Panel Upgrade in Gaithersburg, MD
Panel Upgrade, Sub-Panel, or Full Service Replacement? The Right Call for Your Gaithersburg Home
A 1970s Montgomery Village townhome on 100-amp service needs a different answer than a 2005 Kentlands house that already has 200 amps. Ahmad Shaban — Virginia-licensed Master Electrician — comes out, opens the panel, walks you through which path fits your situation, and hands you a written estimate before any work begins. Permit filed through Montgomery County DPS. Gaithersburg served from our Fairfax shop via I-270, about 30 minutes out.
What shapes the cost of a Gaithersburg panel job — and how to tell which job you actually need
The first question most Gaithersburg homeowners ask is about cost. The straightforward answer: it depends on what the load assessment uncovers inside your panel. A fuse-box-to-breaker conversion on a historic Olde Towne home is a fundamentally different scope than adding a sub-panel to a Kentlands garage. What we can explain right now is what goes into every code-compliant panel replacement in Montgomery County — because this is where low estimates from unlicensed outfits fall apart at inspection time.
What a code-compliant panel replacement includes in Montgomery County
Montgomery County follows the NEC edition currently enforced under the Maryland Building Performance Standards. The county may still enforce the 2017 NEC or may have adopted a newer edition — contact DPS at 240-777-0311 to confirm which edition applies to your project. If Montgomery County enforces a recent NEC edition, two provisions apply to panel replacements:
- Outdoor emergency disconnect: A lockable shutoff accessible to first responders, mounted outside near the meter. We include this in every estimate regardless of which NEC edition the county enforces — your panel is code-complete under either scenario.
- Whole-home surge protection: A Type 1 or Type 2 SPD installed at the service entrance. Same approach — included in every estimate so there are no compliance surprises at inspection.
- Permit and inspection: Filed through Montgomery County Department of Permitting Services (DPS). The county is the building authority for all Gaithersburg addresses.
We include the emergency disconnect, surge protection, permit, Pepco meter coordination, and final inspection in every panel estimate — whether the county requires each item or not, you get a code-complete panel. Free written estimate before any work starts.
Call 571-500-6637 for a Free EstimateOther factors that move the estimate
Beyond the baseline code requirements, these variables determine your final number:
- Service size: 100A to 200A vs. same-size swap. A 100-to-200-amp upgrade means replacing the meter base and service entrance conductors — more material, more Pepco coordination. A 200-amp panel swap (new cabinet, same service size) is a tighter job.
- Panel brand and condition. Federal Pacific Stab-Lok and Zinsco panels have heat-damaged terminations from decades of improper thermal cycling. Re-terminating every branch conductor takes longer than a standard swap. That time is in the estimate upfront — not tacked on after.
- Access and wiring age. A panel in an unfinished basement is straightforward. A panel behind drywall in a finished utility room adds access labor. Homes with knob-and-tube (Olde Towne) or aluminum branch wiring (late Montgomery Village builds) require careful termination work.
- Sub-panel vs. full upgrade. If the main panel has capacity headroom but you need circuits in a new area — garage, basement ADU, workshop — a sub-panel is often the right scope. Less disruption and a lower cost than a full service upgrade.
Call 571-500-6637 — Ahmad comes to the house, opens the panel, runs the load calculation, and hands you a written estimate on the spot. No trip fee and free estimates for Gaithersburg, Rockville, Germantown, or North Potomac panel assessments.
Six situations that tell you which upgrade path to take
Not every panel problem has the same solution. These six signals map directly to one of three paths — full service upgrade, panel replacement at the same amperage, or a sub-panel addition. Knowing which signal you are looking at saves you from overpaying for scope you do not need.
If your home shows more than one of these signals, the load calculation resolves which path takes priority. That assessment is part of the free estimate, so there is no charge to find out which path you need.
Three upgrade paths — and how to identify which one your Gaithersburg home needs
Most electrician websites default to selling the biggest job. Here is the honest breakdown Ahmad uses on every Gaithersburg panel assessment to match the scope to the actual need.
