Panel Upgrades in McLean, VA
FPE, Zinsco, or 100-Amp Panel in McLean? Insurance-Required and Elective Replacements
Ahmad Shaban — Virginia-licensed Master Electrician — handles the full replacement: permit through Fairfax County, outdoor disconnect, surge protection, and Dominion coordination. Serving Langley, Salona, McLean Hamlet, Chesterbrook, and all McLean neighborhoods.
If your McLean home has a Federal Pacific or Zinsco panel, your insurer may already be requiring this
Federal Pacific Stab-Lok and Zinsco panels are documented fire risks — independent testing shows their breakers can fail to trip on overload. Most insurers now refuse to write or will cancel policies on homes with these panels. In McLean’s 1950s–1970s estate neighborhoods — Langley, Salona, McLean Hamlet — these panels are common.
If your insurer has flagged your panel, or a home-sale inspection identified an FPE or Zinsco unit, here is what it costs, what the process looks like, and why a code-complete replacement matters.
Call 571-500-6637 for a Same-Day AssessmentWhat a code-complete panel upgrade includes in McLean — and what drives the cost
A panel upgrade in McLean today is not the same scope it was five years ago. Under the 2020 NEC (in effect across Fairfax County via the 2021 Virginia USBC), a code-complete upgrade now includes:
- Outdoor emergency disconnect (NEC 230.85) — required on all one- and two-family dwelling service upgrades. This is a code-required addition, not an upsell.
- Whole-home surge protection (NEC 230.67) — required when the service or panel is replaced.
- Permit through Fairfax County LDS — McLean is unincorporated Fairfax County. EV pulls the ELER trade permit via the PLUS portal so you do not navigate it yourself.
- Dominion Energy meter-base coordination — the meter pull, service reconnection, and inspection scheduling are included.
If a quote you received does not include the outdoor disconnect or surge protector, it is either not code-complete or those items will appear as add-ons later. We include them in the written estimate upfront — no surprise line items.

Six signs your McLean panel needs replacement
Not every panel issue requires a full upgrade. These six triggers are the ones that consistently lead to a replacement scope — not a repair — in McLean homes.
McLean’s estate-era housing stock makes panels 1 and 4 especially common: FPE Stab-Lok panels in 1960s–70s Langley and Salona homes, and insurance renewals that flag them. If your home was built before 1980, start with the first two items on the right.
If none of these match, you may need troubleshooting rather than a panel replacement — the symptoms overlap, and we diagnose which scope you actually need before quoting.
Does your panel match any of these?
Each sign points to a common McLean housing scenario.
Federal Pacific Stab-Lok or Zinsco panel
Independent testing shows these breakers can fail to trip. Insurers refuse or cancel coverage. Extremely common in 1960s–1970s Langley, Salona, and McLean Hamlet estate homes.
Fuse box still in place
Some pre-1960s McLean properties still have fuse panels. A full conversion to a modern breaker panel with 200-amp service is the standard recommendation.
100-amp service with EV charger, central AC, or pool pump
A 100-amp panel sized for mid-century loads cannot support today’s combined draws. McLean estate homes with pools, EV chargers, and multiple HVAC zones are the most common upgrade candidates.
Insurance renewal requiring panel upgrade
The insurer flags the panel brand (FPE/Zinsco) or age. The replacement clears the underwriting requirement. We provide the documentation your insurer needs.
Pre-sale inspection flagging the panel
Home inspectors in McLean routinely flag FPE, Zinsco, and undersized panels. A code-complete replacement before listing removes the buyer objection.
Finished basement or detached structure added since the panel was installed
Langley and Salona estate lots often have pool houses, guest houses, or finished garages that were added decades after the original panel. The added load may exceed the original service.
Why McLean homes need panel upgrades — by era
McLean’s housing is more architecturally diverse than most Northern Virginia suburbs. Three distinct eras of construction create three different panel scenarios — knowing yours tells you what to expect before the assessment.
1950s–1970s estate-era homes
Langley, Salona, McLean Hamlet, parts of ChesterbrookLarge lots (quarter-acre and up), original 100-amp panels sized for a mid-century load profile. FPE Stab-Lok and Zinsco panels are common in this era — both are now known fire risks and trigger insurance denial or cancellation at many carriers.
Today’s combined load — Level 2 EV charger, pool pump, whole-home HVAC, smart-home devices, multiple large-appliance circuits — overwhelms a panel that was designed for a refrigerator, a window unit, and an electric range. Insurance pressure is the number-one non-emergency reason McLean estate owners call for a panel upgrade.
1970s–1990s colonials
Franklin Park, El Nido, parts of Chesterbrook200-amp service was standard by this era, but mid-1970s aluminum branch wiring and pre-1996 GFCI gaps remain common. The panel itself is usually adequate — the branch circuits and connections are where failures appear.
