So, in Beaumont, Ca. the local official is regarding an EV charger as an permanently installed appliance as in 422.31 requiring a disconnect. My argument is that 625.43 is that only over 60 amps is a disconnect required as 625 is an EV specific code. This guy also believes that over 150 to ground relates to 240v outlets. I explained to him that is about 277/480v circuits. I only wish is that one of the authors of this article could reply as I actually had one reply to me before on a PV solar question.
Meanwhile I guess I'm adding a disconnect.
 
Chapter 6 should take precedence over Chapter 4. See 90.3. See also Article 100 definition of Voltage to Ground. Sounds like you are dealing with someone who is that knowledgeable. If you have cited these sections to him then I guess he's also not very reasonable. Good luck.
 
An EV "charger" is not a charger. The charger is on board the vehicle. What we are installing for your typical home is a "Electric Vehicle Source Equipement" it is not an appliance as is does no work nor does it convert the current or voltage. It is merely a connector to the vehicle.
 
You are correct about 625.43.

Equipment rated more than 60A

or

120V or more to ground

Now the issue is whether or not 240V is qualified as "120V or more to ground".

I can only thing of one instance where it would be. That would be on a 240V 3PH system. And then it would be phase specific.

To be honest, I have heard of local AHJs in CA asking for disconnects hear or at the EV charger. I just haven't experienced it yet myself.

Agreed a EVSE is a close cousin to a drop pendant receptacle that got special protection added. Not an appliance

Now he says I should read 90.4, basically saying I'm the authority here.
 
This won't help but you're dealing with an idiot that doesn't understand 90.4
 
On your 120/240 circuit what would your meter read on your L1 or L2 to ground? That is your answer as to whether it exceeds 150V to ground, simple.
 
Just a quick FYI; IMHO, consenting to something that is clearly NOT required by the NEC (as adopted in your area) is giving the cowboy inspector more reasons to request other contractors to "DO IT".

This discussion went thru my office with one of my inspectors re: "Appliance". A EVSE is NOT an appliance use Article 625,
