Panel Upgrade in Bethesda, MD
200-Amp Panel Upgrades in Bethesda, MD — Code-Compliant, Permitted Through Montgomery County
Ahmad Shaban — Virginia-licensed Master Electrician — assesses your panel on-site, gives you a written estimate that spells out every code-required item, and pulls the correct permit through Montgomery County’s Department of Permitting Services. Based at 9488 Fairfax Blvd in Fairfax, VA — a short Beltway drive to Bethesda, Chevy Chase, and Potomac.
What drives the cost of a panel upgrade in Bethesda — and what’s included
The most common question Bethesda homeowners ask before scheduling an estimate: “How much does a 200-amp panel upgrade cost?” The honest answer is that the total depends on what a code-complete job requires at your specific home — and Bethesda’s housing stock ranges from 1920s Kenwood colonials to 2020s Downtown Bethesda infill, each with different starting points. We give you a written estimate before any work starts, itemized so you can see exactly what you’re paying for.
Cost drivers — what shapes the estimate in Bethesda
- Panel size (amps). The most common upgrade in Bethesda is 100-amp service to 200-amp. Bethesda’s pre-war homes in Kenwood and Alta Vista may still have 60-amp fuse boxes — a larger scope than a straightforward 100-to-200 swap. If your home already has 200-amp service but the panel itself is an FPE, Zinsco, or aging model, the scope changes: it’s a panel replacement, not a service upgrade.
- Code-required additions. Montgomery County follows the National Electrical Code (NEC). The specific NEC edition currently enforced by the county determines which code additions apply to your panel upgrade. Contact the Montgomery County Department of Permitting Services (DPS) at 240-777-0311 to confirm current requirements for your project. Any quote that doesn’t account for the current code is incomplete — and the inspection will catch it.
- Permit and inspection fees. A permit is required for every panel upgrade in Bethesda. Montgomery County DPS handles all electrical permits in Bethesda — unlike Fairfax, VA, where there are two jurisdictions to navigate. We pull the permit for you; the cost is part of the written estimate, not a surprise add-on.
- Utility coordination (Pepco). Bethesda is served by Pepco (Potomac Electric Power) — not Dominion Energy, which serves Virginia. A full service upgrade requires Pepco to disconnect and reconnect the meter. The coordination timeline affects scheduling — we handle the call to Pepco and sequence the work around their slot.
- Home age and access. A 1930s Kenwood colonial with original knob-and-tube remnants is a fundamentally different job than a 2010s Woodmont Triangle townhouse. Older Bethesda homes may need the meter base replaced alongside the panel; finished basement ceilings in Bradley Hills split-levels add labor to run new conduit. The on-site estimate accounts for the actual work — not a generic quote.
- Service mast condition. If the overhead service mast (the conduit running from the weatherhead to the meter) is deteriorated — common in Bethesda homes built before 1960 — the code may require replacing it as part of the service upgrade. We include this in the estimate if it applies.
What’s included in every EV Electric panel upgrade estimate
- On-site load assessment. We calculate the actual electrical load your Bethesda home draws before specifying panel size. A 200-amp panel that’s undersized for your combination of central AC, EV charging, and modern kitchen appliances is still undersized — we size it right the first time.
- All code-required additions per the NEC edition enforced by Montgomery County. Whatever the current code requires for your panel upgrade, it’s included in the estimate — not an optional line item. The permit inspection will check for compliance; we build the job to pass.
- Permit pulled on your behalf through Montgomery County DPS. We file through the county’s eServices portal or in person at the DPS office. The permit cost is part of the written estimate.
- Inspection scheduling and coordination. We schedule the electrical inspection with Montgomery County and are on-site when the inspector arrives.
- Pepco coordination. We contact Pepco to arrange meter disconnect and reconnect. No additional charge for coordination.
- Written, itemized estimate before any work starts. The estimate is firm — what we quote is what you pay. No “time and materials” billing on panel work. Call 571-500-6637 to schedule the on-site assessment.
