There’s no ground pin, but there’s no hot wire.

    This is a plug. The big pins are live + neutral, which are shorted together and connected to the wire labeled ground (which heads to the exposed metal of whatever appliance is on the end of this cable).

    Yeah, this circuit would do a whole lot of nothing since the ground is the only wire entering the circuit.

    It would put phase directly on the metal casing of the appliance, if the circuit protection didn't work.

    Please avoid the temptation to comment on something you know nothing about, this is actually a serious safety concern if someone followed this diagram.

    Even worse. Orientation of pins like this is used in 240V circuit which means it has two antiphase live wires. This means that after shorting them, if one trips but not the other (if these two have independent breakers - idk if code requires otherwise) 120V is sent to device ground, and this one can be cut off by GFCI if used, but i hear it's uncommon

    If it was normal 120V circuit, breaker would cut off live and left neutral connected to device ground, which still can be some 20V depending on conditions
