ABSTRACT:
A portable ground fault interrupter is provided which includes a strong environmentally durable housing and plug inputs for plugging into an electrical outlet. The housing also contains receptacles to accept an electrical plug. A plurality of first electrical contacts are within the housing and stationary relative to the housing. A second plurality of electrical contacts corresponding to said first contacts are suspended within the housing by electrical conducting strips which biasingly move the second contacts away from the first contacts. A latching assembly selectively and operably engages said second contacts to overcome the force of the suspending strips to move the second contacts into electrical engagement with the first contacts. Occurrence of a ground fault removes the latching assembly from engagement with the second contacts breaking electrical contact between the first contacts and second contacts.
