Types of RCDs: Portable vs Fixed RCDs Explained

When it comes to electrical safety, Residual Current Devices (RCDs) are among the most effective protective measures. They detect imbalances in the electrical current and quickly shut off the power supply to prevent shocks, burns, or even fatal accidents. But not all RCDs are the same—depending on the setup and use, you’ll come across two main types: Portable RCDs and Fixed RCDs.

What is an RCD?

An RCD (Residual Current Device) is a life-saving safety device designed to cut off electricity within milliseconds when it detects leakage current flowing to earth. This rapid response reduces the risk of severe electric shock and helps prevent electrical fires. To Know More Click Here

Portable RCDs

Portable RCDs are simple plug-in devices that connect directly into a power socket. They provide quick and easy protection without requiring installation or wiring changes. Because of their portability, they are perfect for temporary use, such as when operating power tools, gardening equipment, or outdoor appliances.

The biggest advantage of portable RCDs is convenience—they’re lightweight, affordable, and can be carried anywhere. However, they only protect the specific appliance plugged into them, which means they cannot offer complete safety across an entire home or workplace. To Know More Click Here

Fixed RCDs

Fixed RCDs, on the other hand, are permanently installed in a property’s main switchboard or consumer unit. They offer wider protection by covering multiple circuits at once, ensuring that all connected appliances and outlets are safeguarded.

These devices are far more reliable for long-term safety. A fixed RCD not only protects against shocks but also significantly lowers the risk of electrical fires caused by faulty wiring. The downside is that they require professional installation and cost more upfront, but the level of protection they provide makes them essential for homes, offices, and commercial spaces.

Which One Should You Choose?

The choice between portable and fixed RCDs depends on your needs. If you require temporary, flexible, and low-cost protection for specific equipment, a portable RCD is a practical solution. But if you’re looking for complete, long-lasting safety for your property, a fixed RCD is the smarter investment. To Know More Click Here

Final Thoughts

Both portable and fixed RCDs play a vital role in reducing electrical risks. Portable RCDs are best for short-term, on-the-go protection, while fixed RCDs provide comprehensive, permanent safety. Whichever you choose, remember that electrical accidents can happen in seconds—having the right RCD in place ensures you and your loved ones stay protected.
