25 - UH1.2 - Grounding Assembly for Pad-mounted Transformers and Enclosures 2 Rods - Aug 2016.pdf

This is a technical drawing for a Grounding Assembly design for padmounted transformers and enclosures, dated August 2016. The schematic details a two-rod grounding system with specific installation requirements, including a minimum driven depth of 7-6" in earth and a minimum horizontal spacing of 6'-0".

The drawing includes a materials list specifying two connectors, two ground rods, two ground rod clamps, and ground wire as required. Two key technical notes are highlighted: (1) concentric neutrals must be tied together before grounding, with the ground loop sized to ensure adequate cable neutral conductivity, and (2) multiple rods may not fit inside the enclosure, with only one rod permitted to be installed inside. The technical specification is labeled as RUS standard drawing UH1.2, indicating it is likely a Rural Utilities Service standardized grounding assembly design.