Symptoms: intermittent power loss to one room, GFCI nuisance trips on bathroom circuits, aging junction-box splices in finished basements. If the panel brand is sound and the service is 200A, the scope is often a diagnostic and targeted repair, not a full panel replacement.
2000s–2020s luxury builds and infill
Langley/McLean proper infill, Lewinsville areaModern 200A (or 400A) service with AFCI breakers that are sensitive by design. Failure modes: nuisance AFCI trips from smart-home miswiring by prior owners, bonded-neutral errors from DIY device installs, and EV-charger circuits that were installed without a load calculation.
This profile skews toward troubleshooting and EV-charger sub-panel calls, not full panel replacement. We diagnose whether the issue is the panel or the branch wiring before recommending a scope.
Eight panel scenarios we see in McLean
Each scenario describes a real scope of work. The neighborhoods named are where we see each one most often — your home may not be in that neighborhood and still have the same issue.
100A → 200A estate upgrade
Langley, Salona — original 100-amp panels on large-lot homes with modern load demands. Full service upgrade with NEC 230.85 outdoor disconnect and NEC 230.67 surge protection. See the full panel upgrade process.
FPE Stab-Lok replacement
Langley, McLean Hamlet — insurer flagged the panel. We remove the FPE unit, install a modern 200A panel with all code-required adders, and provide documentation for your insurance carrier.
Zinsco replacement
Same 1960s–70s era stock as FPE. Zinsco breakers can fuse to the bus and fail to trip — same insurance pressure, same replacement scope. Often confused with FPE; both require full replacement.
Fuse box → breaker conversion
McLean Hamlet, older Chesterbrook — pre-1960s homes still on fuse panels. Full service conversion: new 200A breaker panel, Dominion meter-base coordination, County ELER permit.
EV charger prep (Level 2 circuit)
McLean proper, Langley — the panel has no headroom for a 40A or 50A continuous-draw circuit. Load calculation first, then dedicated circuit or sub-panel install.
Sub-panel for detached structure
Langley, Salona estate lots — pool houses, guest structures, and detached garages that need their own sub-panel fed from the main. Requires a load calculation and its own ELER permit.
Pre-sale inspection remediation
All McLean neighborhoods — the home inspector flags the panel brand, age, or capacity. A code-complete replacement before listing removes the buyer objection and keeps the sale timeline on track.
Service mast replacement
Estate-era homes where the overhead service mast is aged or damaged. Coordinated with Dominion for the meter pull and reconnection. Often paired with a panel upgrade.
Equipment issues that drive McLean panel replacements
Four named equipment scenarios appear repeatedly in McLean service calls. Each has its own risk profile and replacement scope.
Federal Pacific (FPE) Stab-Lok
Documented fire riskIndependent testing shows FPE breakers can fail to trip on overload. Insurers refuse to write or cancel policies on homes with these panels. Extremely common in 1960s–70s Langley, Salona, and McLean Hamlet estate stock — this is the most frequent insurance-trigger scenario for McLean panel calls.

Zinsco panels
Documented fire riskZinsco breakers can fuse to the bus bar and not trip — a different failure mode from FPE but the same outcome: the breaker does not protect the circuit. Same insurer refusal pattern. Appears in the same 1960s–70s McLean era. Often confused with FPE; both require full replacement, not repair.
Aluminum branch wiring
Connection hazardMid-1970s aluminum branch wiring appears in Franklin Park, El Nido, and parts of Chesterbrook. The wiring itself is not the problem — the terminations at outlets and switches overheat without CO/ALR-rated devices. CO/ALR pigtailing is the standard remediation; a full rewire is a larger scope that Ahmad can quote on-site.
AFCI nuisance trips
Diagnostic required2000s and later McLean proper infill and Lewinsville area builds use AFCI breakers that are sensitive by design. Smart-home devices add harmonics that can trip AFCI breakers. We diagnose whether the trip is a genuine arc fault or a nuisance before recommending replacement — an unnecessary panel swap is the wrong answer here.
Permits and code in McLean — one authority, one process
McLean is unincorporated Fairfax County — not a city and not a town. There is no separate Town of McLean permitting layer (unlike Vienna or Falls Church). All permits go through one office.
Fairfax County Land Development Services (LDS)
The single permit authority for all McLean residential electrical work.
- Phone: 703-222-0801
- Office: 12055 Government Center Pkwy, Fairfax, VA 22035
- Online: PLUS portal (plus.fairfaxcounty.gov)
- Electrical = ELER trade permit — no plans required for standard residential work; pulled online
Code now in effect
Virginia is on the 2021 USBC incorporating the 2020 NEC, in effect across all of Fairfax County including McLean.
