How actually current flows through earth wire if leakage happens?
Answers
Answer:The current flows from one point of the circuit, through ground, then back into the circuit. With only one connection to ground there is no circuit for the current to flow through. It can't flow to ground, because there is nowhere for it to flow.
Earthing is used to protect you from an electric shock. It does this by providing a path for a fault current to flow to earth. It also causes the protective device by using circuit-breaker in high voltage level and fuse in low voltage level to switch off the electric current to the circuit that has the fault or unbalance current.
Answer:
In any electrical installation, some current will flow through the protective ground conducter to ground.This is usually called leakage current.Leakage current most commonly flows in the insulation surrounding conductors and in the filters protection electronic equipment around the home or office
