WebFigure 7 shows a representation of the ground bond test. Figure 7 - Ground bond test in class I equipment . For fixed installations a point-to-point continuity measurement can be made by fitting a second lead into the aux ground socket. The resistance is then measured between the two leads. The IEC 62353 requires a minimum test current of 200mA ... WebTesting electrical bonds. It's been almost 45 years now, and the world of electrical testing has changed so much during that time. In this column, I'll revisit the test techniques I used in 1963 at an aerospace company, and compare them to today's tools and methods. My example is the process for testing the electrical bonds required in ...
