Electrical Panel Upgrades

When Your Panel Needs an Upgrade

Not every panel issue means a full replacement. But certain signs indicate your panel has reached its limits:

• Panel is 25+ years old — breakers degrade, bus bars corrode, and capacity rarely meets modern demand
• Breakers trip frequently — especially if resetting them only works temporarily
• You're adding load — EV chargers, new HVAC, server rooms, or production equipment often exceed existing panel capacity
• Federal Pacific or Zinsco panels — these brands have documented failure rates and most insurers flag them
• Fuse panels — fuses don't provide the same protection as modern breakers and limit your options for adding circuits
• Visible damage — rust, burn marks, melted plastic, or a warm-to-the-touch panel cover
• Insurance requires it — some carriers require panel upgrades before issuing or renewing commercial policies

Commercial Panel Upgrades

Commercial electrical panels handle heavier loads, serve more circuits, and need to meet stricter code requirements than residential panels. Our commercial panel upgrade services include:

• Main distribution panel replacements — 200A through 4000A
• Sub-panel additions — for tenant buildouts, office expansions, and equipment additions
• 3-phase panel installations — for industrial equipment, motors, and heavy machinery
• Meter and service upgrades — coordinated with Eversource for seamless utility transitions
• Code compliance upgrades — bringing panels up to current NEC (NFPA 70) standards
• Arc fault and ground fault protection — AFCI/GFCI breaker installations where required by code

We handle the full process — load calculation, permit filing, utility coordination, installation, and final inspection. Most commercial panel upgrades are completed in one to two days with minimal disruption to your operations.

Residential Panel Upgrades

For homeowners, a panel upgrade is often the single most impactful electrical improvement you can make. It increases your home's capacity, improves safety, and can resolve issues that have been causing problems for years.

Common residential upgrades include 100A to 200A service upgrades, fuse box to breaker panel conversions, Federal Pacific and Zinsco panel replacements, and adding sub-panels for home additions, workshops, or EV charger installations.
