Federal Pacific panel replacement in Boston

Dorchester triple-deckers and Newton colonials still hide Stab-Lok and Zinsco load centers. Inside the city the electrical permit is Inspectional Services. Homeowners cannot pull that permit. The meter is usually Eversource.

Boston’s older triple-deckers and colonials went up when Federal Pacific and Zinsco were ordinary hardware. Dorchester, Jamaica Plain, Southie, and the streets toward Newton and Quincy are the usual addresses. Castle’s Newton FPE page is written for houses built in that window. Castro’s Woburn page names both brands as the ones inspectors and insurers flag. The insurance letter is usually written somewhere else. The work is governed by Inspectional Services inside the city and, on most Boston bills, by Eversource.

Those two systems do not match. ISD issues the electrical permit. Eversource will not reconnect until the wiring inspector has called in the approval. A helper with a van is not the person who can print that permit or book the disconnect.

What Eversource actually wrote

Start with the Information and Requirements booklet for Eastern Massachusetts. Article 209 is the disconnect rule. When an overhead or underground service has to come down, you contact the New Customer Connect Tech Center. The company wants advance notice and a time both sides agree on. No service will be reconnected until Eversource receives approval from the authority having jurisdiction.

The Eastern Massachusetts underground-service page says the same thing in steps for a residential job under 400 amps. Get a work-request number. Do the work to Eversource standards. Get the municipal wiring inspection. Make sure the inspector has called the approval into Eversource. The published commitment is to energize within five business days of that call, or on a date you both agree, if rights, permits, and customer charges are finished.

That is not a homeowner meter-pull path.

Eversource does not publish a guaranteed power-off hour count. Castro describes about eight hours off on a 200-amp panel day. Sylvester describes a few hours off and one to two weeks of utility scheduling. Those are contractor field notes.

Confirm the logo on the bill. Most Boston addresses are Eversource. Some neighborhoods are National Grid. The ticket is not the same company.

Permits inside Boston and in the nearby cities

Inside the city, start at Inspectional Services. The electrical-permit page is blunt. If you are a homeowner, you must hire a licensed contractor to apply for the permit and complete the work. Homeowners cannot apply. The applicant has to be the contractor doing the work, and the name on the Massachusetts trade license has to match. The file needs a front-and-back copy of a valid license, current liability insurance, and a workers’-compensation affidavit.

Applications run through the ISD portal. After the work, the licensed contractor must be on site for the inspection. Call 617-635-5300 or schedule in the portal. Boston’s service-upgrade page repeats that only a contractor with a valid, non-expired Massachusetts trade license may apply for an Electrical Permit and perform work that installs or replaces electrical services or wiring.

Newton, Brookline, Cambridge, Somerville, Quincy, Woburn, and Stoneham each have their own wiring inspector. A quote that only says “we handle the permit” should name the city on the address.

Massachusetts license lookup is public. Ask for the Master Electrician number and check it on the Board of State Examiners of Electricians before you sign.

Price, without inventing one

Three contractor pages publish installed bands, and they do not match. Castle’s Newton replacement page prices a 100-amp upgrade at $1,500 to $3,000 and a 200-amp upgrade at $2,500 to $5,000, including materials, labor, and permitting. Castro’s Woburn FAQ prices a typical 100-amp to 200-amp upgrade at $2,500 to $4,500. Sylvester’s FPE/Zinsco page prices that brand swap at $2,500 to $4,500, an interior-only 200-amp swap at $2,195 to $3,495, and a full 100-amp to 200-amp service upgrade at $6,200 to $10,500. Those can all be true if they are describing different scopes. We will not average them.

Two shops advertise this work on their own sites and print a number. Castle’s Federal Pacific page names Stab-Lok panels and prints A16191. Castro’s Woburn page names Federal Pacific and Zinsco and prints 24276-A. Castle is based in Norwood and writes Newton as a primary market. Castro lists Stoneham and Greater Boston. They are listed for the panel letter, not as a North Shore directory.

Directory-only shops are omitted. A page that names these brands and does not print a Massachusetts license is a cost source, not a listing. Neither listed shop is affiliated with Panel Letter.

What to hand the carrier

The useful packet is the closed ISD or town electrical permit, the inspection approval Eversource needs before reconnect, an invoice with the Master Electrician number on it, and photos if the letter asks. If your electrician produces a load calculation or panel schedule, send that too. We did not find a carrier page that publishes a single statewide “sticker” form. Ask the agent what they will actually open.

Electricians who advertise this job

A shop is listed only if it advertises Federal Pacific, Zinsco, or insurance-driven panel replacement on its own site and prints a license number there. Trade-association locators already exist. We will not pad this list. Verify the license before you hire.

To get introduced, use the quote form on this page. We do not send you to the shop from here.

Request quotes from licensed electricians who do insurance-flagged panel replacement

We send this to Panel Letter and match it in Boston. No countdown clock, no “four quotes in 60 seconds,” nothing to Angi or Thumbtack.

Do you have an insurance letter about this panel?

Photo upload comes later. A picture of the closed door and the inside label is enough if someone asks.
