It lists basic standard receptacles 15A to 60A like those found in a basic NEMA chart. 5-15 and 5-20 are listed.
For other types it says:
Devices of configurations other than those indicated in the table have horsepower ratings only if such ratings are marked on the device.
Now you made me look at the link and I see some common configurations that I see a lot that are not in compliance with the rating. Big one that stands out to me is NEMA 10-50. They have been used for decades on the farms here and is not uncommon at all to see them supplying 10 HP single phase motors. Bad enough that they should probably be using 6-50 before even considering HP rating.
Farmer puts up a new grain bin, he wants one to plug in his portable auger that he uses on several other sites, so what do you do, especially when there has been little or no serious mishaps with those over all those years?
It gets even more complicated when I believe the 2017 NEC will require GFCI protection on such receptacle outlets.
Install something that is NEC compliant and you know they will just make a cheater adapter anyway because they are going to still use it at existing sites.
