Residual Current Device or RCD is one of the most important safety features in many households today. Along with fuses and circuit breakers, more and more people installed these safety devices to actually save life and property. But RCD is mainly different from fuses and circuit breakers for the primary reason that RCD focuses in preventing accidents toward people more than properties.
If you still do not have RCD installed in your house, then you might be putting yourself and family in danger. While the danger might not be obvious for the moment, you will regret not having an RCD as soon as you get electrocuted. For this reason, this article will present to you the three benefits of RCD. But before that, let us first know what an RCD is.

What is RCD?
The definition you might read in other books might be too complicated to understand so this article will give you a simple and straight forward answer. RCD is basically a circuit breaker that cuts the electric current every time there is an abnormal flow of electricity. It is really simple. For safety purposes, the live wire and neutral wire should not get in contact with each other. In normal conditions, there should be a balanced electrical current between the live wire and neutral wire. But in case you get in contact with the live wire, the current from the live wire will connect to the earth through your body and eventually connect to the neutral wire. The abnormal shift of current will immediately be detected by the RCD and in less than a second, the RCD will switch off the electric flow, thus saving you from being badly electrocuted.
Benefits of RCD
Now that you know what RCD is and what it does, the benefits of RCD are pretty obvious. But for the sake of discussion, the following are the benefits of RCD.
These are just some of the benefits of RCD. Do not underestimate its importance and make sure you installed RCD in your house.