Full service entrance upgrade
The right call when: your home has a fuse box, the service entrance is undersized (60A or less), or the existing service mast and meter base are damaged or deteriorated. Common in Olde Towne historic-district homes from the 1800s through the 1920s.
- Replaces everything from the weatherhead down: mast, meter base, service entrance conductors, and panel cabinet
- Brings the home from pre-war fuse service to a modern 200A breaker panel
- Includes Pepco coordination for the meter disconnect and reconnection
- Montgomery County DPS permit and inspection required
This is the largest-scope panel job. If your Olde Towne home still has a fuse box, this is almost certainly the path.
100A to 200A panel upgrade
The right call when: the home is on 100-amp service and you are adding high-draw loads — EV charger, heat pump, induction range, finished basement — or the existing panel is a Federal Pacific, Zinsco, or otherwise at capacity. The bread-and-butter job for Montgomery Village, Quince Orchard, and Summit Hall homes.
- Replaces meter base, service entrance conductors, main breaker, and panel cabinet
- Doubles usable capacity and adds slots for future circuits
- Emergency disconnect and surge protection included in every estimate
- Pepco meter drop, Montgomery County DPS permit, and inspection all handled
- Typical install: one full day
If your Montgomery Village or Quince Orchard home is on original 1960s-1980s service, the load calculation will almost certainly confirm this path.
Sub-panel for a garage, basement, or ADU
The right call when: the main panel is a safe brand, the service is already 200A, and you need dedicated circuits in a new area — detached garage for an EV charger, basement accessory dwelling unit, or workshop. Common in Kentlands, Lakelands, and newer Crown-area homes.
- Feeder run from the main panel to a new sub-panel in the target area
- Sub-panel gets its own breakers for the new circuits
- No Pepco coordination needed — the meter stays, the service size stays
- Montgomery County DPS permit still required; inspection by county
A sub-panel is the cleanest answer when your home already has the amperage headroom but needs more circuits in a specific location. The load calculation confirms whether the main panel can carry the additional feeder.
Not sure which of the three paths applies? That is what the free on-site assessment is for. Ahmad opens the panel, runs the load calculation, and explains — in plain language — which answer fits your home and why. Call 571-500-6637 to schedule.
Eight panel situations Gaithersburg homeowners bring us — and the right path for each
Every panel call comes down to matching the situation to the correct scope. Here are the scenarios we see most often across Gaithersburg’s mixed housing stock.
Fuse box in an Olde Towne pre-1920s home
Fuses cannot carry modern loads, and the entire service entrance — mast, meter base, conductors — is typically undersized for today’s demand. Conversion means replacing the full service entrance plus the panel cabinet. This is the most comprehensive panel job, and it is the only safe path for homes still running on original fuse service. Montgomery County DPS permit and Pepco coordination required.
100A panel in a 1960s-80s Montgomery Village home
The highest-volume panel upgrade scenario in Gaithersburg. These planned-community homes were built when 100 amps was considered generous. Add a central AC upgrade, an EV charger, or a finished basement and the math no longer works. The load calculation confirms what is already obvious from the breaker count: a full 100-to-200A upgrade is the right move.
FPE Stab-Lok panel — insurance-driven replacement
Federal Pacific Stab-Lok breakers fail to trip in roughly 25 to 50 percent of independent overcurrent tests. The bus bar design is the root cause — individual breaker swaps do not fix it. Insurers know this and many will refuse coverage, surcharge, or cancel. Full cabinet replacement with a current-code panel. Common in Montgomery Village and Quince Orchard builds from the 1960s-70s.
Zinsco panel — breakers fused to the bus
Zinsco’s aluminum bus bars corrode at the breaker connection points, causing breakers to physically bond to the bus. When a fault occurs, the bonded breaker cannot open the circuit. Same replacement protocol as FPE — full cabinet swap with a UL-listed panel. Sometimes labeled “Sylvania” after the brand acquisition. Present in some late-1970s Gaithersburg builds.
