Earthing installation methods

Earth lead should be the same metal as the earth electrode. If you are using different conducting metal then the result can be different than you expected. It should lay in such a way that it is always well preserved.

It can be taken through the conduit and connect with the system or equipment. But you have remembered the size of the conductor. The perfect size or an average earth lead conductor is a minimum of 3. If you have the authority to select one of these earth lead, I suggest you select Copper earth lead. Earth Continuing Conductor: It is the connecting wire which will connect the different types of electrical equipment bodies to the earth lead or the earth bus bar on the ground level.

Methods of Electrical Earthing Systems: Earthing system always depends on the types of an electrode that you are using.

November 20, If this is the first time for you then please read my previous post about Electric Earthing System. You will get August 21, If this is the first time for you then I will suggest you have a look at my previous post about Continuity tester. All materials received at site shall be inspected and ensured that the materials are as per approved material submittal.

Any discrepancies, damage etc. Material found not suitable for site use will be removed from site immediately. All materials and accessories should also be free of dust, scale, or oil.

Ensure the location of earth pits are coordinated with other external services like water supply pipe lines, drainage pipe lines, gas pipe lines, external lighting systems and other services.

T denotes that the star point of the source is solidly connected to earth, which is usually at a location very near to the winding. I denote that the star point and the winding are isolated from earth.

The star point is usually connected to an inductive impedance or resistance. Capacitive impedance is never used. The second letter denotes the consumer. The consuming equipment needs to be earthed.
