The paper is designed for access control with help of password only the electric safety system makes use of a new password it is found that fatal electric accidents to line man are increasing during the electric line repair. Due to lack of communication and co-ordination between the maintenance staff and electric substations staff. This system is also useful for if any accidents happen in industry .for example short circuit then there is very critical to handle the situation .most important thing the supply is quickly turn off by without manpower through password. Hence to avoid this password based circuit implemented
