i hope you will take this in the right spirit, after all, i am 66 years old, and can be forgiven for volunteering some unsolicited advice.

You have been asking questions which have caused CR4 experts to wonder whether there is any 'cultural' opposition to use Google or other search engines. See your thread http://cr4.globalspec.com/thread/67973/Improving-Earthing

It took an American to give you the link to an Indian Electricity Board website. In a country where Google employs thousands of people, and is available in all Indian languages (if you are not ok with English), this is not warranted is it?

Please do your searching on Google or Bing or elsewhere before you ask at CR4, is my humble request.... coal anticorrosive

You may not find what you are looking for. We are always there to help. However, only after you have done your own bit.

God bless.

Thanks, old man. You have 2 years on me.

This is Good Advice.
