Earth wire and Neutral wire are swapped. Can appliance work?

[Betadine]

Homework Statement

If we connect the neutral and Earth wires wrongly in the plug, can the appliance still work?

Homework Equations

The Attempt at a Solution

I am not too sure, but my answer is probably no. The circuit cannot be completed, as the current will flow to the ground, rather than back to the mains supply. Is that right?

Thank you :)

Yes it can . I personally experienced it. My one hand was holding onto a tap while I was drinking water from it and the other was holding onto the stainless steel washing basin next to it. I noticed that my vision was switching on and off at a high rate. Then I noticed my vision returned to normal as the vacuum cleaner in the house stopped and the phenomena started again when it the vacuum cleaner started up again. Upon investigation I discovered that that was the problem. Someone rewired it incorrectly.

In many countries the neutral is connected to Earth somewhere in the system so yes they may work.

You may have problems with Earth leakage detectors (Residual Current Detectors, RCD) tripping because they check that the live and neutral currents are similar (within 30mA). Any difference implies a leak to Earth and they disconnect.

It's not recommended to miss-wire a plug!

Some transmission systems have no neutral 'wire' from the generator. http://en.wikipedia.org/wiki/Electric_power_transmission#Single_wire_earth_return. The neutral side is connected to the substation through Earth. So in principle the neutral line in your house is at ground voltage. However, resistance in the return to the substation means that there may be some residual voltage. In multiphase distribution, successive houses get different phases. This helps to even out the variations in voltage on the neutral.

Yes, you are correct. Swapping the Earth and Neutral wires can cause the circuit to be incomplete, as the current will not flow back to the mains supply. This can result in the appliance not working properly or not working at all. In addition, it can also pose a safety hazard as the Earth wire is designed to provide a path for electrical faults, and without it being connected properly, the appliance may not be properly grounded. It is important to always connect the Earth and Neutral wires correctly to ensure the safe and proper functioning of electrical appliances.
