Panel Upgrades in Mercer Island, 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.
Panel upgrades on Mercer Island have to account for the island's terrain as much as the house itself — a lakefront home near 18 feet of elevation and a ridge-top house near Rotary Park can both need a 200-amp upgrade, but the conduit run and access are rarely the same job twice.
Symptoms we see every week in Mercer Island
- Breakers trip when the AC and oven run together
- Still on a 100-amp or fuse-based panel
- Adding an EV charger, heat pump, or ADU
- Panel is unlabelled or has doubled-up breakers

Panel Upgrades in Mercer Island: what's different here
The island's mix of older lakefront homes and large remodels means panels range from original 100-amp service to newer 400-amp service. Many older Mercer Island homes still have 100-amp or fuse panels. Adding a heat pump, EV charger or kitchen remodel usually means upgrading to 200 amps. We do the load calculation, pull the permit and coordinate the disconnect with PSE.
Permits and inspections
A panel upgrade always needs an electrical permit and a final inspection. Mercer Island runs its own electrical permit and inspection program, so permits for this work go through the City of Mercer Island rather than Washington L&I (L&I list of cities). We pull the permit and meet the inspector.
