Just who is recommending this and what is your application?

The motor exception is for when using the plug as the motor controller and applies to 1/3 HP and less motors
I’m betting it’s an EVSE application. There are all kinds of “experts” out there telling DIYers how to install these.

I think there is a misunderstanding between the customer and Tesla. The plug in Tesla charge cords can be connected to a maximum 50 amp breaker. If this is a wall charger it can get connected to a larger circuit (up to 100 amps) but the wall chargers are hard wired not plug in.

The NEC requires you to follow the manufacturers instructions. How ever "Perplexing" they may be,

Presuming the item is listed and instructions are a part of the listing.The NEC requires you to follow the manufacturers instructions. How ever "Perplexing" they may be,
Yeah and oddly the motor one goes away if the circuit supplies two or more receptacles, but the welder one stays 210.21(B)(3)

Don't listen to anything from Tesla. Not their car BS, and not any advice on wiring anything.
That's my honest advice.
Why does a Tesla need a 60A BC that terminates on a recept?
What's the issue with using a 50A BC ?

Does NEC say only follow the instructions if the item is Listed?
If a recept comes w/o instructions and w/o a Listing, but has on the plastic "50A 240V", when would NEC allow that item to be on a 60A BC? The AHJ should balk on that, no?

When it comes to what we are discussing here, a NEMA standards receptacle will very likely comply with both NEMA standards as well as any listing requirements.
Some other item may not.
Some instances a receptacle can be on a circuit with higher overcurrent protection device than rated amps of the receptacle, most common one is allowing 15 amp receptacles on 20 amp branch circuits. Many of us install those without even thinking about it as we have done it so many times. But the situations where you can't do that sneak up on you if you don't think about it.
