EARTH RODS & ACCESSORIES
Type
• Earth rods:
ERB series
• Accessories
- Threaded couplings: ERBO series
-Threaded driving heads: ERBD series
Use
A well designed earthing system is essential to ensure protection of personnel and equipment from danger associated with fault currents or lightning within buildings or areas falling within their ‘zone of protection’.
Features & Benefits
• Wallis copperbond earth rods offer installers the most economical method of achieving a low earth resistance.
• Each rod has a high tensile strength, low carbon steel core. 99.95% pure copper is applied electrolytically and forms a metallurgical bond between the steel core and the copper. This combination makes the rod ideal for deep driving whilst also provides lasting resistance to corrosion.
• The threads are formed by a cold rolling process which ensures strength and maintains the molecularly bonded copper covering along the full length of the threads. Cold-rolled threads are stronger than cut-threads.
• The standard copper thickness is 0.25mm. Greater copper thicknesses are also available. Please contact our sales office for further information.
• These Wallis high-strength couplings are used for joining copperbond threaded earth rods together. They facilitate deep driving and ensure continual contact between the rods both during and after installation.
• The coupling also protects the earth rod threads during installation with the threaded driving head. There is a lead-in for ease of assembly and the hexagonal design allows for grip and keeping the coupling tight when driving into the ground. All Wallis couplings are manufactured from a high copper content alloy ensuring excellent corrosion resistance.
• These Wallis re-usable threaded driving heads are suitable for driving copperbond threaded earth rods by hand or with a power hammer. The driving head screws into the threaded coupling to allow deep driving of the earth rods.

Use
A well designed earthing system is essential to ensure protection of personnel and equipment from danger associated with fault currents or lightning within buildings or areas falling within their ‘zone of protection’.
Features & Benefits
• These earth rods are designed for use where extremely high corrosion resistance and exceptionally long life are required. Solid copper earth rods are produced from solid copper bar and are internally threaded for jointing. When deep driving a solid copper earth rod the usual practice is to insert the rod into a bore hole and backfill with either Low-Resistance Earthing Compound or Bentonite, (see page 44 for further details).
• The driving head protects the internal thread and the top of the solid copper earth rod from damage when being driven into the ground.
• These driving spikes enable solid copper earth rods to be driven easily into the ground.
• The phosphor bronze coupling dowel is used for joining solid copper earth rods together.
