Oregon City's geography splits the panel work as cleanly as its history does. Below the bluff, in Canemah, the McLoughlin Historic District, and downtown, the homes are old and often on small overhead services where the mast and grounding are as dated as the panel, so a real upgrade rebuilds the service, not just the box. Up on the hilltop and along Beavercreek Road, the newer subdivisions generally have underground service and modern panels, so the work there is more often a subpanel or added capacity.
Wherever you sit, your power comes from Portland General Electric, so a heavier service is coordinated with PGE at the meter. Oregon City is unusual among Clackamas County cities in running its own electrical program, so the permit and inspection stay in-house with the city rather than going to the county. That means we are lining up the PGE disconnect and a city inspector, and knowing the city handles its own inspections keeps the timing tight.
