Abstract

Systems and methods for providing ground fault detection in HVAC and other types of equipment allow an appropriate or safe level of grounding conductor leakage current from the equipment while at the same time providing let-go current protection for branch circuit conductors feeding the equipment. In some embodiments, the systems and methods herein are implemented in the form of a ground fault interrupting system that is specifically designed to operate outdoors, and may be installed at the equipment outlet disconnect device typically mounted on an exterior wall near the equipment. In some embodiments, the ground fault interrupting system incorporates the outlet disconnect device therein. In either case, the ability of the ground fault interrupting system to be located outdoors near the equipment allows technicians to more easily install, access, and service the ground fault interrupting system compared to an indoor arrangement.