Did your insurer flag your Federal Pacific or Zinsco panel? Here’s why — and what Bethesda homeowners should do
Insurance pressure is the single most common reason Bethesda homeowners call us for a panel upgrade outside of an active failure. If your home insurer has sent a letter requiring panel replacement, or if a home inspector flagged the panel during a sale, here’s what’s behind it:
- Federal Pacific Electric (FPE) Stab-Lok panels — independent testing shows that FPE Stab-Lok breakers can fail to trip on overload, allowing a circuit to carry current beyond its rated capacity. This is a documented fire risk. FPE breakers are common in Bethesda’s mid-century homes — particularly Burning Tree, Westgate, and Bradley Hills neighborhoods built in the 1950s through 1970s. Most insurers now refuse to write new policies or will decline to renew existing policies on homes with these panels.
- Zinsco panels — Zinsco breakers can fuse to the bus bar and physically fail to trip, leaving the circuit energized during an overload. Same insurance outcome: most carriers treat them as uninsurable without replacement.
- Fuse boxes in pre-war Bethesda homes — Kenwood, Alta Vista, Battery Park, and Edgemoor have some of the oldest residential housing in the greater DC metro area. Original 60-amp fuse boxes can’t safely carry modern loads, can’t accept AFCI/GFCI breakers, and most insurers now require conversion to a breaker panel.
- What the insurance letter means: the carrier has identified your panel as a known-hazard product. Their deadline is a real deadline — if the panel isn’t replaced by the date specified, coverage lapses. We can typically schedule and complete the replacement within the insurer’s window. Call early rather than close to the deadline — Pepco coordination is the scheduling variable we can’t fully control.
We replace FPE Stab-Lok and Zinsco panels with new 200-amp code-compliant service, permitted through Montgomery County DPS and coordinated with Pepco.
6 signs your Bethesda home needs a panel upgrade
Most panel issues don’t announce themselves with a fire — they show up as recurring nuisances that homeowners learn to work around. These are the real signals that the panel is the bottleneck, not the appliance or the circuit. Bethesda’s housing stock spans a century, and the failure modes vary by era.
Signs you need a panel upgrade
Expand each sign for what it means and what to do.
You still have a fuse box (not breakers)
Fuse boxes were standard through the 1950s and are found in Bethesda’s oldest neighborhoods — Kenwood, Alta Vista, Edgemoor, and Glen Echo Heights homes built in the 1920s through 1950s. They can’t safely carry modern electrical loads, can’t accept AFCI/GFCI breakers, and most insurers require replacement. A fuse-to-breaker conversion is the correct fix — not just swapping fuses for larger ones, which creates a fire hazard.
You have a Federal Pacific (FPE) or Zinsco panel
Both brands have documented breaker-failure modes (see the insurance section above). If you don’t know your panel brand, open the door: Stab-Lok is printed on FPE breakers; Zinsco panels typically have teal or gray breakers with the Zinsco or GTE-Sylvania label. These panels appear in Bethesda’s Burning Tree, Westgate, and Bradley Hills homes from the 1950s–1970s. Call us — we’ll confirm the brand on-site and provide a written replacement estimate.
Your breakers trip regularly under normal load
A circuit that trips repeatedly when you run the dishwasher and the microwave at the same time isn’t a “bad breaker” — it’s a sign the circuit can’t carry the demand. In a 100-amp panel, this happens because the total service capacity was designed for mid-century appliance loads. Bethesda’s summer AC demand on Pepco’s grid makes this worse — compressor inrush on an already-maxed 100A panel causes flicker and trips. A diagnostic visit determines whether the fix is a dedicated circuit or a full panel upgrade.
Your insurer has flagged the panel or required replacement
If you’ve received a letter from your homeowner’s insurance carrier requiring panel replacement within a set deadline, treat it as urgent. Coverage lapses if the deadline passes without completed work. We can typically complete the replacement before most insurer deadlines — call us with your letter in hand so we can assess the timeline. We pull the permit through Montgomery County DPS and coordinate with Pepco.
You’re adding an EV charger, major appliance, or home addition
A Level 2 EV charger requires a dedicated 240V, 50-amp circuit. Central AC, an induction range, a tankless water heater, and an EV charger running simultaneously can exceed what a 100-amp panel can deliver. Many Bethesda homeowners adding chargers for their daily commute into DC discover their mid-century panel can’t support the additional load. We calculate the actual load before specifying a panel size.
You’re selling your home and the inspector flagged the panel
Home inspectors flag FPE, Zinsco, fuse boxes, and double-tapped breakers as defects. In Bethesda’s competitive real estate market, buyers’ agents routinely ask for panel replacement as a contract condition. We provide a written estimate quickly for disclosure purposes and schedule the work to meet contract deadlines. An upgraded, permitted panel — with the Montgomery County permit card and inspection certificate — is documented value that belongs in the listing.
