Actually, the Neutral conductors are *NOT* connected to the plumbing system. The Neutral conductor is connected by the MEN link to the main earthing conductor, which is connected to the appropriate earth electrode. AS/NZS 3000 then requires that conductive pipe work be equipotentially bonded to the main earth conductor or earth terminal or bar (NOT to the neutral). David
