    Trying to get a sense of scale, the 4 screw points on the red retainer look like 1 1/4in.

    So are the prongs like the size of a thumb? 😳

      Maybe a pinky.

      But still, these are normally used for metal lathes and other big workshop machines like this.

        I’ve never noticed one but now aware, expect to start seeing them everywhere hiding in plain sight

        You don’t generally see them in the US until you get to Industrial/Datacenter level. Since the US tends to use NEMA standards, for example for a 220V dryer/EV charger we’ll use a NEMA 14-50 plug.
