RCD TESTING

An RCD, known as a Residual Current Device, is an electrical safety device that plays a crucial role in protecting against electric shocks and fire hazards. It continuously monitors the flow of electric current within a circuit and rapidly shuts off the power supply if it detects any imbalance between the outgoing and returning currents. By swiftly interrupting the power, RCDs help prevent potentially dangerous situations and enhance electrical safety in various settings, including residential, commercial, and industrial environments. There are several types of RCDs available, each designed for specific applications and electrical systems. The common types of RCDs include:

1. Fixed RCDs: These are permanently installed RCDs and provide protection to a specific circuit or group of circuits in a building. They are typically found in distribution boards or switchboards.


2. Portable RCDs: Also known as plug-in RCDs or portable safety switches, these devices can be easily plugged into a standard power outlet. They are commonly used with portable electrical equipment, extension cords, and power tools to provide portable protection.


3. Socket Outlet RCDs: These RCDs are integrated into power outlets and provide protection for specific socket outlets. They are commonly used in areas where additional protection is required, such as outdoor sockets or in wet environments.
