Ground Rod Placement Suggestions

NEC 250.52(A)(5), which deals with rods and pipe electrodes states:
Rod and Pipe Electrodes. Rod and pipe electrodes shall not be less than 2.5 m (8 ft.) in length and shall consist of the following materials.

"The introduction to 250.52 deals with the length of the electrode. It very clearly states that the electrode shall be no less than 8 feet in length. There are ground rods manufactured and commercially available that do not meet the minimum 8-foot requirement, although the manufacturer may claim the rod to be 8 feet nominal in length." - cite:

"In other areas of the country, it is not uncommon to see ground rods being installed and passing inspection that are less than the required inch minimum in diameter. They are also produced with less than the listed requirement of 10 mils minimum of protective copper coating. While local codes do vary, the NEC is very explicit in the definition of a code-compliant ground rod electrode." cite:
