Grounding grid connection method for distribution boxes

Attach a ground wire from one of the threaded studs (A) at the bottom of the housing, to the mounting plate (B). The ground resistance between all system parts shall be <. Equipment Protection: Grounding protects substation equipment from potential damage from lightning strikes, fault currents, and transient overvoltages. The longevity and dependability of essential electrical components are both preserved with the assistance of this protection. System Stability: A. THAN 8 FT FROM THE FENCE. THE FENCE SHALL BE GROUNDED SEPARATELY FROM THE GRID UNLESS OTHERWISE NOTED ON THE A PROPRIATE PROJECT DRAWING. SEE APPLICATION "S",THIS DRAWING, FOR REQUIREMENTS FOR HIGH VOLTAGE TOWERS AND PO ES D BY GROUNDING ANALYSIS. The specific neutral grounding method chosen by the utility can have significant impacts on reliability of service, safety, protection coordination, power. The system grounding arrangement is determined by the grounding of the power source. 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.
