To perform the test, have on hand two rolls of #8 wire, one 175 ft and the other 250 ft. Which roll to use depends on the distance to longest test point. WebNov 1, 2007 · Earth bond testing . One of the main differences is the use of a minimum test current of 200 mA for earth bond testing, compared with 25A required in IEC 60601-1. This test is designed to test the integrity of the low resistance connection between the earth conductor and any conductive metal parts, which in Class I devices may become live …

WebJan 1, 2000 · A ground test showed 25 ohms to earth ground from the building steel, 180 ohms to earth ground from the transformer. Amazingly, there was an open circuit from the machine to the main ground! How can there be an open circuit with the machine's ground rod in place? That ground rod, for lack of bonding to the rest of the system, was irrelevant. WebThe Grounding Continuity Test (aka Earthing Continuity Test) is one of the most common product safety tests. It is performed on products that have a ground (earth) connectionby … i-master thales