Panel upgrade scenarios — what each job involves in Bethesda
Not every panel job is the same. The eight most common scenarios in Bethesda, and what each one requires:
100-amp to 200-amp service upgrade
The most common upgrade in Bethesda’s mid-century homes — Burning Tree, Westgate, Westbard, and Bradley Hills. Replaces the panel, meter base (if needed), and service entrance conductors. Requires Pepco disconnect/reconnect, a Montgomery County DPS permit, and compliance with the NEC edition currently enforced by the county.
FPE Stab-Lok replacement
Remove the entire FPE panel and bus — not just swap breakers. FPE parts are discontinued; compatible replacements don’t exist. The job installs a new 200-amp panel with current-code breakers and all code-required additions. Insurance-driven timeline: we prioritize these calls for Bethesda homeowners facing coverage deadlines.
Zinsco panel replacement
Same scope as FPE: full panel swap. Zinsco breakers can’t be safely reused or replaced in kind. New 200-amp service with all NEC code requirements. Zinsco panels appear in Bethesda homes built in the late 1960s through early 1970s, particularly in Westgate and parts of Westbard.
Fuse box to breaker panel conversion
A stronger need in Bethesda than in most Northern Virginia cities — Bethesda’s pre-war housing stock in Kenwood, Alta Vista, Battery Park, and Edgemoor means more original fuse boxes still in service. The conversion replaces the fused service with a modern breaker panel, adds AFCI/GFCI breaker capability, and brings the service entrance up to current code. A common pre-sale upgrade in Bethesda’s real estate market.
EV-charger panel prep
A Level 2 charger at 40-50 amps is a continuous load — the NEC requires the circuit to be rated for 125% of continuous load. If the existing panel can’t add a 50-amp breaker without exceeding its capacity, the panel gets upgraded before the charger circuit is run. Common in Bethesda where EV ownership rates are among the highest in the DC metro. See also: EV charger installation in Bethesda.
Sub-panel installation
A detached garage, finished basement, in-law suite, or home office addition often needs its own sub-panel fed from the main. We size the feeder conductors to the sub-panel load, install the sub-panel, and route circuits. Montgomery County DPS permit required; we pull it for you.
Pre-sale panel upgrade
Bethesda sellers who want to remove a known defect from the inspection report before listing. We provide a written estimate quickly for disclosure, complete the work under permit through Montgomery County DPS, and provide the permit card and inspection certificate — documentation that transfers to the buyer and belongs in the listing.
Service mast replacement
The overhead service mast (weatherhead, conduit, and service entrance conductors from the Pepco drop to the meter) deteriorates over decades. Bethesda’s pre-war homes with original service masts are the most common candidates. A corroded or damaged mast is a Pepco disconnection risk and a code defect during inspection. Often paired with a panel upgrade; can also be standalone.
Why Bethesda homes need panel upgrades — by era
Bethesda’s housing stock spans over 80 years of electrical code and construction practice. The era your home was built tells you what panel risk profile to expect before we even open the door.
Pre-war & early postwar (1920s–1950s)
Kenwood, Battery Park, Alta Vista, Edgemoor, Glen Echo Heights, WoodhavenSome of the oldest homes in the entire service area. Original 60-100-amp panels — and some still have fuse boxes. The oldest homes from the 1920s-1930s may have remnants of knob-and-tube wiring. Insurance carriers pressure homeowners with fuse boxes and ungrounded systems to upgrade. Kenwood’s large 1930s-40s colonials and Battery Park’s mid-century bungalows are prime territory for fuse-box-to-breaker conversions and 100-to-200-amp upgrades.
Panel risk: Fuse box replacement, 60/100-to-200A upgrade, service mast replacement on original pre-war utility drops, potential knob-and-tube remediation at the panel.
Mid-century (1950s–1970s)
Burning Tree, Westgate, Westbard, Bradley HillsClassic 100-amp panels sized for mid-century electrical loads — no central AC, no EV charger, no induction range. Federal Pacific (FPE) Stab-Lok panels appear heavily in this era, and Zinsco panels in the later years. Mid-1970s builds in Bradley Hills also introduced aluminum branch wiring, which requires attention at panel terminations. Failure modes: persistent trips when running the AC compressor, warm outlets, dimming on large-appliance start.
