NEVER USE A GROUND ROD AGAIN!!!
NATIONAL ELECTRICAL CODE - NEC2008
ARTICLE 250 - GROUNDING AND BONDING
PAGE 70 - 105
"...(5) Rod and Pipe Electrodes. Rod and pipe electrode shall not be less than 2.44 m (8 ft) in length and shall consist of the following materials.
(a) Grounding electrodes of pipe or conduit shall not be smaller than metric designator 21 (trade size 1/4) and, where of steel, shall have the outer surface galvanized or otherwise metal-coated for corrosion protection.
(b) Grounding electrodes of stainless steel and copper or zinc coated steel shall be at least 15.87 mm (5/8 in.) in diameter, unless listed and not less than 12.70 mm (1/2 in.) in diameter
(6) Other Listed Electrodes. Other listed grounding electrodes shall be permitted.
(7) Plate Electrodes. Each plate electrode shall expose not less than 0.186 m2 (2 ft2) of surface to exterior soil. Electrodes of iron or steel plates shall be at least 1.5 mm (0.06 in.) in thickness..."
The Saf-T-Electro Plate replaces the 8’ x ⅝” ground rod and can be manually installed using a T-handle, ratchet or an impact wrench.
The installation tool is available in 1’ increments - 1’, 2’, 3’ and 4’ lengths for installations at the required depth.
The area surface of an 8’ x ⅝” ground rod is 165 square inches.
The area surface of the 4’ x ¼” Saf-T-Electro Plate is 185 square inches.
The Saf-T-Electro Plate is available in metal plate steel and stainless steel.
The Saf-T-Electro Plate is screwed into the ground with a wedging effect, whereby maintaining tighter contact with the soil. During installation of a regular ground rod, the hole is made bigger by pounding the rod into the soil reducing the amount of contact with the soil, thus providing less conductivity.
Therefore, the Saf-T-Electro Plate obtains better grounding than a ground rod.
