The copper bonded stainless steel rod (low carbon high tensile steel alloy)earth electrode shall conform to the standard BS 4360 grade 43A or EN 10025:2-004 S275 IR molecularly bonded by 99.99% pure high copper coating thickness 250 micron or more. The earth rod shall have following:
a- The min. length of earth electrode shall be 3.0 meters long. The length of electrode may be increased in multiple of 1.0 meter to reduce earth resistance. b- To increase the length, pieces of similar rod shall be either exothermally welded to basic socket of suitable size. These sockets shall be molecularly bonded by 99.99% pure high conductivity copper on inner & outer surface with copper coating thickness 250 micron or more.

All of these power sources provide a route by which the damaging power of lightning can travel. Most of the damage caused by lightning strikes affect electrical and electronic components, via induced over voltages on the lines entering the building. Metallic pipes (water, gas, etc.) can also introduce surges, while the lack of equipotentiality between the various services or between the various earth connections, can cause issues when the electric earth and the so-called clea co puti g earth are separated. The installation of Type 1 + 2 surge arresters can protect incoming power lines and sensitive circuits when lightning strikes, due to their low residual overvoltage, however the earthing of the metal pipes that go into the building will be necessary in order to create an equipotential system. Type 2 surge arresters are also required for the protection of computer systems, inverters and sensitive equipment. These surge arresters must be installed in the various electrical cabinets present on site. Recent standards indicate tvhat a conductor beyond 10 m in length, is no longer protected by a single surge arrester.
