The idea here is slightly different from the general applications of contactor to electrical circuits, the said device is commonly used to make and to break electrical circuits automatically, it works for both single Phase and three Phase circuits, the difference between circuit breakers and contactors is that circuit breaker could only break automatically but cannot make until it is manually controlled, while contactors could. The technical innovation is the uncommon application of electrical contractors which are the switching off of generator when mains arrived and the ability to display indicators belonging to mains, generator and the load. Technical connectivities between the mains, generator and the load of contactor. The advantage of the connectivity is that the user will not need to get up to put off generator and to change over manually. All of that has been taken care of by the set up. The Prototype of the setup has been designed and constructed for result. Contactors are useful in commercial and industrial applications for controlling large lighting loads, for controlling motors, for fast changing over between electrical power sources and for Interconnectivity in power plants. Users of contactors will not have to move about to switch off generator and to change over power to mains when it is available, there will be no need for manual changeover device, working electrical and electronic devices would not be interrupted and one of their hallmarks is reliability. Contactor does not simply wear out from normal use. It prevents user from electric shock and there is no earthing.
