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.

    If it would be done exactly like in the picture nothing would happen, as the only wire going in is the ground wire.

        I just looked at the picture and the only line that goes to the plug is the grounding wire.

          Your comment is nearly identical to one made by someone in the linked post, and I’m pretty sure you’re trolling at this point.

          I won’t be engaging any further with you.

      In case you had the same brainfart as me, it’s a plug, not an outlet, so there could be no wires coming out of it and you could still short-circuit the outlet you plug it into…

        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 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.

            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.
