Attach a ground wire from one of the threaded studs (A) at the bottom of the housing, to the mounting plate (B). Paragraph (d) of this section also applies to protective grounding of other equipment as required elsewhere in this Subpart. This helps to reduce the potential difference that exists between conductive parts and the earth. Equipment Protection: Grounding protects substation. Power from factory ground must be installed by a qualified electrician. Each DISTRIBUTION BOX and controller must be grounded. 26 mm 2 (10 AWG) ground wire must be used, and in all other markets a 6 mm 2 must be used. The concept is a simple one: provide a path for ground current via a resistance that limits the current magnitude, and. Abstract: Discussed in this recommended practice is the system grounding of industrial and commercial power systems. The recommended practices in this document are intended to provide explanations of how electrical systems operate.

For power transmission between the transformer and the low voltage switchboard, or from the main distribu tion board to the sub distribution board, trunking units of a busbar trunking system without tap off points are used. Primary distribution systems consist of feeders that deliver power from distribution substations to distribution transformers. At this. The electricity supply chain consists of three primary segments: generation, where electricity is produced; transmission, which moves power over long distances via high-voltage power lines; and distribution, which moves power over shorter distances to end users (homes, businesses, industrial sites. When a high level of flexibility is requested for trans mission, distribution, switching, and protection of electrical energy with, at the same time, low space requirements and a high reliability, the busbar trunking systems are the innovative alternative to conventional cable installations. And all the switching and protective devices are installed in the distribution box. A feeder can connect two substation buses in parallel to ensure stable power and continuous service for the loads from each bus.
