Ideally the plug end would be a 20a plug (one blade horizontal), but often in commercial/industrial places you'll find 15a outlets on 20a circuits. If used correctly this would be ok.
They're probably made for all the people renting floorsanders from Home Depot with no way to plug em in.
The scariest adaptors are the ones that dump or fake a ground - and 'cheaters' should be illegal

- lavezza 6y agoThe NEMA 'L' receptacles (L5, L6, ...) are locking. When you connect the two ends together you rotate them slightly so they won't disconnect due to vibration, etc.
- baking 6y agoThe circular one is a twist-loc that prevents it from disconnecting accidentally. The -|| 20A design is great in theory, but you only want to install a receptacle of that type if it is the only one on the circuit (and I mean only receptacle, so not even a single duplex) because what would be the point if you can plug in two devices that both require 20A. I've put these next to a window to power an air conditioner. The problem with the twist-loc is that the 15A and 20A designs are not compatible. You can't plug a 15A device into a 20A outlet, but 15A twist-loc receptacles are rare. So it is not uncommon to put a 20A plug on a device that draws much less than 15A if say you don't want someone to unplug your router by accident.
