PGE_Construction_Sketch.pdf

This document is a construction sketch for a Pacific Gas and Electric Company (PG&E) electrical service upgrade, specifically detailing electrical infrastructure modifications for a site located on Park Avenue in Napa, California. The sketch outlines a comprehensive electrical service upgrade involving the installation of a 50kVA transformer, removal of existing service infrastructure, and installation of a new 400A meter panel. The project includes trenching to install new underground cable, cutting and abandoning existing underground service, and removing and replacing various electrical components.

The technical diagram provides precise details about the electrical infrastructure, including specific measurements, cable types (1-4" duct cable), and service specifications. The sketch includes a legend describing installation and removal activities, with notes about underground service requirements, coordination with utility inspectors, and typical electrical trench configurations. The document includes mapping notes, meter information, and technical specifications such as voltage, load, and transformer details, suggesting a detailed engineering approach to the electrical service upgrade at the Napa Fire Station #2 location.
