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.

    You may be doing what I initially did and mentally treating it as an outlet. The live prong on the displayed plug would be inserted into an real live outlet thus energizing both the neutral and ground. The dead short should quickly trip the breaker but maybe not before the outlet or plug is nice and crispified.
