	The specifications will be those applicable to the country of installation: British Standard 7671, Indian Standard 3043, etc., etc. __________________ "Did you get my e-mail?" - "The biggest problem in communication is the illusion that it has taken place" - George Bernard Shaw, 1856

	i) The earthing specifications to be followed depends upon the Local Codes. ii) There are precise formulae available in the Standards (IS 3043, etc.) to calculate the theoratical value of earth resistance for a given type & size of earthe electrode.
