I’ve used similar devices many years ago. The issue then with them was there wasn’t enough tension, or bracing, holding the plug securely in place. The plugs slide around and fall out.
How many workshops have you seen with clean walls? That’s clearly not their intention. That is a residential wall. The back box will be non-standard so any electrician would loathe to use them. No ground either. It’s a nice idea, shit concept.
@Matt_Hale Yeah, if it’s designed to replace a standard receptacle (as opposed to a custom faceplate style), that’s a no go. Unless it’s being outfit into a house with only two wires, it’s against the NEC.