Panel risk: FPE/Zinsco replacement, 100-to-200A upgrade for modern loads, aluminum branch wiring remediation at terminations.
Infill & modern (2000s–2020s)
Downtown Bethesda, Woodmont Triangle, newer teardown-rebuilds throughout200-amp service, AFCI breakers, modern loads. These homes start current — but they weren’t necessarily built for the loads homeowners are adding now. EV-charger capacity questions are the most common call from newer Bethesda homes. AFCI nuisance trips from smart-home devices and miswiring by the prior owner’s contractor are the second. Sub-panel additions for basement conversions and home offices round out the list.
Panel risk: EV-readiness assessment, sub-panel addition for additions/garages, AFCI nuisance-trip diagnosis.
If your Bethesda home falls in any of these eras, the on-site assessment tells you whether your panel is current, approaching end-of-life, or an active insurance risk. The assessment is free — call 571-500-6637 to schedule it.
Permits & code in Bethesda — this is Maryland, not Virginia
Bethesda is in Montgomery County, Maryland — a different state, a different permit authority, and potentially different electrical code requirements from every Virginia page on our site. If you’re comparing quotes from a NoVA-based electrician who also serves Bethesda, this section tells you what to verify.
Montgomery County Department of Permitting Services (DPS)
All electrical permits in Bethesda go through a single authority: the Montgomery County Department of Permitting Services (DPS). Unlike Fairfax, VA — where the City and County are separate jurisdictions with separate permit offices — Montgomery County is the sole permit authority for all of Bethesda, Chevy Chase, Potomac, and Rockville.
- Phone: 240-777-0311 (MC311)
- Email: DPS.electrical-mechanical@montgomerycountymd.gov
- Hours: Mon-Fri, 7:30 AM – 4:00 PM
- Online: eServices portal (permittingservices.montgomerycountymd.gov)
- ePlans available for electronic plan submission
We pull the permit through Montgomery County DPS for every panel upgrade in Bethesda. The permit cost is included in the written estimate — not a separate line item after the fact.
Maryland electrical code — what you should know: Montgomery County follows a version of the National Electrical Code (NEC). The specific edition currently enforced by the county determines what code additions apply to your panel upgrade. We recommend contacting DPS at 240-777-0311 to confirm current requirements for your project. This is a material difference from Virginia, where the 2021 Uniform Statewide Building Code (incorporating the 2020 NEC) is clearly documented. Any electrician quoting you a panel job in Bethesda should be able to tell you which NEC edition Montgomery County enforces — if they can’t, that’s a red flag about their familiarity with the MD regulatory environment.
Licensing — Virginia-licensed Master Electrician serving Maryland
Ahmad Shaban holds a Master Electrician license issued by the Commonwealth of Virginia — the state’s highest electrician credential. Virginia and Maryland have a reciprocal licensing agreement for master electricians: a Virginia-licensed master electrician whose license was obtained by exam can apply for a Maryland reciprocal master license through the Maryland State Board of Electricians without retaking the MD exam. Ahmad’s Virginia license qualifies for this reciprocal path.
The Master Electrician credential matters for panel work: it’s the license level required for signing service riser diagrams on larger installations, and it demonstrates the depth of examination and experience that separates a master from a journeyman.
Pepco — not Dominion
Bethesda is served by Pepco (Potomac Electric Power Company), not Dominion Energy, which serves our Virginia service area. A full service upgrade requires Pepco to disconnect and reconnect the meter. We coordinate with Pepco directly — the timeline and process differ from Dominion’s. Storm-restoration open-neutrals after summer thunderstorms are a Pepco-specific pattern that Bethesda homeowners should be aware of: a voltage spike during restoration can damage appliances and electronics. A whole-home surge protector at the panel — which we include per code requirements — protects against exactly this scenario.
Equipment deep-dives — what’s in your Bethesda panel and why it matters
Four equipment types account for most panel upgrade calls in Bethesda. Here’s what each one is, what the risk is, and what the remediation involves.
