Standard grounding connection method for enterprise power distribution boxes

Standard grounding connection method for enterprise power distribution boxes

Attach a ground wire from one of the threaded studs (A) at the bottom of the housing, to the mounting plate (B). Abstract: Discussed in this recommended practice is the system grounding of industrial and commercial power systems. For commercial and industrial systems, the types of power sources generally fall into four broad categories: Utility Service: The system grounding is usually determined by the secondary winding configuration of the upstream utility substation transformer. During the manufacturing process, metal enclosures typically have fixed points welded to the base plate or side walls.
