摘要:
A device for providing ground fault protection for one or more loads in an electrical wiring system. The device includes a pickup for sensing electrical characteristics associated with conductors supplying power to the one or more loads and generating a pick up signal when predefined electrical characteristics are sensed; a ground fault detector powered using conductors that are independent of the conductors supplying power to the one or more loads, said ground fault detector being configured to receive said pickup signal, detect ground faults from said pickup signal, and generate a trigger signal when a ground fault is detected, and a power disconnect responsive to said trigger signal such that when said trigger signal is generated power to the one or more loads is disconnected. A corresponding method is also provided.