200A panel, adding an EV charger in a Kentlands garage
A Level 2 EV charger draws 30 to 50 amps continuously. If your Kentlands or Lakelands home is on 200A service and the panel has available slots, a dedicated 60A circuit or a garage sub-panel handles the charger without touching the main service. The load calculation confirms whether the headroom is there. See adding an EV charger for the full process.
Finishing a basement with a kitchenette or ADU
A basement finish with a kitchenette, bathroom, and multiple circuits needs its own breaker panel — running individual feeds from the main panel is messy and harder to troubleshoot later. A sub-panel in the basement is the clean solution if the main panel has feeder capacity. Common scope for Kentlands, Crown, and newer Shady Grove homes adding rental income or in-law space.
Pre-sale panel upgrade — inspector flagged the brand
A home inspector called out an FPE, Zinsco, or fuse box and the buyer wants it resolved before closing. We have compressed the permit-to-inspection cycle to handle pre-sale timelines when the deadline is real. Written estimate on the first visit, permit filed the same week through Montgomery County DPS.
Service mast damage after a storm
Pepco will not reconnect a damaged service mast. A storm-damaged or corroded mast means the full service entrance needs replacement — weatherhead, mast, meter base, and often the panel cabinet itself. When the service entrance is already being replaced, upgrading to 200A at the same time is usually the right call. This is an urgent job — no power until the mast is repaired and Pepco signs off.
Gaithersburg’s housing stock by era — three decades, three different panel profiles
Gaithersburg’s residential development spans from the 1800s to the 2020s — far more varied than most Montgomery County cities. The era your home was built determines what kind of panel risk you are likely carrying and which of the three upgrade paths makes sense.
Historic era: 1800s through 1920s
Olde Towne Gaithersburg, Washington Grove — fuse-box territorySome of the oldest homes in our service area. Original fuse boxes or very early breaker panels are still in place in many of these properties. Knob-and-tube wiring is possible in unremodeled sections. The service entrance itself — mast, meter base, conductors — is almost always undersized for any modern load profile. Central AC, an EV charger, or a heat pump is not happening on a 60-amp fuse service.
Typical path: Full service entrance upgrade with fuse-to-breaker conversion. The entire electrical feed from Pepco’s drop to the panel cabinet gets replaced. This is the right answer for nearly every Olde Towne home that has not already been upgraded.
Planned-community era: 1960s through 1980s
Montgomery Village, Quince Orchard, Summit Hall, Shady Grove — 100-amp territoryThe largest share of Gaithersburg’s housing stock. Montgomery Village alone has thousands of homes built between 1966 and the early 1980s, most on 100-amp service. FPE Stab-Lok panels were a common builder choice in this era. Even homes with safe panel brands are running at or near capacity after decades of added loads — finished basements, AC upgrades, kitchen remodels, and now EV chargers.
Typical path: 100-to-200A full upgrade. This is the highest-volume panel job in Gaithersburg. If your Montgomery Village or Quince Orchard home is on original service, the load calculation will confirm what the breaker count already suggests.
New urbanism and modern: 1990s through 2020s
Kentlands, Lakelands, Crown, newer Shady Grove — 200-amp territoryAlready on 200-amp service from day one. The panel itself is rarely the bottleneck. What these homes need most often is a sub-panel addition for a detached garage EV charger, a basement ADU with its own circuits, or a dedicated workshop space. AFCI nuisance trips — treadmills, legacy dimmers, certain vacuum motors — are the most common service call from this generation of homes.
Typical path: Sub-panel addition for new areas, or circuit addition plus AFCI breaker diagnosis for nuisance-trip complaints. Full upgrades are rare in this era.
Your home’s decade narrows the likely scope — the on-site load calculation confirms the actual answer. Both are part of the free estimate visit.
