FAQ
An RCCB (Residual Current Circuit Breaker) is a device that detects and interrupts earth faults by measuring the difference between the live and neutral currents. If this difference exceeds a certain threshold, the RCCB trips, cutting off the electrical supply to prevent electric shock and reduce the risk of fire.
RCCB and RCD (Residual Current Device) are essentially the same and are used interchangeably. Both are designed to detect earth faults and disconnect the circuit to protect against electric shock and fire hazards. The term RCD is more commonly used in Europe, while RCCB is used in other regions.
