EV charger run neutral or not dilemma

[tortuga]

Hold on Seirra, dont waste that money, The last Tesla charger I did was called a "wall connector" and I hard wired right into it.
My understanding is all car chargers use a single voltage as in '240' volt, we dont use a 14-50 or pull a neutral.
Others I have put on a 6-50 recept.
EDIT: You program them to whatever breaker they are on
From the manual:

Yes that is the concern. I originally sold the customer on a 6-30 receptacle , then they wanted to have the wire upgraded to plan for the future in case they had a service upgrade as a 50 would be marginal depending on which method you use as a load Cal ( using Mike Holt spreadsheet)
Then the customer says that Telsa does not sell a 6-30 adapter. However a aftermarket does.
Now the plan is to use #8 for the future pull the wasted neutral and charge for it. Install a 14-30 receptacle. How frikin stupid can Tesla and the rest be. This is gonna cost a about 100 bucks for a wire that should not need to be there.

I know they have many adapters but didn't realize they didn't offer a 6-30. Just looked and they have 6-15, 6-20 and then jump to 6-50. Makes no sense to also offer the 30. I would bet more 30's would get purchased over 15s and 20's.

The OP is installing a receptacle for the standard charge cord that comes with the car. You just have to purchase a ~$50 apapter to match the receptacle installed. A wall connector is a seperate item than has to be purchased separately for around $600.

Ahh ok did not catch that. Every Tesla owner I have worked for got that 'wall connector' unit.

If one 6-50 Plug whip works for most 240v level-2 car chargers, per 210.21(B), it makes sense to skip the 6-30.

However, before => 48 Amp chargers existed, trying to source a listed NEMA 6-50P whip was an exercise in futility.

Especially if you wanted a plug listed for 50A continuous use. By now counterfeit / unlisted 6-50P whips may be online, perhaps most likely to melt down near 48 Amps.

Cord & plug versions of L2 chargers were always shipped with listed 14-50P whips, even though neutral prongs are never used.

The subsequent inspection failures was not anticipated, by listing-centric inspectors demanding a neutral wire with that 14-50 configuration.

The hard-wired "Wall connector" L2 solution solves this problem when installed by qualified persons, unless cord & plug is preferred by clients.

I'm one who believes that it's irresponsible to leave a neutral receptacle terminal left floating.

While the expected load may not require it, other loads, such as an RV cord, certainly would.