Federal Pacific Electric (FPE) Stab-Lok
Insurance Risk · Fire HazardFPE Stab-Lok breakers were installed in millions of homes built between the 1950s and 1980s. Independent testing — including a Consumer Product Safety Commission-funded study — found that Stab-Lok breakers can fail to trip on overload at a significantly higher rate than listed breakers. A breaker that doesn’t trip allows the circuit to carry current beyond its rated capacity, potentially igniting insulation.
FPE panels appear in Bethesda’s Burning Tree, Westgate, and Westbard neighborhoods — the 1950s-1970s building wave. Replacement means removing the entire panel and bus. FPE replacement parts were discontinued; there is no safe retrofit. The replacement is a new 200-amp panel with current-code breakers, permitted through Montgomery County DPS.
Zinsco (and GTE-Sylvania)
Insurance Risk · Fire HazardZinsco breakers can fuse to the bus bar over time, physically preventing them from tripping during an overload. A breaker welded to the bus cannot protect its circuit. Zinsco panels are found in Bethesda homes built in the late 1960s and early 1970s — Westgate and parts of Westbard are the most common areas.
Like FPE, the correct remediation is full panel replacement — not breaker swaps. GTE-Sylvania-branded panels use the same Zinsco design and carry the same risk. If you’re not sure which panel you have, the teal or gray breaker color and the Zinsco or GTE-Sylvania label are identifying markers we verify on-site.
Fuse boxes — a bigger factor in Bethesda than in NoVA
Insurance Risk · Capacity LimitBethesda has more pre-war homes with original fuse boxes than most Northern Virginia cities in our service area. Kenwood, Alta Vista, Battery Park, and Edgemoor all have homes from the 1920s-1940s that may still run on 60-amp fused service. Fuse boxes can’t safely carry modern electrical loads, can’t accept AFCI/GFCI breakers, and most insurers now require conversion to a breaker panel.
A fuse-box-to-breaker conversion replaces the entire fused service with a modern 200-amp breaker panel. This is the highest-scope upgrade we perform in Bethesda — and it’s more common here than in any of our Virginia service areas. The conversion is permitted through Montgomery County DPS.
Aluminum branch wiring
Termination Risk · Remediation RequiredAluminum branch wiring was used as a substitute for copper in homes built roughly 1965-1973, when copper prices spiked. Aluminum expands and contracts more than copper with temperature changes, which loosens terminations at outlets, switches, and fixtures over time. Loose aluminum-to-device connections are a documented fire risk.
Aluminum branch wiring appears in mid-1970s Bethesda homes — Bradley Hills and some late-era Westbard properties. Remediation options range from installing CO/ALR-rated devices to pigtailing with Ideal AlumiConn connectors. Full rewire is a separate scope — see whole-house rewire for that path.
How panel upgrade estimates work in Bethesda — what to expect
A panel upgrade is a project, not a service call. Here’s how the estimate process works and what you should ask any electrician before you book the job — especially when comparing a Virginia-based electrician with local Maryland competitors.
The on-site assessment
We come to your Bethesda home, open the panel, assess the service entrance, look at the meter base condition, check the service mast, and calculate the actual electrical load your home draws. We can’t give you an accurate estimate without seeing the physical work — and any electrician who quotes you a panel replacement without an on-site visit is guessing. The assessment is free and takes about 30 minutes.
What a written estimate must include
Ask any electrician you’re considering — whether they’re based in Maryland or Virginia — to itemize these items in writing before you agree to the job:
- Panel size (amps) and brand to be installed
- All code-required additions per the NEC edition enforced by Montgomery County
- Whether permit and inspection fees are included or billed separately
- Whether Pepco coordination is included
- Whether the meter base and service entrance conductors are included if replacement is needed
- Whether the service mast is included if it needs replacement
- Which NEC edition the contractor is building to — and whether they’ve confirmed that edition with Montgomery County DPS
If any of these items are “not included” or “billed separately,” the quoted number isn’t a complete price. A code-complete panel upgrade in Bethesda includes all of them. The permit inspection will flag missing items — and the homeowner, not the contractor, is the one left with an incomplete job.
The written estimate is firm
EV Electric’s estimates are fixed-price for the scope specified. We don’t use time-and-materials billing on panel work. If we find something unexpected on the day of the job — a deteriorated meter base we couldn’t see at the assessment, for example — we stop, explain what we found, and give you a written change order before we proceed. No surprise invoices after the work is done.
Call 571-500-6637 to schedule your free on-site panel assessment and written estimate in Bethesda.
