What will happen if the ground wire and neutral wire shorted?

On a normal circuit, nothing should happen that you can see or be aware of.

On a GFI protected circuit, the GFI will trip.

This condition, when known, needs to be corrected, as the neutral is current carrying, and a neutral ground short will send current through the grounding system. Arcing can happen at loose connections of the grounding system, even thou there should be no loose connections, it still happens.

Hi, if ground wire and neutral wire shorted nothing will happen. Neutral wire is actually a ground from the electric substation. Ground wire in your house is used as a replacement for neutral wire in case of it's breaking, to provide grounding in order to prevent your home appliances from burning out. So, if you connect ground and ground nothing will happen.

In North America, this statement is NOT TRUE:


Ground wire in your house is used as a replacement for neutral wire in case of it's breaking, to provide grounding in order to prevent your home appliances from burning out. .

A neutral is a grounded return for the circuit, and is to be kept separate from equipment grounding in circuitry.

An equipment ground, green, bare, or green with yellow stripes, is only to ground the metal raceway and metal housing of an appliance.

There is a continuety between the Neutral and Ground of the DG in my factory(in both input and Output side). Is there any problem because of that? If so what type of preventive measures should I take?

There will be continuity between neutral and ground, as they are joined at the mains service disconnect.
