    They are a byproduct of the manufacturing process. There’s a Technology Connections video about it that I’m too lazy to lookup on my phone.

      Technology connections got it wrong. The oldest receptacle he used was from the 2000s. He also didn’t do any research. Modern manufactures keep doing it for the all the old receptacles out there. It’s why the hole size IS specified by NEMA if you are going to include them.

      Theres plenty of patents that specify the locking function, and even some modern patents refer to those old locking features with their features.

        You’re a hero. I even remember watching this video a few weeks ago but I still can’t remember what he taught us the holes are for.
