Protective Grounding Set Tester

Self-contained, portable convenience. This tester provides an easy way for an electric utility to check the resistance in protective grounding sets used by line personnel. Powered by 120 VAC, the tester applies Direct Current across the test specimen.


Procedure details are given in the instruction manual. All components store in the tester’s integral carrying case. Simple, one-button testing from pushing a single button, the digital display shows the resistance measured in milliohms compared with a preset threshold for the size grounding cable selected (#2, 1/0, 2/0 or 4/0).