Permits and code in Gaithersburg — Montgomery County DPS handles it all
Gaithersburg is in Montgomery County, Maryland. All residential electrical permits go through one authority — Montgomery County Department of Permitting Services (DPS). Here is the accurate picture of what that means for your panel job.
Montgomery County DPS: your electrical building official
For all Gaithersburg addresses — whether inside the City of Gaithersburg municipal limits or in unincorporated Montgomery County with a Gaithersburg mailing address — Montgomery County DPS is the electrical building official. The county issues the residential electrical permit and performs the inspection.
- Portal: Montgomery County eServices
- Phone: 240-777-0311
- Address: 2425 Reedie Dr, Wheaton, MD 20902
- Permit type: residential electrical
- Standard panel or sub-panel typically does not require engineered plans
EV Electric files the permit, schedules the inspection, and follows through to a passed final. You receive a copy of the signed inspection record for your files and your insurance carrier.
Maryland licensing and Pepco coordination
Maryland and Virginia have separate licensing structures. Ahmad Shaban holds a Virginia-issued Master Electrician license — the Commonwealth’s highest electrician credential. Maryland reciprocal licensing provisions may apply; contact Montgomery County DPS to confirm current contractor requirements for your project.
- Pepco is the electric utility serving Gaithersburg — not Dominion (which serves Virginia)
- Any panel replacement that involves a meter disconnect requires Pepco coordination for the service drop and reconnection
- Pepco’s process for contractor-initiated meter work is separate from the county permit — we handle both
The same panel job requires two parallel coordination tracks: county permit plus Pepco meter work. We manage both so neither falls through the cracks.
NEC edition in effect: Montgomery County follows the NEC edition currently enforced under the Maryland Building Performance Standards — the county may still enforce the 2017 NEC or may have adopted a newer edition. Contact DPS at 240-777-0311 to confirm. We include the outdoor emergency disconnect and whole-home surge protection in every estimate regardless, so your panel is code-complete under either scenario.
Panel brands and equipment issues common in Gaithersburg homes
Gaithersburg’s wide range of housing eras means four distinct equipment patterns show up repeatedly during panel assessments. Each one has a different scope and a different answer.
Federal Pacific (Stab-Lok)
Replace — no repair optionFPE Stab-Lok panels were installed widely in U.S. homes from the 1950s through the 1980s. Independent testing has documented failure-to-trip rates of 25 to 50 percent in overcurrent fault conditions. The failure mode: breaker contacts fuse to the bus bar through repeated thermal cycling, preventing the circuit from opening during a fault.
In Gaithersburg, FPE panels are concentrated in Montgomery Village and Quince Orchard homes built during the 1960s and 1970s. Insurers flag these panels routinely — many carriers will not write new coverage on a home with a Stab-Lok panel in service.
The answer: full cabinet replacement with a current-code panel (Eaton, Square D, or Siemens). No re-breaker option is accepted by insurance carriers for this brand.
Zinsco (also labeled Sylvania)
Replace — no repair optionZinsco panels were manufactured through the 1970s and sold under the Sylvania name after acquisition. The failure mode is bus bar corrosion: aluminum bus bars corrode at the breaker slot, causing the breaker to physically bond to the bus. When a fault occurs, the bonded breaker cannot open. Same fire-risk profile as FPE through a different mechanical pathway.
Less common than FPE in Gaithersburg but present in some late-1970s builds. Check the panel door — if it says “Zinsco” or “Sylvania” with the distinctive gold-and-orange coloring, replacement is the correct answer.
The answer: full cabinet replacement. Same protocol as FPE — replace, do not attempt to repair.
Fuse boxes (Olde Towne / Washington Grove)
Full conversion to breaker panelFuse boxes predate modern breakers entirely. They are an insurance flag, a home-inspection flag, and a functional limitation — you cannot safely serve modern loads through fuses sized for a 1920s electrical demand profile. A fuse-to-breaker conversion replaces the entire enclosure with a new breaker panel, typically at 200 amps.
