Description
Earth rod.
Copper coated,offer installers the most economical method of achieving a low earth resistance.
It is made by 99.9% pure electrolytic copper on to a low carbon steel core.The threads are formed by a cold rolling process which ensures strength and maintains the molecularity bonded copper covering along the full length of the threads.
How deep should it go?
The rods need to be driven at least 6” below ground level, ideally capped with an earthing pit assembly.
How long should it be ?
Typical sizes are 9.5 x 1200mm (fixed) and 12.7 x 1200mm (extendable) using a coupling and driving head.
A very effective method of obtaining a low-resistance earth connection is to bury a conductor in the form of a closed loop in the soil at the bottom of the excavation for building foundations.
What is the purpose of earth rod?
The only purpose of a ground rod or a group of ground rods forming a ground field is to have a designed electrical path to dissipate a static discharge voltage (which can be lightning or other forms of static electricity) to the earth. The electrical earth ground rod is usually considered at zero volts.
Earthing is an important part of Lightning Protection, you can learn the basics of Earthing and Lightning.
