""" GI wire is the most common material for wire from building mains to earth. Earthing is done by a copper plate buried deep underground at a level where it remains in contact with groundwater beneath. A thick GI wire from this plate comes up through a pipe, and goes to the main panel. This serves as earthing for the whole building. A pit is usually made at the point where the pipe comes above ground, and provision is made to water it when necessary. The pit actually goes rather deep in the earth, and is filled with salt and coal mix. From this point, GI wires usually run through whole building for earthing. From floor mains, green PVC copper wire goes out to all earthing sockets.
