Electric circuit operations are quite complex, thanks to the multiple wires and connections done in a properly, be it a domestic connection or a commercial one. Even though proper electrical connections are very much essential for a smooth and hassle-free lifestyle, an improper connection can lead to severe injuries, and even death.
Sometimes, current can flow in the opposite direction or in another circuit, thereby causing overheating or short circuiting. Such situations are also dangerous. This is why nowadays RCDs are installed for testing purposes.
These are nothing but safety electrical switches which can automatically shut down the electric flow from a circuit once it detects a fault in the electrical connection. Even though the use of RCDs has become mandatory in both residential and domestic properties, not everyone is aware of RCD testing.
This is why our forthcoming discussion will revolve around various aspects of RCD testing, the types of RCDs, the benefits of the testing processes of the RCDs, and other relatable facts. So, without wasting any further time, let’s focus on the impending talk in hand.
What is RCD and how does it work?
Before learning about this electrical component testing, you need to understand the basics of the equipment itself. RCD or the residual current devices are electrical components which can control the level of current entering every circuit connected to the main supply.
Every circuit has a certain threshold limit of current. If somehow the current entering a circuit increases than the threshold limit, the RCDs immediately switch off the supply, thereby preventing overheating and short circuits.
Similarly, if the electric current is flowing in an unintended path, like a person’s arm, the RCD will immediately cut off the power source, thereby helping to avoid serious accidents and death.
What are the types of RCD?
In the market, you will find several types of RCDs even when their functions are almost the same.
- Fixed RCD: These are usually fitted into the fuse box and are present in-built into the MCBs and MCPs. Hence, these RCBs will be connected to the entire circuit system of a property, providing the maximum level of protection.
- Socket-outlet RCD: These are connected into individual circuits at the time of fault detection, installation, and so on. It protects the person working on the circuit from any kind of electrical accident.
- Portable RCD: Portable RCDs can be used in standard socket circuits to protect an appliance mainly connected to a particular circuit.
What is RCD testing?
RCD testing is defined as an experimental study to understand where the fault lies and which particular circuit has been shut-off due to overflowing current or unintentional pathway. As a complete commercial or residential circuit system consists of multiple RCD devices, it is essential to carry out the examination for the fast detection of faults and then fix the issue at the earliest. Also, the test is done where the RCDs are tripped and then observed to ensure that in future, the device will protect the electrical circuits easily with no hassle.
How is the RCD testing beneficial?
- With the RCDs connected to the commercial or domestic circuits, one will be able to prevent the electrical accidents and even the deaths.
- RCD testing will help in detecting whether the component will be able to protect the appliances and other components from overloading and other serious issues or not.
- When multiple RCDs are connected, checking their fail-safe system helps the professionals to decide the site of fault and the root cause behind the same.
Conclusion
RCD testing might be a new concept for many people. But, it has helped the electrical professionals to safely design and built the circuits with no hassle. So, if you too want to make your property safe and ensure its longevity, you need to get the best professional who can carry about the RCD testing procedure easily.
