Earth bonding test
WebFeb 23, 2013 · The 23K test is to determine whether or not the service is introducing the general mass of earth. If it is,and requires bonding,the 0.05 ohm test is to ensure minimal resistance between it and the electrical earth and hence minimal voltage difference. 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 …
