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’s a plug, not a socket. By inserting the two shorted pins (white wire) into any socket, you would essentially short the live and neutral connectors of the socket.

      Oooh, yeah. Makes sense. Sorry, I had a brain fart. Of course it would short the outlet. Would definitely trip a breaker. Was thinking of an outlet for some reason.

      Correct, so you’d trip a breaker. You wouldn’t however electrocute yourself.

        If the neutral wire is faulty, the live wire is still connected to the ground wire and subsequently to the casing of the device. Thus, if somebody would touch the casing, the current (maximum what the breaker permits without opening) would flow through that person.
