How can we make earth connection to electrical appliances??
Answer:
No. You have to bury a G . I Pipe of about 25 mm dia and minimum one meter length and flatened front end in the real ground .You can put char coal and salt in its side to make it always wet. On the top of the pipe make a cross hole of 8 mm dia and fix brass bolt in it. Take a copper wire of minimum 16 G and connect it to your appliance. If you check up the earth and neutral terminal it should not develop more than 5 volt. No use of putting in a bucket of sand.
No, it has to be earthed to something that is actually in the ground. Water pipes are comonly used, if they are metal, and run underground. Otherwise, a grounding rod driven into the ground outside and a wire running to it. You usually have them near your electric meter.
No, the "ground" connection must be to a metal rod or pipe that actually goes into the ground, not just a pail of dirt. The ground connection is the third, uninsulated wire in a standard electrical circuit, although in the U.S. and Canada, it is at the same voltage as the "neutral" wire - the white one, usually. If you go to the circuit breaker or fuse box and take the cover off, you will see that the third wires are all twisted together and connected to a cable that is attached to the cold water pipe coming into your house through the ground.
I'm not an expert concerning electrical matters, but I'm pretty sure that you would need more material to provide a useful ground. It also helps if it is something conductive (metal). The most common thing to use are metal pipes in your home (you have to make sure there are no plastic pipes between the connection and where the pipes go into the ground. The next thing I can think of for such a purpose would be a car (of course then you couldn't really drive it). It depends on why you need to make the connection. Most appliances will run without a ground, it is just less safe.
If the appliance comes with a 2-wire cord (i.e., a two pin plug), there is no need to worry about a safety ground. If it comes with a 3-wilre cord, then the plug should be attached to an outlet that has a safety ground pin. If it does not, adapters are available to provide one. It is not ordinarily necessary to install a safety ground connection on an appliance that does not come with one, but I once dealt with a refrigerator which had developed a bit of an electrical leak, so I installed a three wire power cord and thus fixed the problem.
The earth is used as a direct link to the power company so no you can't.
