Earthing procedure for new residential home in India.

Hello Guest,

General:

Your electrician should be well aware of your local requirements.

If he is unaware of those, get a new electrician, because you as the home-owner should not have to advise the electrician.

Note: If you give advice to any Contractor, you effectively take responsibility for any mistakes, because you have made yourself the Main Contractor also the Clerk of Works in Contract Law.

The earthing requirements will vary dependent on soil resistivity, voltage and number of phases, plus the type of supply (MEN = Multiple Earthed Neutral), and more factors....

In extremely high soil resistivity, (hot dry desert sand, dry rock, gravel/shingle in dry area etc), an Earth Mat may be required plus all exposed bare metal in the installation bonded to that Earth Mat.

In medium or low soil resistivity, a hot-dipped galvanized substantial rod (20mm diameter or more) some 2 metres long, driven into the ground on the side of the house away from the Equator (so that the area does not fully dry out) may be sufficient.

Without further details of your local site situation, it is difficult to advise you further.

As I said earlier: Your electrician should know the local requirements, that is why you pay him to do the work.

Kind Regards....

Hi

Thanks for the reply. I agree with you on local soil conditions.

I was hoping someone from Bangalore may reply with a specific kit to buy.
