The document discusses key considerations for implementing electric vehicles including public charging stations, connectors, and safety protocols. It emphasizes the importance of surge protection for electric vehicle charging systems and equipment, as lightning strikes and surges can damage systems without proper protection. The document provides guidelines for proper earthing and grounding designs using copper-bonded rods to reduce earth resistance and protect equipment from surges and lightning. It calls for following electrical safety standards and installing surge protection devices to safeguard equipment and human lives.

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.
