Resolution:
IGB ( Integral Ground Buss) utilizes two 1/16 inch thick ground bus bars to form the housing top and bottom. This provides an integral 50% continuous current capacity ground path. Equally important, the two ground bus bars completely encircle the phase conductors and provide a very effective high level ground path for ground faults. This grounding system is different from the old type on internal, separate ground bus bar system.