In Gaithersburg, fuse boxes are concentrated in the Olde Towne historic district and parts of Washington Grove. These conversions almost always require a full service entrance replacement alongside the panel swap — the meter base and service conductors are undersized too.
The answer: full service entrance upgrade plus fuse-to-breaker conversion. One-day install in most cases once the Pepco coordination is scheduled.
Aluminum branch wiring (mid-1970s builds)
Remediation — connection upgrade at devicesAluminum branch circuit wiring was used extensively in residential construction from roughly 1965 to 1973 when copper prices spiked. Aluminum expands and contracts more than copper under thermal cycling, loosening connections at outlets and switches over time. Loose connections create resistance, resistance creates heat, and heat creates fire risk.
Present in late Montgomery Village builds and some Quince Orchard homes from the mid-1970s. The wiring itself is not inherently unsafe — the terminations at every device and junction box are the risk point. Remediation involves CO/ALR-rated devices and anti-oxidant compound at every connection.
The answer: a panel assessment determines whether the terminations at the panel are safe, and an outlet-by-outlet remediation addresses the branch circuit connections. We scope both in the estimate.
How our estimates work — scope first, then a firm number
We do not publish panel prices because the right price requires opening your actual panel, checking the service entrance, and running the load calculation — not guessing from a zip code. What we can tell you is exactly what every written estimate covers so you can compare quotes on equal terms.
- The on-site assessment is free. Ahmad or a member of his team comes to the house, opens the panel, checks the service entrance condition, and runs the load calculation. You get the written estimate before any work is scheduled. No charge for the visit in Gaithersburg, Rockville, Germantown, or North Potomac.
- Every estimate includes the disconnect and surge protection. Whether Montgomery County’s current code mandates them or not, we include the outdoor emergency disconnect and whole-home surge protection in every panel replacement estimate — your panel is code-complete under any scenario. If another estimate omits them, ask why.
- Permit fees, inspection fees, and Pepco coordination — included. We file the Montgomery County DPS permit. We schedule the Pepco meter work. We meet the inspector on-site. All of that is in the estimate, not invoiced separately at the end.
- Scope changes get a revised written estimate. If we open the wall and find something unexpected — damaged wiring, an undisclosed sub-panel, aluminum branch circuits requiring additional remediation — we stop, show you, and revise the written estimate before continuing. No surprises at closeout.
How a Gaithersburg panel upgrade works — the short version
You call. Ahmad comes out, opens the panel, runs the load calculation, and hands you a written estimate on site. You decide. We file the Montgomery County DPS permit and coordinate with Pepco for the meter work. Install day runs 6 to 10 hours with power off for most of the day. County inspection follows — typically same week or next. You get a labeled panel, signed inspection record, permit copy, and before-and-after photos. FPE, Zinsco, fuse-box conversions, and aluminum wiring remediation are itemized in the estimate with no surprises at close.
For the full step-by-step breakdown including what to expect on install day, see our electrical services overview.

Your electrician: Ahmad Shaban
Ahmad Shaban holds a Master Electrician license issued by the Commonwealth of Virginia — the state’s highest electrician credential, requiring years of journeyman experience and a passed state exam. He is the person who comes out for most panel assessments, runs the load calculation, and explains what you genuinely need versus what you can defer.
Panel upgrades are the work where credentials matter most. The job touches the service entrance, the meter, and every circuit in the house — and it gets inspected by Montgomery County DPS. Ahmad has been pulling permits, coordinating with utilities, and passing inspections across Northern Virginia and the DC metro region for years. He hands you the documentation when the job is done so the upgrade is on the record for your insurer, your buyer, or your lender.
EV Electric Services holds a 5.0-star average across 113 Google reviews — real, recent reviews from homeowners across the DC metro area.
Gaithersburg neighborhoods we serve
We cover all of Gaithersburg and surrounding Montgomery County communities. Montgomery Village and Quince Orchard lead in volume — those are the planned-community-era neighborhoods where 100-amp panel upgrades and FPE replacements are most common.

