What can be used as a grounding conductor for a distribution box
26 mm 2 (10 AWG) ground wire must be used, and in all other markets a 6 mm 2 must be used. There are several factors that make substation grounding absolutely necessary. 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. Part VI of NEC's Article 250 states the rules for equipment grounding and equipment grounding conductors. Each DISTRIBUTION BOX and controller must be grounded. Per standards like IEC-60446, AS/NZS 3000:2007 3. 3, and BS-7671, grounding. The grounding system provides a low-impedance path for fault current and limits the voltage rise on the normally non-current-carrying metallic components of the electrical distribution system.
