An electrical Residual Current Circuit Breaker (RCCB) is a safety device that is used to protect people and property from electrical shock and electrical fires caused by ground faults.
A ground fault occurs when electricity flows through an unintended path, such as through a person's body or through a damaged electrical appliance. This can happen if there is a fault in the electrical system or if someone accidentally touches a live wire.
An RCCB works by constantly monitoring the electrical current flowing through a circuit. If the current flowing in the "live" wire differs from the current flowing in the "neutral" wire by a certain amount, the RCCB will detect the fault and immediately cut off the electrical supply to the circuit. This helps prevent electrical shock and fire hazards.
In summary, the purpose of an RCCB is to protect people and property from the hazards of electrical shock and fire caused by ground faults. It is an important safety device that is commonly used in residential and commercial electrical systems.