Frequently asked questions — Gaithersburg panel upgrades
How much should a panel upgrade cost in Gaithersburg?
We do not publish prices because the correct scope requires opening your actual panel, checking the service entrance, and running a load calculation. Every estimate we write includes the DPS permit, outdoor emergency disconnect, whole-home surge protection, and Pepco meter coordination — whether the county’s current code mandates each item or not, your panel is code-complete. The on-site assessment is free. Call 571-500-6637 to schedule.
Can I upgrade my electrical panel without rewiring my house?
In most cases, yes. A panel upgrade replaces the service entrance, meter base, and panel cabinet — the branch circuit wiring to your outlets, lights, and appliances stays in place. Exceptions: if the existing wiring is knob-and-tube (common in Olde Towne pre-1920s homes), some circuits may need to be replaced for safety. If the home has aluminum branch wiring (mid-1970s Montgomery Village builds), the terminations at every device need remediation even if the panel itself is replaced. Ahmad identifies both conditions during the free on-site assessment.
Do I need a full 200-amp upgrade, or would a sub-panel handle it?
It depends on your current service size and what you are adding. If your home is on 100A service, a full 200A upgrade is almost always the right path — sub-panels cannot create more amperage than the main service provides. If you are already on 200A and need circuits in a new area (garage, basement, ADU), a sub-panel is usually the correct and less disruptive answer. The load calculation tells you definitively. We run it on the free estimate visit.
Is upgrading your electrical panel worth it?
If your panel is a Federal Pacific, Zinsco, or a fuse box, upgrading is a safety imperative — not a value question. Beyond the safety cases: a panel upgrade enables the modern loads that older panels cannot support (EV charger, heat pump, induction range, finished basement), removes a common insurance obstacle, and resolves a home-inspection flag that can hold up a sale or refinance. The cost of the upgrade is almost always less than the cost of deferring it through insurance surcharges, lost sale negotiations, and working around capacity limits.
How much does it cost to upgrade from 100 amps to 200 amps?
The number depends on the specific conditions at your home — panel location, service entrance condition, wiring age, and whether the meter base and weatherhead also need replacement. We do not quote over the phone because guessing at scope is how estimates go wrong. The on-site assessment is free, the written estimate is firm, and it includes the emergency disconnect, surge protection, DPS permit, and Pepco coordination regardless of which NEC edition the county enforces. Call 571-500-6637 to schedule.
Do I need a permit for a panel upgrade in Gaithersburg?
Yes. Montgomery County Department of Permitting Services (DPS) is the electrical building official for all Gaithersburg addresses. A residential electrical permit is required for any panel replacement or service upgrade. The permit is filed through the county eServices portal. EV Electric handles the permit filing, schedules the inspection, and follows through to a passed final — you receive a copy of the signed inspection record for your files.
Will my insurance company cancel my policy over a Federal Pacific panel?
Many carriers will — or they will surcharge, refuse to renew, or decline new coverage. Federal Pacific Stab-Lok breakers have documented failure-to-trip rates in fault conditions. Insurers treat FPE panels as a known fire risk. If your carrier sent a letter or your home inspector flagged the brand, the timeline is real. A typical FPE replacement runs about 7 to 10 business days from first call to passed inspection — if you call before the deadline, there is usually time. Call 571-500-6637.
What is the difference between Pepco and Dominion for panel work?
Pepco serves Gaithersburg and most of Montgomery County, Maryland. Dominion Energy serves Virginia. The distinction matters because utility coordination — meter drops, service reconnection, contractor pull numbers — follows each utility’s own process. We work with both. For your Gaithersburg panel job, all utility coordination is through Pepco. We handle the scheduling and paperwork.
Which path is right for your Gaithersburg home?
Free on-site load assessment. Written estimate before any work starts. Montgomery County DPS permit and Pepco coordination handled for you.
