How to Work On RCCB

Accepted Answer

RCCB stands for Residual Current Circuit Breaker. It is an electrical safety device used to protect against electric shock.

RCCB is installed in the electrical distribution board.
It detects and quickly interrupts the circuit if there is a leakage current.
To work on RCCB, follow these steps:
1. Ensure the power supply is switched off.
2. Open the electrical panel and locate the RCCB.
3. Check for any visible damage or loose connections.
4. Test the RCCB using a test button or a dedicated RCCB tester.
5. If the RCCB trips, investigate the cause of the leakage current.
6. Repair or replace faulty components if necessary.
7. Close the electrical panel and switch on the power supply.
8. Verify the proper functioning of the RCCB.
Example: If an RCCB trips frequently, it may indicate a faulty appliance or wiring issue.

Accepted Answer

RCCB is an electric current sensing device. It can automatically measure the amount of current and disconnect the circuit when there is a fault in the connected circuit or when the current surpasses the rated sensitivity. RCCBs prove to be especially helpful in case of a sudden earth fault.
