This is too thin for level 2 charging. My Tesla charger runs 6/3 and even then I cap charging at 32A, even though everything is rated at 50A. When in doubt, go heavier and under utilize it. Bad things are less likely to happen going that path rather than the opposite. And in most cases, the cost differences aren't that significant. Refer to:

That said, this 8/3 would be great for most dryers, convectional ovens, and small campers - devices rated ideally below 30A peak.
Most wires, including this one, is rated to 600V - which you aren't going to get off a typical breaker box. Continuous amperage is what you need to worry about and adjust your wiring size accordingly. Again, when in doubt, go one gauge higher.

55amps * .8 = 44 amps. 44 < 48 amps. You will also be on an 60 amp breaker. This is for copper. It's time to size up to 4awg.

Tell me about this all sorts of wrong though.

The conventional wisdom is to use copper wiring, an industrial grade socket (eg Hubbell or similar), and check the wiring of the socket yearly and re-torque to make sure the wire isn't backing out.

He was referring to an 60 amp charging rate which would require a 75 amp breaker and 4 AWG wire. But that is a very uncommon setup. I don't know of many chargers that charge at that rate. Most are 48 amps max. That's why I say you're more right.
30A dryer or water heater circuits will usually be 10 AWG, and 50A stove or EV charging stations will be 6 AWG.
8/3 is rated for 40 amps which is in no man's land - there aren't any 40A standard receptacles. Typically in a residential applications you would see 8 AWG circuits for like a 4 ton AC compressor, a cooktop or in-wall oven, or a hardwired EV charging station. Of those, only the in-wall oven actually needs the 3rd (neutral) wire so most would use 8/2. Probably why this is on sale.
Stoves / Ranges rarely have all of their 4 or 5 electric burners on 100% and oven on at 100% at the same time.
Second time I have asked and still waiting for a clear answer...
