The following amendments, additions, and/or deletions are made to Article 250 of the National Electrical Section 250.52(A)(1) Metal Underground Water Pipe. A metal underground water pipe in direct contact with the earth for 3.0 m (10 ft) or more (including any metal well casing bonded to the pipe) and electrically continuous (or made electrically continuous by bonding around insulating joints or insulating pipe) to the points of connection of the grounding electrode conductor and the bonding conductor(s) or jumper(s), if installed. Grounding electrode conductor shall be bonded to water pipe within 5 feet of where cold water pipe enters the structure. Section 250.52(A)(2) Metal In-ground Support Structure(s). One or more metal in-ground support structure(s) in direct contact with the earth vertically, with or without concrete encasement. If multiple metal in-ground support structures are present at a building or a structure, it shall be permissible to bond only one into the grounding electrode system. Informational Note: Metal in-ground support structures include, but are not limited to, pilings, casings, and other structural metal. Section 250.52(A)(3), "Concrete - Encased Electrode," is amended to read as follows: All new structures, both residential and commercial, require a concrete encased electrode to be used as the principal grounding electrode system.
