Service & Panel Upgrades for Seattle Homes
Electrical Panel Upgrade in Seattle, WA
Konsker Electric upgrades electrical panels and 200-amp services for Seattle, WA homes, licensed and bonded through Washington State L&I with a BBB A+ rating and more than 20 years in the metro. If your panel is tripping, you found a Federal Pacific or Zinsco label inside the door, or you are adding a heat pump or EV charger to a pre-1960 100-amp service with no room left, we handle it start to finish: a metered assessment at the panel, a load calculation per NEC Article 220, new service-entrance equipment, the NEC 230.67 whole-house surge device, and the Seattle City Light disconnect and reconnect timed so the meter comes back on the day the Seattle DCI inspection passes. You get a flat-rate quote in writing before any work begins, so the number you see is the number you pay.
Until now there was no dedicated Seattle panel-upgrade page on our site, even though homeowners here search for it constantly and land on a generic homepage. So we built the page we would want to read: straight answers on the signs a panel is failing, the real Seattle City Light and Seattle DCI steps, and an honest take on cost. No sticker prices pulled out of the air, no scare tactics. For the head-term details that apply across our whole service area, see our Seattle electrical panel upgrades service page. North-metro homeowners over the county line, where the permit runs through the City of Lynnwood and the utility is Snohomish PUD rather than Seattle City Light, can read our Lynnwood panel replacement guide instead. South-end homeowners in the Kent Valley, where the utility is Puget Sound Energy and the permit runs through the City of Kent, will find the local specifics in our Kent electrical panel upgrade guide. Eastside homeowners in wine country can get the same PSE-and-King-County walkthrough on our Woodinville panel upgrade page.
Is It Time?
Signs Your Seattle Electrical Panel Needs Upgrading
Some of these are inconvenient. A couple are genuine fire-risk failures. Here is how we tell the difference during a metered assessment in Seattle homes.
Breakers that trip under normal load
If the kitchen circuit drops every time the microwave and toaster run together, or the heat pump trips the main on a cold Seattle morning, the service is undersized for how the home is actually used.
Federal Pacific or Zinsco panel
Both designs have a documented history of breakers that fail to trip on a fault. We replace them, not service them back into use, because no new breaker fixes the underlying design defect.
Pre-1960 or mid-century wiring
Knob-and-tube, cloth-jacketed Romex, and aluminum branch wiring from 1965 to 1973 are common in Wallingford, Ballard, Queen Anne, and the Central District. A panel upgrade is often the first step in bringing that service up to code.
Still on a 100-amp service
A heat pump, an EV charger, or a finished basement can push a pre-1960 100-amp Seattle service past its headroom. A load calculation tells you whether you have room left before you add the load.
Heat, scorching, or a hot-plastic smell
A panel that is warm to the touch or shows scorched bus bars is failing at the lug connections. Shut the affected breaker off, not the plug, and call a licensed electrician before it arcs.
An older panel with no surge protection
NEC 230.67 requires whole-house Type 2 surge protection on new and replacement panels in Seattle. Older panels predate the rule, leaving sensitive electronics exposed to grid and windstorm-driven surges.
When a panel upgrade is the wrong call
Not every panel needs replacing. If you have a modern Square D, Eaton, or Siemens panel that is under 15 years old, has open breaker spaces, and is not showing heat or corrosion, adding one 240-volt circuit for an EV charger or a heat pump is usually a subpanel or a single breaker job, not a full service upgrade. Do not let anyone talk you into a new 200-amp service you do not need. We will run the load calculation first, and if your existing panel has the headroom, we will tell you that on the site walk and quote the smaller job instead. The upgrade is genuinely the right call when the panel is a Federal Pacific or Zinsco, when the service is a maxed-out 100 amps, or when the load math says you are out of room.
Not sure which camp your panel is in? Call a licensed electrician at (206) 260-1981 and we will meter it before we quote anything. If the panel is already sparking, arcing, or giving off a burning smell, don't wait for a scheduled assessment. That is a job for our Seattle emergency electricians the same night.
Federal Pacific and Zinsco panels get replaced, not serviced back into use.

What It Costs
Electrical Panel Upgrade Cost Factors in Seattle
A 200-amp panel upgrade in Seattle is estimate-driven, not flat-priced. We do not publish a single sticker number because the honest answer depends on the variables below, and quoting a figure before the load assessment would be guessing. After a metered assessment and a site walk you get a flat-rate quote in writing, and that is the number you pay.
One factor sets the floor more than the rest: whether you are simply replacing a panel or genuinely upsizing the service. A like-for-like 200-amp swap in a newer Ballard townhome is a contained job. A 100-to-200-amp upsize in a pre-1960 Wallingford or Queen Anne home pulls in the meter base, the service mast, and a Seattle City Light service-drop upgrade, and that is where the number and the timeline both climb. We tell you which one your home is before you commit. Prefer to talk it through now? Call (206) 260-1981.
