Check the comments of the original post for the stupidity.

For those of you without an electrical background, the diagram shows the protective earth connected directly to phase, with phase and neutral also joined.

Correctly wired, this would be a three pin plug, with the earth wire connected to the earth pin in the plug, with the other end connected to the metal casing of the appliance. This is a critical safety feature, which will cause the circuit protection to trip in the event a phase wire contacts the metal of whatever this is connected to.

If this was actually done, the most likely outcome is it would trip a circuit breaker, but if the neutral was broken, it would connect phase directly to the casing, and likely electrocute someone.

    It also looks like plug neutral is connected to plug live too? So its one single node to ground on the plug side?

    are we sure the prompt was not “how to create a plug in north America for maximum damage?” 😄

      Nah, maximum damage would be phase to earth alone, at least in terms of human safety.

      This is a great way to wreck a socket though.

        It’s a plug, not an outlet

        Current source is from the prongs.

        It’s just so bad it trips you up. Also, in North America it’s fairly rare to wire a plug; much more common to wire up an outlet. In EU, didn’t many appliances ship without a wire and you were expected to install your own? Is that still a thing?
