All ground conductors should connect directly to the MGB including all power sources and communication equipment. Avoid DAISY CHAINING ground conductors. If a single Ground Rod doesn't get you to 5 ohms or less, consider putting in multiple ground rods or even a Halo. . In the United States the term “Grounding” can mean many different things, depending on the electrical applications. Ground wire is ran for. . Note: In numerous test on soil with uniform soil resistivity it has been found that ground's resistance is at around 62% (some documents says at 61. 8%) away from the rod under test!! Hence Fall of Potential Method is also known as 62% Method of Ground Resistance Testing. 94 and TIA/EIA requirements type. Ground res stance shall not exceed 2 ohms unless approved by UN ed so that the TBB for telecommunications is as short and str BC shall be Green insulated conductor sized from Tab ri minimum. . A. Connecting the communications system and permanently joining all that metal conducting portions of the communications pathway to earth in such a manner as to prevent potential electrical loops and transients that can cause damage to telecommunications equipment, networks and personnel.
