Don’t those plugs mean something though? Like a specific Amp/voltage level? Or can you use this anywhere? I’ve only used it for specific Amp/voltage required situations (UPSs actually).

They all mean something. For every straight blade there's generally an equivalent twist lock. https://en.wikipedia.org/wiki/NEMA_connector#/media/File:NEMA_simplified_pins.svg https://en.wikipedia.org/wiki/NEMA_connector#/media/File:NEM...

Yep, which is why I linked the one specifically for 20A 125/250V, IIRC that matches the OP's use case. Surprisingly, there is no physical shape (that I'm aware of) to distinguish between 120V and 240V, it's up to the user to be aware of possibility of alternate voltages. I have seen color schemes used to distinguish voltages.

  Orientation of the blades. The NEMA 2-15 for 240v 15a has both blades horizontal instead of vertical like a normal 120v 1-15 plug.

  You can get l6-30p inlets. Appears to be common for RV use.
