Answers to Common Questions
View All FAQsWhat Is Considered an Electrical Service Upgrade for Homeowners?
An electrical service upgrade is the replacement and right‑sizing of your home’s incoming electrical equipment so it can safely handle modern loads and meet current code. Most homeowners pursue this when adding high‑demand equipment (like EV chargers or heat pumps) or when an older panel shows limits such as frequent trips or flickering lights. An upgrade typically focuses on the main service equipment and grounding system, includes permit and inspection steps, and is designed for both today’s needs and your next planned appliance. We regularly complete these projects for homeowners in the Norfolk area.
Typical components included:
- New main electrical panel and main disconnect sized for current and future loads
- Upgraded meter socket, service mast or service entrance wiring, and grounding/bonding
- Added subpanels or dedicated circuits for EV chargers, heat pumps, or generators
- Whole-home surge protection with permit and inspection coordination
If you notice burning smells or hot breakers, turn off the affected circuit and contact a licensed electrician immediately. <br/> Updated: 2026-03-09 <br/> Need help in Norfolk, MA?

The cost to upgrade from 100 amp to 200 amp service varies by home and is confirmed after an on-site inspection. If a panel upgrade is needed, our page notes it typically adds $1,500 to $4,000 to the project. Total service upgrade costs depend on existing service layout and code-compliance work; our licensed, in-house electricians have resolved complex configurations, including unusual service setups. We serve Weston and surrounding Massachusetts cities.

Upgrading to 200-amp service can include both a new panel and utility-service work. On our projects, the panel upgrade portion adds $1,500–$4,000. Final pricing is confirmed after an on-site assessment. Costs vary with meter location, service entrance path, panel relocation needs, and utility/inspection coordination. We handle assessments and upgrades with our in-house, licensed electricians serving Newton, Weston, Worcester, and nearby towns.

Upgrading to a 200-amp electrical panel typically falls in the $1,500–$4,000 range. This reflects our documented panel-upgrade adders on electrification projects. Exact pricing depends on an on-site assessment, especially if you need a full service upgrade, panel relocation, or added AFCI/GFCI breakers. We handle complex existing-service configurations and can tie panel work into EV charger or heat pump installs.
Quick prep:
- Share photos of your current panel and main breaker rating.
- Note EV/heat pump plans and available breaker spaces.
- Tell us if the panel location must move.

Upgrading a fuse box to a modern breaker panel typically adds $1,500 to $4,000 to the project cost. In Weston and Newton homes, the final price depends on site conditions and code updates. We assess capacity, replace or relocate the panel as needed, and coordinate inspection for compliance.
Variables that change price:
- Amperage (e.g., 100A to 200A service)

Most home electrical panel replacements cost $1,500 to $4,000. This range comes from our project pricing where panel upgrades add $1,500–$4,000 to electrification work. Final cost depends on amperage (e.g., 100A to 200A), panel condition or relocation, and added loads like EV chargers or heat pumps. We handle complex service configurations and ensure code compliance with inspection as part of our process. Service available across Greater Boston, including Newton and Cambridge.
- Factors: amperage size, relocation, added loads, site complexity.

Professional fuse box replacement typically costs $2,500–$7,000 when upgrading to a modern breaker panel. Most of the price comes from the service-upgrade scope, with our electricians handling permits and inspections as part of the project. If your home still uses fuses, replacement is commonly chosen to improve safety, capacity, and code compliance. In older homes, stepping up to 200-amp service is often the biggest cost driver, not the panel hardware itself. We regularly complete these upgrades across the Northborough area and coordinate local inspections to keep the process smooth.
Cost can vary based on:
- Service size (e.g., 100A to 200A) and any meter/main service work
- Panel relocation or bringing grounding and bonding up to code
- Added circuits for EV chargers, heat pumps, or generators
- Existing wiring condition plus permit and inspection fees
If you smell burning or feel heat at the panel, treat it as an emergency and shut power off if safe. <br/> Updated: 2026-03-30 <br/> Need help in Northborough, MA? Call (508) 501-9990 or book online. “They installed a new electrical box and left the place looking great.” — Leah M.
