Troutdale gets the weather that funnels out of the Columbia Gorge, so if your charger mounts outside or in a detached garage, the hardware needs to be rated for it. We use weather-rated hardwired units for exposed spots, run the circuit in outdoor-rated conduit, and mount it so wind-driven rain is not sitting on the connection. It is a small detail that keeps an outdoor charger reliable through a wet, windy east-county winter instead of nuisance-tripping every time the weather turns.
The load check comes first, and any service work runs through your utility. Troutdale is Portland General Electric territory, so a heavier service is coordinated with PGE, and the city runs its own building program under an agreement with Multnomah County, so the permit and inspection stay with the city. We coordinate the PGE meter work and the city inspector together. Any current PGE rebate runs through the utility, so check current availability.
