Electricity, in essence, has become an indispensable part of our lives, but it comes with its own dangers, both to human life and to equipment in general. You cannot afford to neglect the safety factor when it comes to electricity, with electrocution and fire being two of the major risks associated with it. Having said that, when on the quest for electricity essentials for your home, you might have come across something known as an RCCB or perhaps seen your neighbour invest in one. Don’t exactly know what it is? Consider this blog your guide to everything RCCB and why it is important to have one on your power distribution board.
RCCB, an abbreviation used for Residual Current Circuit Breaker, is a crucial safety measure that ensures the protection of electrical circuits. It is a current sensing device designed to automatically measure and disconnect the circuit every time a fault occurs in the connected circuit. It also works if the current exceeds the rated sensitivity. RCCB is intended to protect people from electric shocks, electrocution, and fires, along with sudden earth faults by tripping the circuit immediately. Now that you know what an RCCB can do, let’s learn about its placement in your space’s electrical distribution box.
Inside the electrical distribution box, you can see RCCBs parallelly connected to MCBs. Here, the neutral connection is made to the neutral links, and the phase is connected parallelly with the MCB. This is because the MCB protects against overload and short circuits, whereas the RCCB protects against earth leakage. The neutral is required by the RCCB to detect both incoming and outgoing currents. A particular kind of distribution board known as PPI (Per Phase Isolation) offers a provision for installing RCCB in each phase as well as separate neutral links for every phase. This ensures that only the phase suffering a current leakage trips the RCCB, while the rest of the phases continue to work normally.
We are sure you must have thought about the impact of not having RCCB installed. If you have, let’s delve into understanding the significance of installing RCCB and how it enhances the safety and security of your electrical system and you as well.
We hope this blog helped you understand how crucial it is to have an RCCB in your distribution box. If you haven’t already purchased one, shop for the product at the best RCCB price from GM Modular now.
