Glossary Of Terms


An extra insulated equipment grounding conductor run in the same conduit or raceway as the supply conductors and separate from the normal equipment grounding conductor. This conductor is insulated from the metallic raceway and all ground points from its origin at the grounding point in the main entrance to its termination at a special isolated ground-type receptacle. The theory is that by grounding sensitive electronic equipment with a separate isolated grounding wire, noise caused by currents flowing on the normal grounding system will not affect the sensitive equipment. There is no firm evidence that this extra isolated ground wire contributes substantially to better equipment operation. (see: Common Mode Voltage; Ground; Noise; Isolation; Main Entrance.)
