Even when an oven is turned on for hours, it's not running flat out for hours. The elements cycle on and off

A heavy duty receptacle can certainly tolerate more insertion cycles. But they also have higher insertion force and larger contact area that translates into lower contact resistance and therefore less heat.

It seems to make sense to spend the bucks for an EV rated receptacle if you are starting from scratch, and not hardwiring the charger. The Hubbell/Bryant made in the USA is about $50.
I found some cheap Chinese receptacles when I was looking. Sorry, but I am not risking my property to a cheap Chinese receptacle. I know the big electrical brands have stuff made in China now, but at least Hubbell, Leviton, Legrand, and the other big brands have good quality control and are going to be UL listed for real. There are certainly Chinese manufacturers who have no issue with putting the UL logo on something that was never tested by the UL.

UL doesn't actually test for the number of insertions on the receptacle FWIW.
It's a pretty big gap in testing IMO.

an electric oven is a flawed comparison to an EV charger. the oven heating elements cycle on and off and are NOT considered a continuous load since they are not anticipated to run for more than 3hrs. an EV on the other hand is....

My point is the Chinese manufacturers likely never actually submitted their receptacle for UL testing, but in some cases they simply put the UL label on the receptacle anyhow.
Gotcha. I thought you were talking about the cheap Levitons.
You'd have to be pretty crazy to buy a ENERLITES 14-50 for $9.99 from Amazon.

I used the Hubbell based on my research....
Take a look at the photos of the different receptacle brands in the first post on this thread.
They photographed all the angles, but this really caught my eye:

That $9.99 Chinese receptacle from Amazon is the type of receptacle I was talking about, and would never use. For non-EV purposes a Legrand receptacle from Menards isn't that much more, and a Leviton is a few bucks more at HD.

The Leviton is pictured above. Post 48 on the left.

I not sure what to conclude from that picI used the Hubbell based on my research....

Leviton now has their own equivalent EV rated 14-50R device and labeled as "Heavy Duty" with the eCar symbol.
The differences between HD and the standard version are:
- higher torque requirements (75 vs. 40 in-lbs) set-screws vs. screws
- Copper only connections permitted
- Larger contact surfaces (hence the depth)
- Nylon housing (for slightly higher heat resistance, better UV protection, different flame rating)
