Is your panel keeping up?

Wilmington's median home was built in 1978, and with 86% of homes owner-occupied, most residents have lived here for years and expect their homes to be safe, reliable, and ready for modern living. Here are the signs your electrical panel needs attention:

Adding an EV Charger or Generator

EV chargers and standby generators require dedicated circuits and significant amperage. Most Wilmington homes built before 1990 need a service upgrade before these can be safely installed.

Burning Smell or Warm Panel

Heat or a burning smell near your electrical panel is a serious fire hazard, especially in Wilmington's older split-levels and colonials where panels may not have been updated in decades. Call us immediately.

Federal Pacific or Zinsco Panel

These recalled panels are common in Wilmington homes built in the 1960s and 70s. They're known fire hazards that fail to trip during overloads & most insurance companies now require replacement.

Lights Dim When Appliances Run

If your lights flicker when the AC, dryer, or microwave runs, your electrical service is undersized. This is a very common issue in Wilmington's larger single-family homes with aging electrical panels.

Planning a Renovation or Addition

Wilmington homeowners regularly invest in kitchen upgrades, finished basements, and home additions. New living space means new circuits and most panels from the 1970s and 80s don't have the capacity to support them safely.

Breakers Keep Tripping

Frequent trips mean your panel can't handle your home's demand. In a Wilmington home built in the 1970s or 80s, that's a sign your electrical system hasn't kept pace with today's appliances and technology.

Panel or Service Upgrade FAQ's

Do I need a permit for a panel upgrade in Wilmington?

Yes, all panel upgrades in Wilmington, MA require a permit and an inspection. Sylvester Electric handles all permit filing and scheduling with the City of Wilmington's Inspectional Services Department as part of every job. You don't have to manage any paperwork.

How long does a panel upgrade take?

Most residential panel upgrades in Wilmington are completed in a single day. You'll be without power for a few hours while the old panel is removed and the new one is installed and tested. We coordinate with your utility company in advance so the process runs smoothly.

What size panel does my Wilmington home need?

Most Wilmington homes built before 1990 are running on 100-amp service — which can't safely support modern appliances, EV chargers, and heat pumps all running simultaneously. A 200-amp service upgrade is the most common solution for Wilmington's single-family homes. Larger homes or those adding significant electrical load may benefit from a 400-amp service. We'll assess your specific setup during your free in-home estimate.

Is a Federal Pacific or Zinsco Panel Dangerous?

Yes, Federal Pacific (FPE) and Zinsco panels are known fire hazards and are common in Wilmington homes built in the 1960s and 70s. These panels can fail to trip during overloads, creating a serious fire risk. Many insurance companies in Massachusetts now require replacement before they'll renew a policy. Sylvester Electric safely removes and replaces these panels throughout Wilmington.
