for high-impedance grounded neutral systems grounding

connection requirements. (c) Grounding Electrode. The grounding electrode shall be as near as practicable to and preferably in the same area as the grounding conductor connection to the system. The grounding electrode shall be (1) the nearest available effectively grounded structural metal member of the structure; or (2) the nearest available effectively grounded metal water pipe; or (3) other electrodes as specified in Sections 250-81 and 250-83 where electrodes specified by (1) or (2) above are not available. (d) Grounding Methods. In all other respects, grounding methods shall comply with requirements prescribed in other parts of this Code. 70-114 NATIONAL ELECTRICAL CODE 250-27.
