Electrical accidents are rapidly increasing especially electric line repairs, incident due to the lack of communication and coordination between the maintenance personnel and the electric substation staff. The password based circuit breaker device could just be the solution as only the lineman could reliably control the circuit breaker to avoid miscommunication. The system requires a password to turn ON/OFF the circuit breaker as needed. Password Based Circuit Breaker is design to protect a circuit from damage which is caused by over load or short circuit. Many fatal electrical accidents are happen due to miscommunication between the maintenance staff & the electric substation staff. To avoid accidents, it is designed in which only authorized person can operate it with the help of a password. The password based circuit breaker is a system that access only specified password to control the circuit breaker by authorized person only. Here, there is also a provision of changing the password. The system is fully controlled by the arduino processor for the program memory. A matrix keypad is used to enter the password and relay driver IC is used to switch ON / OFF the loads through relays.
