AFCI protection shall not be required for optional, dedicated outlets that supply equipment
known to cause unwanted tripping of AFCI devices.

I never had to use the exception but its there and I am sure EC's use it, all thats required is the EC to state its 'known to cause unwanted tripping' So I doubt they would want more than that from a similar proposal. We'll see.

No they aren't. They are just showing adoption in different states.

Can you provide a list of states the accepted AFCI's and GFCI's as part of their code then removed them?

Also some states don't have a state wide code adoption, its up to the local jurisdictions.

Chicago Electrical Code removed AFCI from the code. Department of Housing projects still requires them in the City of Chicago though (sleeping areas).

Probably because Chicago is all EMT and 12 AWG minimum in residential right? Or is that NYC? or both?
Seems there is a good study to be had there, I bet looking into that would justify an full exemption from AFCI on circuits in EMT with 12 AWG cu.
 
I thought the original reason for AFCIs was to protect against damaged lamp cords. Matter of fact the UL test setup uses a piece of lamp cord for the test. Nothing to do with wiring and conduit which still has splices and wiring devices.

Chicago at least.
There used to be a few feet of romex going to a GFCI device in a Cook county house. Somebody's Grandmother needed one in her bathroom.

When they first came out, I was taking a continuing education class for one of my licenses, the teacher used a knife on a hing to cut a lamp cord, showing it didn’t work. Not real scientific, but the same teacher said running 3/0 to a stove would pay for itself in voltage drop heat savings in two years! LOL!

Funny you state that. That is the exact reason for the exception.

Exception No. 1 to 210.12(A), (B), and (C): It shall be permitted to omit AFCI protection
for that portion of the branch circuit enclosed in rigid metal conduit (RMC), intermediate
metal conduit (IMC), electrical metal tubing (EMT), or Type MI cable sheath meeting
the requirements of 250.118 along with metal outlet and junction boxes.

No Romex allowed in Chicago. So as long as it's installed in metal pipe, you don't need it. No minimum wire size here. Department of Housing still requires them in the sleeping areas, which tell me that they think it's floor lamps. They ALSO require a switched ceiling fixture (not switched outlet) in sleeping areas. I argued with them that if they required an overhead light, then why do they also need AFCI because there wouldn't be an abundance of floor lamps. They wouldn't budge. They didn't say it directly, but DOH projects are generally low income where people may not have the best functioning equipment. However, as long as funding doesn't come from DOH, then you don't need either AFCI or switched fixtures.
