RCD’s designed for high level of protection from Electrical shock hazards.

 

How does RCD work?

A Residual Current Device (RCD), also known as a Ground Fault Circuit Interrupter (GFCI), is a crucial safety device used to protect against electrical shock hazards. Its primary function is to rapidly interrupt the flow of electric current when an imbalance is detected between the energized and neutral conductors in an electrical circuit.

The RCD constantly monitors the current flowing through the circuit and compares it to the returning current in the neutral conductor. Under normal conditions, these currents are balanced, indicating that the electrical system is operating safely. However, if there is a leakage of current, such as when a person accidentally comes into contact with an energized part or a fault occurs in the wiring, an imbalance is created.

When the RCD senses this imbalance, it reacts instantaneously, quickly disconnecting the power supply and breaking the circuit. By swiftly interrupting the current flow, the RCD helps prevent electric shocks and significantly reduces the risk of severe injuries or even fatalities that can result from such incidents.

RCDs are commonly installed in areas where electrical accidents are more likely to occur, such as bathrooms, kitchens, outdoor outlets, and areas with water sources. They are typically integrated into electrical distribution panels or incorporated into individual power outlets. RCDs are designed to provide a high level of protection and comply with specific safety standards and regulations to ensure their reliability and effectiveness.

It is important to periodically test RCDs to ensure their proper functionality. Most RCDs have a built-in test button that simulates a fault condition, allowing users to verify that the device trips and interrupts the circuit as intended. Regular testing helps ensure that RCDs are in good working condition and provides peace of mind regarding electrical safety.

Overall, the Residual Current Device (RCD) is an indispensable safety device that plays a critical role in safeguarding individuals from electrical hazards by swiftly breaking the circuit upon detecting a current imbalance.
