![]() MCB (Miniature Circuit Breaker) – Construction, Working, Types and Applications. ![]() Upon touching the conductor or the equipment, the current can pass to the earth through the person’s body. It can also occur when the live conductor comes in contact with the body of the equipment (if the equipment is not properly grounded). It can occur due to damaged insulation of the live conductor or broken conductors. Therefore, protection devices are used to disconnect the power source when such current leakage is detected Causes of Earth Leakage?Įarth leakage can occur due to various reasons. The consequence of electrical shock may prove fatal if the leakage current exceeds the only 30mA. It may flow between their poor insulation or through a person’s body & cause electrical shock. ![]() The electrical current that flows from the live conductor to the earth through an unintended path is called earth leakage.
