Abstract:
An electrical safety system with an integrated timer is disclosed. The electrical safety system may have an input line connected to an output via one or more communication paths. The electrical safety system may also have a ground fault circuit interrupter module including a sensor coil for monitoring current passing from the input line to the electrical load and producing a current signal and a ground fault circuit interrupter circuit. Further, the electrical safety system may have one or more switches for opening or closing the one or more communication paths between the input line and the output, and a solenoid for operating the one or more switches. Additionally, the electrical safety system may have a timer module comprising a timer circuit configured to generate a timer signal and a selector switch in electrical communication with the timer circuit and a visual display.