How the job works — the short version
You call -> we schedule a free on-site assessment at your Bethesda home -> we present a written, itemized estimate -> you approve it -> we pull the permit through Montgomery County DPS, coordinate with Pepco, and schedule the install -> the inspection passes before we consider the job done. We’re on-site for the Montgomery County inspection.

Frequently asked questions — panel upgrades in Bethesda, MD
How much should a panel upgrade cost in Bethesda?
The cost of a code-complete panel upgrade in Bethesda depends on panel size, whether the meter base or service mast needs replacement, the scope of code-required additions under the NEC edition enforced by Montgomery County, and permit fees. Bethesda’s pre-war housing stock often means a larger scope than a straightforward panel swap — fuse-box-to-breaker conversions and deteriorated service masts add to the job. We give you a written, itemized estimate after a free on-site assessment so there are no surprises. Call 571-500-6637 to schedule yours.
Can I upgrade my electrical panel without rewiring my house?
Yes — a panel upgrade replaces the panel (and service, if you’re upgrading from 100 to 200 amps) without touching the branch wiring running to your outlets, switches, and fixtures. The existing branch wiring stays in the walls. The exception: if the diagnostic reveals a wiring problem — aluminum branch wiring with deteriorated terminations in Bradley Hills-era homes, damaged circuits, or unsafe splices — we’d recommend addressing those separately. Panel upgrade and whole-house rewire are distinct scopes of work.
Is upgrading your electrical panel worth it?
For most Bethesda homeowners, yes — and for more than one reason. A code-complete 200-amp panel resolves the most common insurance flags (FPE, Zinsco, fuse box, undersized service), supports modern electrical loads (EV charger, central AC, induction range), and passes cleanly at a home inspection. In Bethesda’s competitive real estate market, a permitted panel replacement with the Montgomery County inspection certificate transfers as documented value to a buyer. Homes with FPE, Zinsco, or fuse-box panels face carrier cancellation risk — the upgrade removes that exposure.
Do I need a permit to upgrade my electrical panel in Bethesda?
Yes. A permit is required for every panel upgrade in Bethesda. Unlike Fairfax, VA — where there are two separate permit offices — Bethesda has a single permit authority: the Montgomery County Department of Permitting Services (DPS). You can reach DPS at 240-777-0311 or through their eServices portal online. EV Electric pulls the permit for you and files with DPS directly. The permit fee is part of the written estimate.
My insurance company is requiring me to replace my FPE panel — how soon can you do it?
We prioritize insurance-deadline panel replacements. Call 571-500-6637 with your insurer’s letter in hand — we’ll schedule the on-site assessment quickly, turn around the written estimate, and confirm whether we can complete the work before your deadline. Most FPE and Zinsco replacements in Bethesda are completed within 1-2 weeks of estimate approval, depending on Pepco’s disconnect/reconnect scheduling. Don’t wait until close to the deadline — the Pepco coordination is the variable we can’t fully control.
Is EV Electric licensed to work in Maryland?
Ahmad Shaban holds a Virginia-licensed Master Electrician credential — the state’s highest electrician license, obtained by examination. Virginia and Maryland have a reciprocal licensing agreement for master electricians: a VA-licensed master electrician can apply for a Maryland reciprocal master license through the Maryland State Board of Electricians without retaking the MD exam. Ahmad’s Virginia license qualifies for this reciprocal path. The Master Electrician credential is the license level required to sign service riser diagrams for larger installations.
Will my power be off all day during a panel upgrade?
The main service is off for the portion of the job that requires working on the panel and service entrance — typically several hours. We coordinate with Pepco to minimize the outage window and aim to complete the work and restore service the same day. We’ll tell you the expected outage window when we schedule the job so you can plan accordingly. Pepco’s disconnect/reconnect scheduling is the main variable — we coordinate directly with them to lock in the timing.
What’s the difference between a panel upgrade and a service upgrade?
A panel upgrade replaces the breaker panel inside your home. A service upgrade replaces the conductors running from Pepco’s power line to your meter and panel — the service entrance. When you upgrade from 100-amp to 200-amp service, you typically need both: a new 200-amp panel and the larger service entrance conductors and meter base. When you replace an FPE or Zinsco panel that already has 200-amp service, you may only need the panel itself. The on-site assessment determines which scope applies to your Bethesda home.
