What Is an RCD (Safety Switch)? How It Works

An RCD, or Residual Current Device, is another critical safety component. It aims to protect individuals from electric shock caused by current leakage. This device monitors the electrical current flow in circuits.
Upon detecting an imbalance, it swiftly disconnects the circuit. It is more sensitive than a circuit breaker and acts before dangerous currents can cause harm. In Australia, RCDs are commonly referred to as safety switches.
Here’s how an RCD operates:

• Constant Monitoring: It keeps track of the current flowing in and out.
• Detects Imbalance: Any discrepancy is a warning sign.
• Instant Disconnection: It trips within milliseconds to cut off power.

RCDs are especially important in areas prone to moisture. Kitchens, bathrooms, and outdoor areas present higher risks of electric shock. Therefore, these environments must be equipped with RCDs for added protection.
Regular testing of RCDs is essential to ensure they work correctly. Pressing the test button should trip the device. If not, a qualified electrician should investigate and repair any issues promptly. These devices are a vital part of any comprehensive approach to electrical safety. Ensuring they function properly enhances safety measures for both residential and commercial settings.
