Panel Upgrades in Mercer Island, WA
Panel upgrades on Mercer Island usually come up when a remodel, an addition, or a new EV charger pushes past what the existing panel can carry. We replace outdated panels with 200-amp Square D QO service, pull the Mercer Island permit, and coordinate the service side with Puget Sound Energy.

Mercer Island homes range from mid-century originals to large renovations and new builds, and many have been expanded more than once. That history shows up in the panel: an original box that was fine for the house as built, then asked to carry a bigger kitchen, a finished lower level, more lighting, and now a Level 2 charger. On the North End, the South End, and around First Hill, a renovation is often the moment a homeowner learns the panel is full or the service is undersized for what they want to add next.
Permitting runs through the City of Mercer Island Building Division, and power comes from Puget Sound Energy (PSE). We pull the permit, coordinate the service drop or lateral and meter base with PSE, and schedule the rough and final inspections. Our standard residential upgrade is a Square D QO 200-amp, 40-space panel, with the service entrance and grounding brought up to current code and GFCI and AFCI protection where it is required. Most upgrades are finished in a single day, with power off for a few hours during the swap.
If you are planning a remodel, it usually makes sense to time the panel work with the renovation so new circuits land in a panel with room to spare. We look at your existing panel and what you plan to add, then recommend the simplest safe option. Call All City Electric at (206) 533-6333, Monday through Friday, 8:00 to 4:30.
Panel Upgrades in Mercer Island: Your Questions
Do I need a permit to upgrade my panel on Mercer Island?
Yes. A panel or service upgrade requires an electrical permit and inspection. We pull the permit through the City of Mercer Island Building Division, schedule the rough and final inspections, and coordinate the service side with Puget Sound Energy so you are not chasing anyone.
Should I upgrade my Mercer Island panel before or during a renovation?
Usually during. When a remodel adds circuits for a kitchen, lower level, or EV charger, upgrading the panel at the same time means the new wiring lands in a 200-amp, 40-space panel with room to grow, instead of squeezing into a box that is already full.
How long will my power be off during the upgrade?
Most residential service upgrades are completed in a single day, with power off for a few hours while we swap the panel and meter base. We tell you the window ahead of time so you can plan around it.
Which panel do you install?
We install Square D QO professional-grade panels and breakers, using a 200-amp, 40-space panel as our standard residential upgrade. They are reliable, widely available, and easy for any future electrician to service, and every circuit is labeled when we finish.

"I had an incredible experience getting service done from All City Electric. I wanted to have some outlets fixed as well as install a Level 2 Charger. They were easy to schedule a time for an estimate and also for the service. The electrician came right on time for both appointments and was very respectful and sweet. Every team member was very kind and sweet and accommodating. I would highly recommend them for any future service needs you have!"

"I called All City Electric when my laundry room and living room lights would not turn off. If you tried to turn them off they flicker. Then 5 of my outlets either didn't work or things would fall out of them. I finally got sick of it and reached out explaining my situation. The gal that answered my call was very sweet and kind. Even when I called back the next day saying I forgot to write it down and wanted to confirm my appointment day and time. We had a good laugh. She made my day! Today, Kevin showed up on time and confirmed the problem and got to work right away. He was pleasant and kind during the entire process. He answered all my questions. Thank you to the entire staff and owner of All City Electric!! You will forever have my business. Please call if you have any issues. They are absolutely the best to work with!! Thank you again!!"
