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.
