New Wall Connector :)

[omarsultan]

#sigh

Just added a 50A circuit and a second HPWC for the new Model X -- this would have been a better choice approach, since it would allow me to share the existing 100A circuit from my first HPWC.

Read through the manual, which left me with a couple of questions -- Calling @FlasherZ !

1. The rotary switch tops out at 63A - why? Should it top out at 72A to match the new chargers?
2. Does the NEC have opinions on daisy-chaining EVSEs on a single circuit is there is a control mechanism in place?

This is for non-U.S markets so the amperage could be different

I guess, but that would imply non-US markets top out at a 63A on-board charger too? Was 80A not an option in non-US markets?

I think you might be looking at the wrong manual. Have a look at post #8 in this thread, page 21, I see 80A on a 100A breaker.

I was indeed - thank you.

Wow, $550 for the new version with 24ft cord on the online store. That is similar to 32 amp J1772 charger prices. Add in daisy chain capability and it seems like a steal. I hope lots of places get these installed. Seems like it would make deploying lots of L2 charging much easier/cheaper.

 

[McManX]

Ordered. Surprised price dropped, thought it was going to go back up to $1k.

 

[K-MTG]

I just payed $750 for mine and got it installed!!!!! At least I can justify my current one since I don't have enough room to mount the connector on the side.

 

[K-MTG]

Any features that make it worth the upgrade?

I bought an 'old' one about a week ago but electrician is still working on upgrading the panel. Figure I will either return that or just install it at my vacation home.

Ordered the 24' one, says 3 week wait. The shorter one says 5-7 days.

Just ordered the 24 foot one. Now I can finish my charging station with HPWC and NEMA 14-50 on a 100 amp circuit.

 

[K-MTG]

I wonder if they can just refund me $250

Well done Tesla ... the HPWC is now $100-$150 cheaper than the UMC.

Flasher can you talk a little more about what you think or know (be clear on which...) re: master/slave relationship. For an owner with multiple cars, I presume this buys you the ability to have multiple cars plugged in (physically) and the chain of HPWCs connected to a single 100A circuit. Does this mean the HPWCs charge one car at a time (without "fiddling" with connectors)? Can you also "make it smart" such that you charge them at the same time -- say 70A + 10A?

The manual doesn't address it unfortunately, I'm reaching back to get some clarification on how that works. I'm guessing we're looking at one of two scenarios -- either it sequentially serves cars at full rate, or adjusts to load share equally across multiple cars that need it.

Would this allow for some lighting circuits to be augmented with these chargers? My first guess is no, since those parking lot lights are probably designed for particular loads, but if they exchanged those lamps with LED lamps, and/or pulled fresh large wires as McRat described (if the conduit allowed) would that allow for some circuits to have this most recent Tesla Wall Connector attached as McRat described?

Yes, it could. This would allow companies to install Tesla chargers in the main (3-phase, 480V/277Y) panels and avoid the need for step-down distribution transformers that are required for 120V / 240V loads.

But don't expect someone to slap these on the same wires going to poles -- you'll need to run new circuits to put these in parking lots. But at least it will not require yet another transformer to add them.

The NEC permits noncoincident loads (220.62).

The rotary switch actually goes to 80A (position D). I've attached the installation manual for the US/JP version, see page 21.

You cannot legally attach a NEMA 14-50 to a 100A circuit. It must be protected by a 50A circuit breaker.

Daisy chaining Wall Connectors is going to be amazing for the Destination Charging program ... Why have 1 EVSE on a 100 amp breaker when you can have four?
