For the record...
I've seen floor sanders stick bare, naked, stranded #8 into dryer receptacles to power up their Hummels. (belt style floor sander - Germany)
I had to ask:"Since the 30A 240VAC circuit is used time and again, why aren't you just using a dryer pigtail to Hubbel twist lock pigtail?"
At the most, only two styles would be needed.
...
For your amusement: bowling lanes -- the wood ones -- are sanded by 8 to 15 hp machines. The crews typically clip right on to the 200A 208Y120 bussing -- with battery style jumper clips! That's the NORM for them.
Don't ask how I know.
