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, the project 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. A matrix keypad is used to enter the password and relay driver IC is used to switch ON / OFF the loads through relays.
