Panel Upgrades in Sammamish, WA
Modern homes pull more power than 100-amp panels were built for. We upgrade to 200-amp service with clean, labeled, inspection-ready work.
A lot of Plateau homes built from the 1980s onward are now old enough for their first panel replacement, especially in households adding an EV charger or heat pump. We pull the permit and handle the inspection so the upgrade closes out clean.

- Breakers trip when the AC and oven run together

Panel Upgrades in Sammamish: what's different here
Plateau homes from the 1980s and 1990s usually have 150 or 200-amp service, but adding an EV charger and a heat pump together still calls for a load calculation. Most Sammamish homes have 150 or 200-amp service. When an EV charger and heat pump together push past that, we upgrade the panel or install a load management device.
Permits and inspections
A panel upgrade always needs an electrical permit and a final inspection. Sammamish runs its own electrical permit and inspection program, so permits for this work go through the City of Sammamish rather than Washington L&I (L&I list of cities). We pull the permit and meet the inspector.
