EV Charging - Can two cars plug in? (Photo)

Can two cars plug into this outlet (one on top and one on bottom, assuming both bring their own charging cables)? Or would that be unsafe?

Personal/logical deduction is that it should be fine to use both.

Kitchen outlets, for example often have separate circuits for each plug. Worst case, fuse should trip.

It looks like a 20A plug (based on the T shape left side of the outlet) - so it would really depend on the EVSE's that are being used. Most 120V EVSE's are 12A, so two of those (24A) would likely trip the breaker. Two 10A might be OK, but still a risk of tripping the breaker.

They're probably on the same circuit, so could trip the breaker with both charging at full 12A. But you couldn't plug 2 right angle cables anyhow, without a straight plug adapter.
Now, since they provided 2 plugs, they should be on 2 circuits, otherwise that's an installation destined to fail. If only one is allowed, then they should only have one plug.
Where is this? Looks commercial.
If the women don't find you handsome, they should at least find you handy.

The fact that there's two plugs means nothing besides the fact that it's a standard plug configuration. If you plug two space heaters in a standard outlet in your house, you'll blow the breaker on those too. So what matters is how it's wired, and none of that is obvious from the pic. But as previously mentioned, worst case scenario is the breaker blows and you go out the next morning to find your cars aren't charged (assuming you don't notice the breaker had flipped).

Sounds kinky.

Next question: Can one EV plug to two 15A outlets on separate circuits for faster charging? ;)

No. How would you connect the EV charger cable on 2 outlets of 15amps ?

Zooming in it looks to be a GFCI. Therefore, not likely to be split (I've never seen a split GFCI anyways). Best case, 20A as suggested, which appears possible as it is a "T" plug.

Thanks all, won’t take a chance and won’t plug in.

To answer the poster above, this is a commercial building. Surprised it’s not more clear (single outlet, or signage indicating to only use one outlet).

Get Elon to build you one with 2 outlets. (yes, L2 would make more sense, but clearly there are still those buying EV's without L2 charging)

Further the labelling. 4MPNA-41. That would suggest a panel identifier of 4MPNA, breaker 41. Generally if it's a split you would see "41-43"

Everything's possible.

If someone plug another EV in and blown the breaker, everyone loses right?

I wonder what's the original purpose of this plug is and where does the current wire goes to? That's a 2.4kw charge at best. So slow.

It is actually possible - your typical residential house is a 3 wire system, two 120V hots, and a neutral. You get 240V by using the two 120V hots at the same time.

If you have two separate 120V circuits which are connected on the breaker panel to the two different hots, you can create a cable that takes the 120V hot from circuit A and the 120V hot from circuit B and provides a new circuit with 240V. It's essentially doing the same thing as you'd do with a 2 pole breaker in your panel in a janky way.
Example:

Note: I wouldn't recommend it.
