Hubbell's Circuit Guard GFR5352WL is a commercial specification grade ground fault receptacle designed for enhanced safety and reliability. Unlike competing models, this receptacle utilizes a functional LED indicator that rapidly flashes red to signal a test failure, providing a clear visual alert. The design incorporates Hubbell’s unique “Comprehensive Whole System Test Function,” which tests both the electronic components and the mechanical trip mechanism, verifying the device's ability to sense and interrupt ground faults. Suitable for commercial applications, this receptacle ensures a valuable safety message and quick installation with its compact size.
