I’ve watched that video, what research and sources? He doesn’t talk about any specs or provide them, doesn’t talk about patents or provide them. Can you link to his sources if you know where they are?

It’s strange how he’s being treated as the end source, while not having any sources at all.

Look up NEMA specs and patents, it’s not my job to educate people who are taking someone’s word without sources or anything. His experiments are flawed his receptacles are all from the last 2 decades.

“Go try it yourself and you’ll see”… sure I’ll use a plug from the era that these are from, that’s who these are for, not for people with modern plugs who would be ones watching a video and trying this.

Here a plug that utilizes the holes to make a secure connection that can only be removed by pulling on the collar to remove the pins that go through the holes.

Yeah it’s a thing and if you have the holes in the plug, they must meet NEMA spec since it actually is used for locking in lots of cases. Despite technology connections missing the patent and specs from their videos.

What sources did tech connections have other than their wrong and biased experiment on modern receptacles that wouldn’t have this feature?