Permits & Utility Coordination
Seattle City Light and Seattle DCI, Handled for You
Inside Seattle city limits the electrical permit runs through Seattle DCI rather than Washington State L&I, and the service disconnect and reconnect run through Seattle City Light rather than Puget Sound Energy. On a service upsize the City Light service application is the long pole in the schedule, running on the order of 6 to 10 weeks. We pull the permit, file the City Light application, and schedule the inspection. We do not leave the utility calls to you.
- Electrical permit filed with Seattle DCI, the correct authority inside Seattle city limits
- Seattle City Light service application filed early, since a service upsize can run 6 to 10 weeks through the utility
- Federal Pacific Stab-Lok and Zinsco panels replaced, not serviced back into use, per our stated policy
- Whole-house Type 2 surge protection at the service per NEC 230.67, standard on every replacement panel in Seattle
- Load calculation per NEC Article 220 and grounding brought to code per WAC 296-46B, documented before reconnect
Whether your home is a pre-1960 bungalow in Wallingford or Ballard, a Queen Anne box with knob-and-tube in the basement, or a Mount Baker Craftsman on a maxed-out 100-amp service, this is work we do across the city every week. A panel upgrade is often the first step in a larger retrofit, so we can fold it into panel replacement for older Seattle homes or an EV-charger circuit in the same project, and it pairs with the rest of our residential electrical work.

Common Questions
Seattle Panel Upgrade FAQ
Do I need a permit for a panel upgrade in Seattle?
Yes. A service or panel upgrade is permitted electrical work, and inside Seattle city limits that electrical permit runs through Seattle DCI (the Department of Construction and Inspections), not Washington State L&I, because Seattle is its own electrical authority. As an electrical contractor licensed through Washington State L&I, we pull the Seattle DCI permit, schedule the city inspection, and coordinate the service disconnect and reconnect with Seattle City Light. The new panel, the grounding and bonding, and the whole-house surge device all have to pass a Seattle inspection before the meter is energized, so this is never a job to run unpermitted. Seattle also enforces its own local amendments on top of the NEC as adopted by Washington, which is one more reason to have the permit handled by someone who works inside the city every week.
Should a Federal Pacific or Zinsco panel be replaced in a Seattle home?
Yes, replaced, not repaired. Federal Pacific Stab-Lok and Zinsco panels are common in Seattle homes built or remodeled between the late 1960s and early 1980s, and both designs have a documented record of breakers that fail to trip reliably on an overload or short circuit. That is a fire-risk failure mode you cannot fix by swapping in a new breaker, so our stated policy is to replace these panels with modern service-entrance equipment rather than put them back into service. If we find one during a metered assessment in a Wallingford box or a Ballard bungalow, we tell you plainly and quote the replacement with a written cause-of-failure note.
How long does a panel upgrade take with the Seattle City Light service application?
The on-site electrical work for a typical Seattle 200-amp service upgrade runs most of a single day: old panel out, new service-entrance equipment and panel set, every branch circuit re-landed and torqued to spec, grounding and bonding redone, and the NEC 230.67 surge device added. What sets the calendar is the front end. A Seattle City Light service application, especially when you are upsizing the service, can take on the order of 6 to 10 weeks to move through the utility, and the Seattle DCI permit and inspection sit alongside that. We file the paperwork with both authorities up front and give you the realistic full timeline in the written quote, not just the wrench time.
What are the signs my Seattle home needs a panel upgrade?
The clearest signs are breakers that trip when you run normal loads together, a panel that is warm to the touch or smells faintly of hot plastic, lights that dim when the heat pump or oven kicks on, and a service that is still 100 amps in a home that has added a heat pump, an EV charger, or a finished basement. The non-negotiable ones are a Federal Pacific Stab-Lok panel, a Zinsco panel, or aluminum branch wiring from the 1965 to 1973 era, all common in pre-1960 and mid-century Seattle housing stock. We start every assessment metered at the panel with a Fluke meter and finish with a written cause-of-failure note so you know exactly why the upgrade is the right call.
How much does a 200-amp panel upgrade cost in Seattle?
Panel and service upgrades are estimate-driven, not flat-priced, because the honest number depends on whether you are upsizing the service from 100 to 200 amps or swapping like-for-like, how far the panel sits from the meter, whether the meter base and weatherhead also need replacing, and whether Seattle City Light has to upsize the service drop. We give every Seattle homeowner a flat-rate quote in writing after a metered assessment and a load calculation per NEC Article 220, so the number you see is the number you pay. We will not quote a sticker price before the load math, because that would be guessing.
