5.2 Ground Loop Problems Before installing the CAT5 ClassWork Plus, check for ground loop problems. These are caused by having equipment connected to different ground points via interconnected cables. If the difference in ground potentials (voltage) is great enough, it can create a current sufficient to cause the problem. -
Page 19: Ground Loop Solutions
CAT5 CLASSWORK PLUS 5.3 Ground Loop Solutions • Have a qualified professional measure the AC and DC voltages between the ground points.
