Grounding of junction boxes on each tower
Junction box grounding requirements are strictly defined by NEC Section 250. 148 to ensure that all metallic parts are bonded, providing a low-impedance path for fault current. The system is composed of 3 towers arranged in a daisy chain setup. Each tower has a grounding system. Any repairs, alterations or substitution of recommended parts made by the user to this equipment not approved by the manufacturer could void the user's authority to operate the equipment in addition to the manufacturer's warranty. When lightning strikes a tower, the surge of electricity must be directed away from sensitive equipment and structural. 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. Failure to correctly ground a box can lead to energized enclosures, posing severe shock and fire risks. The National Electrical Code (NEC), published as NFPA 70, sets minimum safety standards for electrical junction boxes in residential and commercial buildings.
