If lights dim, breakers trip, or you are planning an EV charger or heat pump, it may be time to upgrade from 100 amp to 200 amp service. This guide explains when an upgrade makes sense, what is involved, and how Lloyd completes code‑compliant panel and service upgrades across Burlington, Montpelier, and nearby towns. You will see the real safety and capacity gains, clear pricing drivers, and how to schedule with confidence.
Why Homeowners Upgrade From 100 Amp To 200 Amp Service
Most Vermont homes built before the 1990s were designed around smaller electrical loads. Today’s homes power heat pumps, EV chargers, hot tubs, home offices, and more. A 200 amp service provides more headroom for these modern loads and improves safety when paired with updated protective devices.
Common reasons to upgrade:
- Frequent breaker trips or lights dimming when large appliances start.
- Plans for EV charging, heat pumps, hot tubs, or a finished basement.
- Evidence of overheating, corrosion, or damage in the existing panel.
- Insurance or home sale requirements that call out outdated equipment.
- Lack of open breaker spaces for new circuits.
Local insight: In Burlington, Montpelier, and Winooski, we often see older panels that were fine before, but winter heating, space heaters, and snow‑melt or garage loads push them past comfort. A 200 amp upgrade brings capacity and modern protection into alignment.

What “200 Amp Service” Really Includes
Upgrading is more than swapping a box. A complete 200 amp service upgrade typically includes:
- Service equipment and meter base rated for 200 amps.
- New main panel rated for 200 amps, with adequate breaker spaces.
- Correct service entrance conductors and grounding/bonding upgrades.
- Replacement of aging breakers and addition of AFCI/GFCI protection where required.
- Surge protection to help shield sensitive electronics.
- Labeling, torqueing, and documentation for inspection.
Lloyd offers turnkey solutions that bundle safety devices with panel work. Recent projects on our site show panel upgrades paired with surge protection, arc‑fault breakers, GFCI protection, and smoke detector installation for a comprehensive safety package.

Safety First: Code Compliance, Protection, and Peace of Mind
Electrical panels age. Breaker malfunctions can lead to shocks or fires if left unaddressed. A proper 200 amp upgrade aims at two outcomes: added capacity and a safer, code‑compliant installation.
Key protections we often include during panel and service upgrades:
- AFCI breakers reduce arc‑fault fire risks in many living areas.
- GFCI breakers or outlets protect kitchens, baths, garages, and outdoor circuits.
- Whole‑home surge protection helps guard electronics from utility or storm events.
- New smoke detectors placed according to current safety guidance.
From our site: “With an electrical panel upgrade, you’ll be able to enjoy a safer home that complies with electrical code standards.”
"Alec and Jason did a very thorough review for us."
Signs Your 100 Amp Panel Is Limiting You
If you experience one or more of these, an upgrade may be the right move:
- Two appliances cannot run without tripping a breaker.
- You have tandem breakers shoved into limited spaces to make room.
- Scorch marks, rust, buzzing, or a warm panel cover.
- Plans for an EV charger or hot tub but no remaining capacity.
- Aluminum branch circuits or recalled breakers that warrant attention.
Real‑world example from our project notes: “A panel swap was necessary… we also replaced a couple of outlets and installed two GFCI breakers.”
"Eric and his partner were attentive and flexible in determining the selected options."
Common Add‑Ons With a 200 Amp Upgrade
When you increase service capacity, it is the perfect time to add circuits and safety features:
- EV charger circuits: many Level 2 chargers use a 50A, 240V receptacle or hardwired 240V circuit. We routinely install 50A receptacles and dedicated circuits for chargers.
- Heat pump or electric range circuits: right‑sized breakers and wire for efficient operation.
- Garage or workshop power: additional 120V GFCI outlets or a small sub‑panel.
- Surge protection and smoke/CO detectors: bundled for whole‑home safety.
From our site’s job logs: “We installed two new outlets: a 50A receptacle for the EV Charger and a standard 120V GFCI outlet. Additionally, we implemented surge protection and installed a smoke detector.”
"Lloyd home service installed a new sub panel and dryer circuit for us. Joey was knowledgeable, professional, communicative, and very prompt. Pricing was fair and transparent. Would highly recommend Lloyd for electrical work!"
What It Costs in Central Vermont and Why
Every home is unique, but here are the main cost factors:
- Service location and utility coordination: meter/mast upgrades, overhead vs. underground.
- Panel brand and size: standard 40‑space vs. larger capacity for future expansion.
- Grounding upgrades: ground rods, bonding to water service, and service entrance conductors.
- Add‑ons: EV circuits, surge protection, AFCI/GFCI breakers, smoke detectors, sub‑panels.
- Permit and inspection fees required by your municipality.
Financing is available on our site for larger projects. Our No Surprise Upfront Pricing means you will see the full scope and investment before work begins.
Hard facts that help our clients budget smarter:
- Our Home Protection Club lists a reduced regular electrical dispatch fee of $69 and a reduced emergency electrical dispatch fee of $150 for members. Members also receive a 15% discount on qualifying electrical repairs. These benefits can offset maintenance costs after your upgrade.
- The membership is a one‑year minimum contract and auto renewing, which keeps routine electrical safety checks on schedule.
Permits, Inspection, and Utility Coordination
A 200 amp upgrade involves permits and inspections. We handle the paperwork, schedule the inspection, and coordinate necessary steps with your power provider. In Burlington, Essex Junction, Williston, and Montpelier, timelines can vary by inspector and utility workload, especially during peak construction months.
What we do for you:
- Evaluate existing service drop, meter base, grounding, and panel condition.
- Prepare a scope of work that meets current code and local requirements.
- Pull permits and schedule your inspection.
- Coordinate any utility shut‑offs or meter work.
- Complete installation and walk you through labeling and operation.

