Today, in the era of technology and high-end devices that operate on a live electrical grid, it is considered considerably safer now than in previous years. The rapid and organized growth of the electrical industry has developed effective standards and safety procedures to mitigate different types of major hazards that have resulted in serious injuries and operators' death. Password based circuit breaker control system is a program that accesses only the password specified to trigger the breaker. Here, a provision is also made to change the password. The PLC and SCADA program manages the machine to the full. To enter a password and control relays a matrix keypad is interfaced with the PLC. The entire circuit is built with onboard power supply. The power supply is made of an SMPS. That transforms 230 V AC into 24 V DC and delivers it to PLC. Programming software is used for PLC programming and password configuration.
