EARTHING CONDUCTOR Sample Clauses
The EARTHING CONDUCTOR clause defines the requirements and standards for the installation and maintenance of the electrical earthing conductor within a project or facility. It typically specifies the type, size, and material of the conductor, as well as the methods for connecting it to the earth and to other components of the electrical system. This clause ensures that all electrical installations are safely grounded, thereby protecting people and equipment from electrical faults and reducing the risk of electric shock or fire.
EARTHING CONDUCTOR. (i) The earthing conductor (protective conductor from earth electrode upto the main earthing terminal/earth bus, as the case may be) shall be of the same material as the electrode, viz, GI or copper, and in the form of wire or strip as specified.
(ii) The size of earthing conductor shall be specified, but this shall not be less than the following (For calculating the size of the earthing conductor in design).
(a) 5mm dia (6SWG) for GI, or 4mm dia (8SWG) for copper wire.
(b) 25mmx4mm in the case of GI strip, or
(c) 20mmx3mm in the case of copper strip.
(iii) Earthing conductor larger that the following sectional areas need not be used, unless otherwise specified.
(a) 150 ▇▇.▇▇. in case of GI in case of GI, or,
(b) 100 ▇▇.▇▇. in the case of copper strip.
EARTHING CONDUCTOR. Earth continuity conductor along with sub main wiring from Main/ Sub Distribution boards to various distribution boards shall be of copper. Earth continuity conductor connecting Main & Sub Distribution boards to earth electrode shall be with galvanized MS strip.
