The ground pin or earth pin is the uppermost pin on your plug. It's purpose is to provide a safety barrier between you and the supply in the event of an overload or in case of an accident.
German appliances don't have three pinned plugs. The standards are the "Schoko" plug, which is a two pin plug with contacts on the side as a ground connection and the "Euro plug which is a two pin plug without a ground connection. There are adapters available at most good electrical stores.
The length of the ground prong is simply a matter of design for a plug application. Not all ground connectors are longer, the design of the ground terminal is simply to avoid improper wiring of the device.
orange is ground, power is red/white Ground is Plug 3, Pin 8 Keyed Power is Plug 3 Pin 4 Battery Power is Plug 3 pin 7
it is the brown wire in a three pin plug
No, the pin configuration would not allow this to happen.
It is to prevent electrical shocks.
The ground blade is the longest in a three blade plug.
Pin 1 = ground, Pin 2 = hot/plus, Pin 3 = cold/minus
Center pin is 12 V, outside is ground.
You don't, in theory, because the ground wire is missing. But if you must, cut the end of and add the new three pin plug, the two flat pins are for the two wires, the round is for the ground that is missing. If something has only two wires,say a light fixture, adding a plug that has the three is useless because the ground wire is missing, so it does not become safer just because you added it. If the end is bad,then you get a plug end that comes apart and is made for adding to a wire, do not cut wire,add another plug end by splicing it together with electric tape.
pin having largest area of cross section will be ground pin as it will hve lower resistance , hence provide lower impedence path for ground fault currents.
In North America the neutral pin is used to complete the circuit. One pin is "hot", one pin is neutral and the last pin is ground.
