RCD Protection:


A Residual Current Device is a safety device that switches off the electricity automatically if there is a fault. RCDs are far more sensitive than circuit breakers and provide additional protection against electric shock.


Additional protection by means of an RCD can be a lifesaver. An RCD constantly monitors the electric current flowing along a circuit. If it detects electricity flowing down an unintended path, such as through a person who has touched a live part, it will switch off the circuit very quickly, reducing the risk of death or serious injury.


RCDs can help protect you from electric shock in areas like a bathroom where you may be wet, or become wet. It is also very important to have RCD protection when using electrical equipment outdoors. Fixed RCDs are installed in the consumer unit (fuse box) and can provide protection to individual or groups of circuits.


Remember, a circuit breaker is really there to protect the cable from damage through overheating. An RCD is there to protect human life and is known in the industry as a ‘People Protector’.