- NEC 230.85 — outdoor emergency disconnect required on one- and two-family dwelling service upgrades
- NEC 230.67 — whole-home surge protection required when the service/panel is replaced
- Service work ≥600 amps requires a signed service riser diagram from a Virginia Master Electrician — Ahmad qualifies
EV pulls the permit for you. The County recommends a licensed contractor pull the permit so they can enforce compliance. We file through the PLUS portal, schedule the inspection, and coordinate with Dominion — you do not navigate the permitting system yourself. McLean ZIPs 22101, 22102, and 22106 are geographic references only — they do not determine your permit authority. All McLean parcels permit through Fairfax County LDS.
What is included in the estimate — and what lowball quotes leave out
A written estimate from EV Electric for a McLean panel upgrade itemizes the full code-complete scope. Here is what a credible estimate includes — and what to look for if another quote seems significantly lower.
- 100A → 200A full service upgrade. Panel, meter base, service entrance conductors, outdoor emergency disconnect (NEC 230.85), whole-home surge protector (NEC 230.67). All code-required — not optional add-ons.
- FPE / Zinsco panel swap (same amperage). If your service is already 200A and only the panel brand is the issue, the scope is smaller: new panel, breaker reorganization, surge protector, permit. No new service entrance or disconnect required if the service is not being upgraded.
- Sub-panel for detached structure. A separate 60A–100A sub-panel for a pool house, guest structure, or detached garage. Requires its own load calculation and ELER permit.
- Permit, inspection, and Dominion coordination. Included in every panel upgrade estimate — not a separate line item and not billed after the fact.
Our process — quick version
You call → we schedule an on-site load assessment at your McLean home → Ahmad inspects the panel, measures the load, and gives you a written estimate → you approve → we pull the Fairfax County ELER permit → installation day (typically one full day for a standard 200A upgrade) → County inspection → Dominion restores the meter. Written estimate before any work starts — no surprises.

Frequently asked questions — panel upgrades in McLean
How much should an electrical panel upgrade cost?
A code-complete panel upgrade in McLean includes the panel, outdoor emergency disconnect (NEC 230.85), whole-home surge protection (NEC 230.67), permit, inspection, and Dominion coordination. The range depends on your service amperage and panel condition. Call 571-500-6637 for a free on-site assessment and written estimate.
How much does it cost to upgrade from 100 amp to 200 amp?
A 100-to-200-amp service upgrade is the most common scope in McLean’s 1950s–70s estate neighborhoods. The cost includes the panel, new service entrance conductors, outdoor disconnect, surge protector, permit, and Dominion meter-base coordination. We provide a written estimate specific to your home after an on-site assessment.
Can I upgrade my electrical panel without rewiring my house?
In most cases, yes. A panel upgrade replaces the panel and service entrance — it does not require rewiring the branch circuits throughout the house. The existing branch wiring connects to the new panel. If the branch wiring has a separate issue (aluminum wiring, damaged insulation), that is a different scope we identify during the assessment.
Is upgrading your electrical panel worth it?
If your insurer is requiring it (FPE or Zinsco), it is not optional — the alternative is losing coverage. If your panel is undersized for your current loads (EV charger, central AC, pool pump), an upgrade prevents chronic tripping and potential fire risk. If you are selling, it removes a common buyer objection.
Does McLean require a permit for a panel upgrade?
Yes. McLean is unincorporated Fairfax County — all electrical panel work requires an ELER trade permit through Fairfax County Land Development Services. EV Electric pulls the permit through the PLUS portal, schedules the inspection, and coordinates with Dominion. You do not navigate the permit system yourself.
Why won’t my insurer cover a Federal Pacific panel?
Independent testing has shown that FPE Stab-Lok breakers can fail to trip on overload — meaning they may not protect the circuit during a fault. Most insurers now consider FPE panels a documented fire risk and refuse to write or renew policies on homes with them. Replacing the panel with a modern unit clears the underwriting requirement.
How long does a panel upgrade take?
A standard 200-amp panel upgrade in McLean typically takes one full day of on-site work. The Fairfax County inspection is scheduled after installation — usually within a few business days. Dominion meter restoration is coordinated on the same timeline. The total process from assessment to completion is typically one to two weeks.
What is the difference between a panel upgrade and a service upgrade?
A panel upgrade replaces the breaker panel inside the house. A service upgrade replaces the panel plus the service entrance conductors, meter base, and weatherhead — everything from the utility connection to the panel. A 100-to-200-amp upgrade is a service upgrade; an FPE-to-modern swap at the same amperage is a panel upgrade. We determine which you need during the on-site assessment.
