100A to 200A service upgrades, Federal Pacific/Zinsco hazard replacement, and circuit additions across Salem, Beverly, Peabody, Danvers, Marblehead & all of Essex County. Mass Save rebates up to $2,500. Free estimates.
Zolotas Electric handles electrical panel upgrades across every town in Essex County. Whether your Salem colonial needs a Federal Pacific replacement or your Peabody home needs capacity for a heat pump, Greg assesses each property individually and provides a clear, itemized scope.
Your electrical panel is the backbone of your home's wiring system. When it's undersized, outdated, or hazardous, everything downstream suffers — from flickering lights to inability to add modern appliances. Here's what drives most Essex County homeowners to call Zolotas Electric:
Federal Pacific (FPE) and Zinsco breaker panels were installed in millions of homes built between 1950 and 1990. They have a documented design defect: the breakers frequently fail to trip under overload conditions, allowing dangerous heat buildup in the panel. Federal Pacific panels were banned in new construction after 2011; Zinsco panels are no longer manufactured for the same reason. If your home has either panel, replacement isn't optional — it's a fire safety issue. Insurance companies often refuse to cover homes with these panels, and many home buyers walk away from a purchase if the panel isn't replaced before closing.
A 100-amp panel built in the 1960s wasn't designed for modern loads. Today's homes run ductless heat pumps, Level 2 EV chargers, induction ranges, central AC, multiple refrigerators, home offices, and smart home systems simultaneously. A 100-amp panel with electric heat, a dryer, and a stove is already near capacity — adding a heat pump or EV charger pushes it over the edge. Upgrading to 200-amp service gives you headroom to run everything without tripping breakers.
Mortgage lenders, home inspectors, and insurance companies increasingly require panel upgrades before closing. A 100-amp service or a known hazard panel (FPE/Zinsco) can kill a deal or require expensive remediation during the closing process. Upgrading proactively — before you sell — puts you in a stronger negotiating position and can actually increase your home's value.
Every heat pump installation and Level 2 EV charger installation in Massachusetts requires a panel capacity check. If your home has 100-amp service, you almost certainly need an upgrade before either can be installed. Doing the panel work first prevents delays with your HVAC or EV installer and may qualify you for a Mass Save rebate of up to $2,500.
Full service replacement for homes with 100-amp service that need more capacity. Includes permit, utility coordination, panel, and inspection.
Complete hazard panel removal and replacement. Modern Square D, Eaton, or Siemens panel with code-compliant wiring. Insurance-compliant.
Replacing outdated fuse boxes with modern breaker panels for improved safety and capacity. Common in pre-1965 Essex County homes.
Adding new circuits to an existing panel — for home offices, garage workshops, EV chargers, or heat pump installations.
Every home is different, but these three upgrade scenarios cover most of what Zolotas Electric sees in Essex County. If your situation doesn't match one of these, call anyway — Greg will assess your specific home.

A standard 100A to 200A panel upgrade in Essex County typically costs between $1,800 and $4,500 depending on scope. Basic 200A service replacement runs $1,800–$2,800. Replacing a Federal Pacific or Zinsco hazard panel runs $2,500–$4,000. Sub-panel additions run $800–$1,500. Permit fees and utility coordination add $300–$600 on top. Mass Save may rebate up to $2,500 of the total cost when combined with a heat pump or EV project. Zolotas Electric provides itemized, free estimates — no surprises.
Three main reasons: (1) Safety — Federal Pacific and Zinsco panels have known design defects where breakers fail to trip under overload, creating a fire hazard. These panels are banned in new installations but still common in older Essex County homes. (2) Capacity — Modern homes run heat pumps, EV chargers, induction ranges, central AC, and multiple electronics simultaneously. A 100-amp panel built for a 1960s home can't keep up. (3) Home sale and insurance — Many buyers and insurers require panel upgrades before closing.
Mass Save covers electrical panel upgrades done as part of comprehensive electrification — heat pump installation, EV charger installation, or whole-home electrical improvements. The maximum rebate for panel upgrade electrical work is $2,500. The electrical work must be completed by a licensed MA electrician to qualify. Zolotas Electric has completed dozens of Mass Save electrical projects in Essex County and knows the application requirements.
A panel upgrade takes one full day for the physical installation — panel swap, wiring, circuit labeling. Utility coordination adds 1–4 weeks depending on the utility's schedule. Permit and inspection typically happen within 1–2 weeks of the work. Total timeline from first call to final inspection: 2–5 weeks. Zolotas Electric handles all permit applications and coordinates with the utility on your behalf.
Federal Pacific (FPE) and Zinsco panels — common in homes built 1950–1990 — have documented design flaws. Their breakers frequently fail to trip under overload conditions, allowing dangerous heat buildup. Federal Pacific panels have been banned since 2011; Zinsco is no longer manufactured. Modern panels use UL-listed circuit breakers (Square D, Eaton, Siemens) that trip reliably under overload. If your home has a FPE or Zinsco panel, replacement is strongly recommended. Insurance companies often won't cover homes with these panels, and many buyers walk away.
In most cases — yes. A ductless heat pump outdoor unit draws 20–40 amps at 240V; a whole-home heat pump can draw 40–60 amps. A Level 2 EV charger draws 40–50 amps. If your home has 100-amp service and already runs an electric stove, dryer, or water heater, adding a heat pump or EV charger will push the panel over capacity. Upgrading to 200A is typically required. Mass Save may rebate up to $2,500 of panel upgrade costs when done as part of a heat pump project. Zolotas Electric does a full load calculation during every free estimate.
Warning signs: (1) Frequent tripped breakers — your panel trips when you run the microwave and toaster simultaneously. (2) Flickering lights when high-draw appliances turn on. (3) 100-amp service — if your home was built before 1990 and hasn't been updated, you likely have 100-amp or smaller service. (4) Federal Pacific or Zinsco panel — known fire hazards, replacement strongly recommended regardless of capacity. (5) Planning major electrification — adding heat pump, EV charger, induction stove, or hot tub requires a capacity check. Call (978) 535-6260 for a free assessment.
