Greetings,
I posed my questions at the dealer and I called the Ariya help line and they lacked the info I needed. A few days ago we did a closed track test drive and it was a great experience. One of the tech experts showed me the 240 and 120 V cable that comes with the vehicle but I regretted not taking a photo of the plug end for 240 V input. I'll need to change the 240V outlet to match the plug end, but I need to see the plug first. Does anyone have any photos of the plug or have a link where I could see the plug? I'd rather not wait until the car is delivered in November to get what I think is a simple answer. And does anyone know if the two 30 Amp breakers are sufficient? Again the dealer and the Ariya help desk did not have the answers for me.

Welcome to the forum @Stevesall! What did you think of the Ariya on track? Maybe this video can help you out?

Here is the photo I took of the cable in the show room model at the Pamona Ride and Drive event. It was about 10 to 12 ft long.

Thanks anyway. I needed the photo of the end that will plug into a home 240VAC outlet. The blue plug to the extreme upper right looks like the one I need. On that blue plug, I can't tell if the two 120VAC leads (above the ground lead) are at a 45 deg angle (common). The dealer could not help me with my question nor could the Ariya help desk. I guess when I pick up my Ariya in November, I can look at the plug, drive to the hardware store, buy the outlet, install it and plug in my Ariya. Strange, nobody from Nissan can help me so I can get a jump on wiring the required outlet. It will remain a mystery until then. Does anyone see anything wrong with that?

Steve:

I believe that photo is all you need for what you asked. Sorta. He's showing you the head of a male Nema 14-50 plug. The white adapter looks like a 120v (known as a Nema 5-20R) to 14-50R adapter. It's to allow 120V use of the EVSE. The blue one looks like a 30 amp RV plug, although it's hard to know.

So yea, that's a plug capable of charging at up to 42 amps continuous.

Is a 30 amp breaker sufficient? There are at least 3 answers to that:

1) Usually, yes. That will deliver 5.76KW per hour. The Ariya does something like 2.7 miles per KW, so just over 15 miles of range per hour of charge (using NEC EV code). Most folks will not need more charging than that if home charging regularly. (Of course, where did you get the EVSE from?)

2) It's hard to know. You may not safely, or within code, plug in an EVSE with a pilot signal greater than the circuits capability. So what EVSE did the Ariya ship with?

3) No. To utilize the full rated capability of the OBC we would need a 40 amp rated circuit. (if it came with that large an EVSE). The more recent Leafs, (I believe) ship with exactly that: A 32 amp EVSE cable that requires a 40 amp circuit.

Bottom line: We'd need to know the factory supplied EVSE's (the cord) output to know that, not the plug type. The average NA home has a 15 amp 120V circuit. Which is why the older Leafs shipped with a 12 amp 120V EVSE. I believe now they ship with a 32amp 240 (which you could not even faintly use).

Personally I too have a 30 map available in my garage. It's all I'll likely need. I'll move that to a 14-50 plug (perfectly within code to do that) and look for a configurable EVSE. Something like this:

Amazon.com: Grizzl-E Level 2 EV Charger, 16/24/32/40 Amp, NEMA 14-50 Plug/06-50 Plug, 24 feet Premium Cable, Indoor/Outdoor Car Charging Station, Classic/Avalanche/Extreme (Classic 14-24-PB) : Automotive
or:
Amazon.com: Electrify America Electric Vehicle (EV) Charger, Level 2, WiFi Enabled, 16 to 40 Amp, 240V, UL Listed, Energy Star, Indoor/Outdoor, 24-Foot Cable, NEMA Plug, Remote Access, App Control : Automotive

I could set either to 24 amps and I'd be fine. Mind you if the Ariya ships with a 32a L2 charger it would be even cheaper to install a 50 amp circuit and be done w/it.

The previous post was excellent and needs nothing else but I figured it should be said again that no, you absolutely should not simply change your 30amp outlet to a 50amp outlet. The entire circuit including the wiring, receptacle and breaker needs upgraded.

The US spec Ariya is 7.2kw w/ 32amp EVSE so with derate you need a minimum 40a circuit.

Love you brother, but that's incorrect. Mind you your spirit and intent are on point, but to be pedantic: Code requires you not exceed 80% of the entire circuit capability for continuous use. Which I believe is three hours (but check me on that, it might be 2 or 4 also). It's perfectly acceptable and utterly within code to use any larger sized outlet, or oversized wire for that matter. You may never install a larger breaker than the entire circuit can support. Yes, I appreciate some putz could then plug in an oversize EVSE. But keep reading.

In fact, there are plenty of stories of folks melting outlets when used at upper amps. Too many cheap imported outlets IMHO. Using a 14-50 at upper amps of a 30 amp circuit does lots of things, eg more heat head room, but most commonly it allows users to standardize their equipment. EG: We now have 3 families floating around owning PHEV/EV's and we all can plug our EVSE's into each other's homes. YMMV, but personally I label my outlet to say "24 amps maximum", and of course it's not like strangers are pulling into my garage to charge up, so I know who might be pulling more.

The bottom line on the NEC code is this: It is the operator/owner of the circuit's responsibility to manage the current draw of devices being attached. Never the plug, wire, or circuit breaker. There are lots of reasons for this. I'll give you a few:

1. Let's take a 100 amp EV subpanel in a garage with 4 different 14-50 outlets distributed throughout.
   1. What's to stop the combined load from exceeding the 80 amps allowed to the main panel?
      1. Nothing. Circuit owner/manager only, or you over-heat the circuit and hope the breaker goes first.
      2. Could he run all 4 at the same time?
         1. Or course. But not at full capacity.
      3. As you may have noticed it gets much more complicated when you become a multi-EV family. Code recognized this when it was developed.
2. Take a 120v 15 amp circuit in a garage. Those are never dedicated to one plug. Any OEM 120V EVSE plugged in will draw 12 amps, and if so much as a garage light is turned on you've exceeded code.
   1. What's to stop that?
      1. Nothing. Circuit owner/manager only, or you over-heat the circuit and hope the breaker goes first.
3. While a 60 amp EVSE is supposed to be hardwired, nothing stops someone from putting 14-50 on one. Heck I'm going to until I get my new circuit is installed.
   1. What if I don't turn down my OBC to 24 amps?
4. What's to stop somebody from setting their EVSE/OBC to 30 amps on a 14-30 connector? Certainly outside of code, right? But the connectors fit.

As it's written today, and short of intelligent EV load panels, I don't see anything changing. Code drops responsibility for load management on the circuit owner/manager. In fact, strictly speaking access to EV breakers are to be restricted from casual access. EG: I have the EV subpanel at my son's house documented, labeled, metered, and locked. As placarded & documented only he and I are to have access to enabling outlets. This to mitigate liability.

luck to you,
