Earthing procedure for home pdf

In small installation, use metallic rod (diameter = 25mm (1inch) and length = 2m (6ft) instead of earth plate for earthing system. The metallic pipe should be 2 meter below from the surface of ground. To maintain the moister condition, put 25mm (1inch) coal and lime mixture around the earth plate. Earthing is a process to discharge and transfer the charge into the earth through a very low resistive wire. We can find it in our surroundings as it requires for utilizing power for domestic purposes. Normally for domestic purposes, we use a single-phase ac supply, and an earthing for completion of the circuit through transferring of charge. 1.0 PURPOSE The purpose of generating this Method Statement is to define the procedure step by step to implement the correct practices for Installation of Earthing, bonding & Lightning protection system through the guidelines contained herein so as to ensure that the job execution complies with the requirements and serves the intended function to a satisfactory level. 2.0 SCOPE… PLATE EARTHING PROCEDURE - A plate made of either copper or galvanized iron with dimensions 600mm x 600mm x6.35mm is buried vertically in the earth, which is not less than 3m from the ground level. For successful completion of the procedure: 1) Install an earth pit. 2) Insert plate electrodes. 3) Make earthing and water connections. Any material of given dimensions would offer the same resistance to earth. Except the sizing and number of the earthing conductor or the protective conductor. Pipe Earthing Vs Plate Earthing. Suppose Copper Plate having of size 1.2m x 1.2m x 3.15mm thick. soil resistivity of 100 ohm-m, In the case of plate earth electrodes, a watering pipe of 20mm dia. medium class pipe must be provided and attached to the electrodes. In pipe electrodes, a 40mm x 20mm reducer shall be used for fixing the funnel with mesh. The watering funnel attachment shall be housed in a masonry enclosure of size not less than 30 cm x 30 cm x 30 cm. To ensure safety, earthing can be done by connecting the electrical appliance to earthing systems or electrodes placed near the soil or below the ground level. The electrode or earthing mat equipped with a flat iron riser is installed under the ground level. It helps to connect all the non-current-carrying metallic parts of the equipment. The earthing conductor is commonly called the earthing lead. It joins the installation earthing terminal to the earth electrode or to the earth terminal provided by the Electricity Supply Company. It is a vital link in the protective system, so care must be taken to see that its integrity will be preserved at all times. The Procedure of Chemical Earthing. The procedure for chemical earthing is very much similar to another type of earthing. There are some of the differences in it which are included in this article. At the first, a deep dig is dug which must be suitable for a good earthing and don't cause any damages to the person or animals if passes from This Method Statement describes the sequence of activities involved in the installation of Earthing, Bonding, and Lightning Protection as per the requirements derived from Scope of Work, Contract Specifications, Codes and Standards of the project. Example of electrical earthing /lightning protection implemented in the site project 1.0 PURPOSE The purpose of generating this Method Statement is to define the procedure step by step to implement the correct pra
