It ensures 100% detection of leakage current& is available to sense the AC as well as DC leakage current. It is not preferable as it can only detect current that flow back through the main earth wire.A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by excess current from an overload or short circuit. Its basic function is to interrupt current flow after a fault is detected
