A Circuit Breaker RCD or Residual Current Device is an electrical safety device that is used to protect people from electrical shocks caused by faulty equipment or wiring. In simple terms, it is a switch that automatically turns off the power supply when it senses a current leakage to the earth.
- Why is Circuit Breaker RCD needed?
Electrical shocks can occur due to various reasons like a fault in electrical equipment, poor wiring, or human error. Such shocks can be lethal, especially in high voltage systems, which is why RCDs are installed to ensure the safety of people using the electrical system. It is mandatory to install RCD devices in homes, offices, and industrial setups by law to prevent accidents.
- How does a Circuit Breaker RCD work?
An RCD device works by constantly monitoring the current flowing through the circuit. It senses any current leakages that may be caused by damaged wires or equipment, which can result in electric shocks. As soon as a leakage is detected, the RCD shuts off the power supply within milliseconds to protect the user from shock.
- Types of Circuit Breaker RCD
There are two types of RCD devices – the RCCB and RCBO.
1. RCCB (Residual Current Circuit Breaker) - This type of RCD is used to protect the entire circuit from electrical shocks. It is installed in the main distribution board and is used to protect the entire electrical installation.
2. RCBO (Residual Current Circuit Breaker with Overload Protection) - This type of RCD combines the function of a circuit breaker and an RCD. It is used to protect individual circuits in a building and can detect both current leakage and overload conditions.
Benefits of Circuit Breaker RCD
1. Safety– The most significant benefit of RCD devices is that they enhance electrical safety. They reduce the risk of electric shock and other potential electrical hazards, thus protecting against injury or death.
2. Compliance – RCD devices are mandatory for homes, offices, and industrial sites. Installing them ensures compliance with legal requirements.
3. Reliability – RCDs are reliable and require low maintenance. They are unlikely to fail, ensuring the protection of the electrical system and the people that use it.
4. Versatility – RCD devices come in different sizes and types, which makes them versatile and suitable for different applications.
Conclusion
Circuit Breaker RCD is a crucial aspect of electrical safety. They protect against the risk of electric shock and other electrical hazards, which makes them a must-have in electrical installations. It is essential to invest in quality RCD devices to ensure that your electrical system is safe and reliable.
