About this file
This is a set of electrical drawings detailing upgrades to internal building transformers and disconnect switches at the USDA Agricultural Research Service Northwest Irrigation & Soils Research Laboratory in Kimberly, ID. The drawings include a project cover page, electrical site plan, and electrical single line diagrams showing both removal work and new work to be performed.
The drawings specify replacement of multiple transformers ranging from 9KVA to 75KVA across several buildings including the Main Building, Head House, Irrigation Lab, Vehicle Storage, and Greenhouse facilities. Key work includes removing existing floor and wall-mounted transformers while retaining primary/secondary conductors, installing new transformers with proper wall brackets and disconnect switches, replacing aluminum wiring with copper, and providing new bonding cables sized appropriately for each transformer capacity (#8AWG for 30KVA, #4AWG for 45KVA, #2AWG for 75KVA transformers). The drawings include detailed general notes about wire replacement requirements, grounding specifications, and working clearance requirements per NEC 110.26(A)(1).
