Electrical Service Upgrades in Hamilton, MA
A lot of Hamilton homes sit on lots big enough that the driveway alone is a quarter mile, and the electrical service was sized decades ago for a house half its current draw. Add a well pump, a barn, a heated garage, and a generator transfer switch, and a 100 amp service that was fine in 1975 is now the reason your lights dim when the well kicks on.
Why Hamilton Homes Need This
Hamilton is low-density and rural in character. That means longer utility lines from the substation, and it means when a storm takes a tree into the wires, homes here are often last back on. That single fact drives more service upgrade calls in this town than anything else: a generator big enough to run a well pump, a septic pump, and heat needs a service and panel that can actually support it, not just a 30-amp inlet bolted onto an old 60 amp panel.
The housing stock adds to it. Hamilton has a real share of older farmhouses and estate-style properties, some dating well before the 1960s. On these, we still find cloth-insulated wiring, knob and tube in parts of the attic or basement that were never touched during a remodel, and original 60 amp fused services. Some homes went through a mid-century upgrade and landed on a Federal Pacific Stab-Lok or Zinsco panel, both of which have documented breaker failure issues and get flagged by inspectors and insurers alike. None of that is unusual for this area. It is just the reality of a town where houses last a long time and the electrical system doesn’t always get touched when everything else does.
What the Work Involves
A service upgrade from 100 to 200 amps touches three things: the utility’s overhead or underground drop, the meter socket, and the electrical panel itself. Brandon handles the meter socket, the mast (the pipe carrying the service wires up the side of the house), the grounding system, and the panel and breakers. The utility owns the transformer and the wire coming to your house, and they have to schedule the disconnect and reconnect on their end.
On the day of the work, power is off for most of the day, sometimes into the next if the utility’s crew is backed up. Brandon pulls the old meter, replaces the mast and weatherhead if they’re undersized or corroded, installs a new 200 amp panel with breaker spaces for everything you actually run, and re-grounds the system to current code using ground rods and bonding that a lot of 1960s and 70s installations never had. If knob and tube or cloth wiring is still live anywhere in the house, that’s a separate conversation, but it often gets identified during this job because the old panel gets opened up.
What It Costs
A straightforward 100 to 200 amp upgrade in Hamilton typically runs {PRICE_LOW} to {PRICE_HIGH}. What moves the number: whether the service is overhead or underground (underground trenching costs more), how far the mast has to run, whether the meter socket location has to move, and whether the utility requires a new transformer tap because of the added load. Generator-ready setups with a transfer switch add to the job but are common enough here that we quote them together more often than not. There’s no flat number that’s honest for every property, especially on lots with long runs from the road.
How Long It Takes
The physical work at the house is usually a single day, sometimes two if the mast, weatherhead, and grounding all need replacing along with the panel. The bigger variable is the utility. National Grid has to schedule the disconnect before Brandon can work and the reconnect after inspection, and that scheduling window is out of our hands. In Hamilton, where crews are covering a wide, low-density area, that can add a few days to the calendar even though the labor itself doesn’t take long.
Permits and Inspection
This work is permitted through the Hamilton building department and inspected under the Massachusetts Electrical Code, which follows the National Electrical Code with state amendments. [EXTERNAL LINK: Massachusetts Board of State Examiners of Electricians – state electrical code and licensing information] A permit gets pulled before the work starts, an inspector signs off on the grounding, panel, and mast before the utility will reconnect permanently, and the paperwork stays on file with the town. That inspection step is the difference between a licensed job and the kind of work that shows up as a red flag when you go to sell the house or file an insurance claim. Brandon pulls the permit and schedules the inspection as part of the job, not as an extra.
Common Questions
How do I know if my house needs a service upgrade versus just a new panel?
If your panel is failing, obsolete, or recalled, that's a panel replacement. If your panel and wiring are fine but you don't have enough amperage for what you want to add, that's a service upgrade, since it involves the utility's meter and drop, not just the box on the wall. Brandon can tell you which situation you're in by looking at the panel and doing a load calculation.
Will I lose power during the upgrade?
Yes. Power is off for most or all of the work day while the meter, mast, and panel are disconnected and replaced. We coordinate the timing with the utility so the outage is as short as it can be, but there's no way to do this work live.
Do I need a permit for this in Hamilton?
Yes. A service upgrade always requires a permit from the local building department and a follow-up inspection under Massachusetts electrical code before the utility will restore permanent power. This isn't optional and it isn't something a licensed electrician skips.
Is a 200 amp service enough for a generator and an EV charger?
In most Hamilton homes, yes, especially with a load calculation done properly and breakers sized to match actual usage rather than guesswork. Some larger properties with well pumps, heat pumps, and multiple outbuildings may need more planning, which is exactly why the load calculation happens before, not after, the panel goes in.
What's the difference between what the utility does and what Belfiore does?
The utility owns the transformer and the wire running to your property, and only they can disconnect and reconnect service. Brandon handles everything from the meter socket inward: the mast, the meter base, the grounding, and the panel itself. Coordinating both sides so the timeline makes sense is part of the job.

Talk to Brandon
Brandon left union electrical work to run the electrical side of this family business, and service upgrades are some of the most technical work he does: reading a load calculation correctly, sizing wire and breakers to match, and coordinating with the utility so the house isn’t without power longer than it has to be. If you’re not sure whether your panel is a Federal Pacific or Zinsco, or whether your 100 amp service can even handle a generator and an EV charger down the road, he can look at the panel and give you a straight answer.
