WHAT IS RCCB AND WHY WE SHOULD WANT TO USE IT IN DB?

RESIDUAL CURRENT CIRCUIT BREAKER (RCCB)

A Residual. Current Device (RCD), or Residual Current Circuit Breaker (RCCB), is an electrical wiring device that. Dis-connects a circuit whenever it detects that the electric current is not balanced between the phase 

How RCCB is use-full for us?

1. It has a switching device that does not return through the neutral whenever the current goes out.

2. RCCB provides protection from small current leaks that may arise due to accidental touch or backup failure of a human, not only by MCB or FUSE

LCETED TRIVIA

RCCB Rated Currents from 16A up to 125A

Why Is It Necessary?

There are two types of electrical faults which are very dangerous.

1.  High Current Fault Due To Some Short Circuit Current

2.  Earth Leakage Arises Due To Wet Hands Touched By Someone

High current fault due to some short circuit current can be protected by an MCB. but MCB cannot detect earth leakage arises due to wet hands which can be detected by RCCB

NOW YOU MAY HAVE  A IDEA OF WHAT IS RCCB AND WHY TO USE IT. SO WE LCETED WILL WANT YOU TO KNOW ABOUT RCCB LIMITATIONS ALSO BEFORE USING IT

1.The RCCB does not protect from the excessive heat that can occur if the conductors are not properly screwed into the terminals.

2.RCCB does not protect against current burdens. Designed to protect only when direct current and neutral current are different. However, current loads cannot be detected.

RCCB Are Of Two Types; The 2 Pole RCCB And 4 Pole RCCB.

2 Pole RCCB: This is used in case of a Single-Phase Supply Connection that has only a live and a neutral wire.

4 Pole RCCB: This is used in case of a Three-Phase Supply Connection.

OK

Now If You Are Civil Engineer, You Should Know How To Wiring Of The Distribution Board With RCCD – Single Phase Home Supply

LCETED WILL HELP YOU ON IT

CONCLUSION BY LCETED

Therefore, RCCB is extremely important in providing real-time protection for circuits. Especially in high-voltage industries and commercial configurations, its importance cannot be undermined as there is always the risk of accidental shock and death as a result.
