Abstract
An electrical safety apparatus includes a ground fault circuit interrupter (GFCI) module, a timer module and a housing without a display screen. The GFCI module includes a sensor configured to output a differential current signal according to a current flowing to and from an electrical load, a ground fault circuit interrupter circuit in electrical communication with the sensor, and one or more switches arranged on one or more communication paths for supplying power to the electrical load. The timer module is in electrical communication with the GFCI module and configured to generate a timer signal. Responsive to the differential current signal or the timer signal, the ground fault circuit interrupter circuit generates a driving signal to selectively open or close the one or more switches. The housing encloses the GFCI module and the timer module.
