  • Distribution box grounding test

    Distribution box grounding test

    Attach a ground wire from one of the threaded studs (A) at the bottom of the housing, to the mounting plate (B). Specialized earth testers, like the Fluke 1630-2 FC Earth Ground Clamp and the Fluke 1625-2 GEO Earth Ground Tester, are the troubleshooting tools built to make earth ground tests a lot easier. How do you perform. Measuring ground resistance using a multimeter is generally not as accurate as using specialized ground resistance testers, but it can provide a rough estimate. Here's a basic guide on how to measure. There are several factors that make substation grounding absolutely necessary. Each DISTRIBUTION BOX and controller must be grounded. 26 mm 2 (10 AWG) ground wire must be used, and in all other markets a 6 mm 2 must be used. The National Electric Code (NEC), Article 250, contains specific requirements on the grounding of electrical power systems and equipment.
