What You Need to Know About Residual Current Devices
Definition of RCD
A residual current device or RCD is a device that is designed to save life. It is basically used to inhibit you from being electrically shocked when you touch a thing that is like such as a bare wire. It can also work by protecting you from electrical fires. The residual current devices can protect you more than the circuit-breakers and ordinary fuses do.
How Does an RCD Function
A residual current device is a safety device that turns off electricity automatically during a fault. Electrocution and fire are just two of the possible effects of earth faults. The RCD is designed to protect people and properties from these two. For example, the RCD can protect you if you are mowing in your lawn and you cut through the cable and become exposed to bare wire. The same can also help you when you have an electric appliance that overheats.
How Do Residual Current Devices Do It?
The residual current device is designed to constantly and consistently monitor the flow of the electric current going through the circuits for which it is intended to protect. The moment it detects electricity flowing out of line, it will switch off the circuit right away. With the presence of this life-saving the device, the chance of getting serious injury or drying to fire or electrocution can be significantly reduced.
Is the RCD Reliable?
According to researches, almost 100% of RCDs are reliable. And with regular testing, that performance can even improve considerably. That is why if you have installed RCD for the sake of protection, it will definitely help reduce the possibility of electric shock. It can also safeguard your home from catching fire.
You need to remember, however, that even though residual current devices is meant to protect your property from risks that are brought about electrical faults, they are not designed to make you less careful. To ensure of safety, you need to have your wiring checked at least once in 10 years. By the moment you are able to detect fault in your electrical appliance or in your wiring, you should stop from using it right away.
And for you to be able to make sure that your residual current devices are still in their best working condition, you should consider testing them once for every three months. In the case with portable residual current devices, they must be tested every after use. Most RCD manufacturers recommend so. Last of all, you need to see to it that you are procuring your residual current devices from a trusted and well-reputed manufacturing company.