How To Prepare Your Home in Burlington, Colchester, and Nearby
Make installation smoother with a little prep:
- Clear a 3‑ to 4‑foot space in front of the panel and meter area.
- Unplug sensitive electronics. Whole‑home surge helps, but it is smart to unplug.
- Plan for a partial day without power. We protect refrigerated items and restore power as soon as it is safe to do so.
- Keep pets and kids away from the work zone. We maintain a clean, safe workspace.

Choosing the Right Electrician for a 200 Amp Upgrade
A service upgrade is not a handyman job. Look for:
- Proven local installations with permit and inspection experience.
- Clear, written proposals with parts, labor, and protections detailed.
- Ability to bundle safety devices like AFCI/GFCI and surge protection.
- Membership or maintenance options that keep your system safe long term.
Lloyd’s recent project notes highlight turnkey solutions and local experience across Central Vermont. Examples include: “For this customer we installed a new electrical panel in the garage,” and upgrades where we “provided estimates for a panel upgrade, new smoke detectors, surge protection and arc fault breakers to improve the home’s overall electrical system.”
Timeline: How Long Does It Take?
Most 200 amp upgrades are completed in one working day once permits and utility coordination are set. Add‑ons such as EV circuits or sub‑panels can extend work into a second day. Weather can influence exterior meter or mast work, especially in winter. We will give you a clear schedule before we begin and keep you updated throughout.

After the Upgrade: Maintenance and Peace of Mind
A new panel still benefits from periodic checks. Our Home Protection Club includes an annual electrical inspection, priority service for emergencies, and a 15% discount on qualifying electrical repairs. Members also receive reduced dispatch fees for electrical service. This keeps your upgraded system safe and tuned for years.
Practical tips:
- Keep the panel front clear and the directory labels up to date.
- Call if you notice repeated tripping on any new circuit.
- Consider adding surge protection for cable and data lines if sensitive gear is present.

Frequently Asked Questions
Do I really need 200 amps, or can I add a sub‑panel instead?
A sub‑panel adds breaker spaces, not total capacity. If your main is already near its limit or you plan for EV charging, heat pumps, or a hot tub, a 200 amp service is the safer long‑term solution.
How long will my power be off during the upgrade?
Most service upgrades take one working day once permits and utility scheduling are set. We plan shut‑down windows to minimize impact and restore power as soon as it is safe.
Will my utility need to be involved?
Yes. We coordinate any required meter work or shut‑offs with your utility. Timing can vary by workload and whether your service is overhead or underground.
What add‑ons should I consider during the upgrade?
Common adds include whole‑home surge protection, AFCI/GFCI breakers, EV charger circuits, smoke detectors, and dedicated circuits for heat pumps or workshop tools.
Can I finance a 200 amp service upgrade?
Yes. Lloyd lists financing options on our site to help spread the investment on larger projects. Ask for details with your proposal.
