How to ground the primary power distribution box on a construction site
Single-point grounding is the preferred method because it generally yields the lowest potential difference in the work zone and because it usually requires less grounding equipment and effort to install. The protective grounding system, which includes conductor grounds and worker bonding, must be engineered to protect workers from hazardous voltages that can be created by line reenergizing, lightning, or induced oltage. If more than one crew is working independently on the same deenergized line or. IPMENT, STRUCTURES, ETC. IN ELECTRICAL STATIONS INCLUDING TRANSMISSION AND DISTRIBUTION SUBSTAT GR 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. Grounding and bonding limit overvoltages, stabilize the voltage to the ground during regular functioning, and ease the proper operation of circuit breakers and fuses. All grounding and bonding work must comply with NEC Article 250.
