![]() ![]() when the soil that was disturbed in the installation of the electrode does not make good contact with the electrode when backfilled.ground electrodes are on or close to bedrock,.ground electrodes are in shallow sandy soil that can become dry.Ground Enhancement Compounds are used to increase the efficiency of ground electrodes (lower the measured resistance / impedance) when the native soil they are in contact with has a high resistivity. Reference the Class I and Class II Lightning Conductors for complete description of Cables suitable for grounding Grounding cables must be UL96 listed and labelled for code compliance. Hot sale lightning earth rod clamp 5/8 16mm 20mm welding ground rod clamp. Lightning protection codes specify their use based upon the Class of system provided. Purchase high-selling lightning rod clamp on at affordable rates. Our 3/4 X 12 copperclad ground rods meet standards UL 467, ANSI C33.8 RUS, and are approved for use in lightning protection per UL 96 and UL. These may take the form of radial cables, grounding loops / counterpoise cables that surround the protected structure and interconnect other ground electrodes such as rods and plates. Opt 2 – Number of Bonding Plates ( 1) (2)Ĭopper / Tin Plated copper are also used as ground electrodes to provide energy dissipation and equipotential bonding at or below grade ( Aluminum cables may not be used in the ground ). Opt 1 – Material Copper (C) Stainless Steel (SS) Why does this happen with lightning During a lightning storm, there is an imbalance between the charge. If it does not have an easy route, it may strike anywhere and seeks out things that are tall to find the fastest route to the ground. and disperse the energy safely into the ground (grounding network). Lightning, or electricity, is searching for the quickest route to the ground. Where soil depth does not permit use of ground rods.ġ2” x 24” x 1/16” (305mm x 610mm x 1.59mm) Lightning rods (and the accompanying protection system) are designed to protect a. To be buried in soil using ground enhancing compound to provide high contact area between plate and native soil. Introduction This is a companion to the Rooftop Mounting Guide, where we discuss installing an antenna your roof. Provides 2 sq ft of contact area with soil. Meets requirements for LPS Codes in North America This is required only for some antennas- ones which require current flow to ground to complete the antenna circuit. See the TIS Page on Lightning Protection. ampacity) to discharge lightning and fault currents into the ground. Copper wire offers high fusing current (see section on fusing current vs. for many decades as the standard grounding conductor in substations, transmission, generation and distribution systems. Copper Ground Plate with Bonding Plate connector for grounding cable. The requirements for a ground for lightning protection are much more stringent than for a safety ground as a lot of energy must be safely dissipated. Copper wire and cable have been used in the U.S.
