Straight answer
Yes. We do electrical work across Medford, and fuse box replacement is one of the most common requests, often after an insurer or a home inspector flags the panel. We swap the fuses for a breaker panel sized to the house, correct any overfused circuits we find, and tell you plainly whether the wiring behind the panel needs work too. Phones are answered 24/7.
The real hazard in a fuse panel
Fuses themselves protect wire well. The trouble is what people do to them. When a 15 amp fuse keeps blowing, someone screws in a 20 or a 30, and now the wire can overheat long before the fuse gives up. We find this in older houses all the time, especially on kitchen and basement circuits. A penny behind a fuse or a bypassed cartridge is rarer, and much worse.
The other limit is capacity. Many fuse panels are fed by a 60 amp service with a small number of circuits. Add a window air conditioner, a microwave and a space heater on a cold night and the fuses let you know. Replacing the panel and the service at the same time usually makes more sense than replacing the panel alone, and we explain why for your particular house.
Older Massachusetts housing and what sits behind the panel
Compared with most states, Massachusetts is heavy on houses built before 1940, and a Medford house of that age usually began on fuses with a handful of lighting circuits. Outlets came later, wherever someone found an easy path through the walls. That is why a fuse box swap here is never just a box swap. Before we price it, we check the grounding, look at what kinds of cable feed the panel, and test whether any knob and tube is still live somewhere in the house.
What happens on replacement day
A fuse box replacement is usually a one day job with the power off for most of it. We coordinate the disconnect with Eversource when the service is changing, set the new meter socket and panel, and land each existing circuit on a correctly sized breaker. Every circuit gets tested and labeled. AFCI and GFCI protection go in where current code requires them for the work being done.
Old cloth-covered cable sometimes crumbles when we move it into the new panel. When that happens, we tell you before going further and replace the damaged section back to sound insulation. If a large part of the house still runs on early wiring, we write up a rewiring plan as a separate step, so the panel job does not grow without your say. The city wiring inspector signs off before we close up.
Sizing the new panel for electric heat and cooking
Many Medford owners replacing a fuse panel are also thinking about heat pumps, an induction range or an EV. Those loads change the size of service you want. A 100 amp panel may cover a modest house today and run short the day a heat pump goes in. Sizing for what you expect to add costs less than upgrading twice.
We run a load calculation with the equipment you are considering, even if it is a year or two away, and show you what each choice leaves for headroom. Sometimes a 150 or 200 amp service is the right call. Sometimes a smart panel or a load management device lets a smaller service carry the new loads without a bigger utility upgrade.

Some insurers ask about fuse panels at renewal or at purchase, and their requirements vary. We can replace the panel and give you the paperwork showing the new equipment and the permit.
No. The fuse size is matched to the wire. A bigger fuse lets the wire overheat inside the wall before anything trips. A fuse that keeps blowing means the circuit is overloaded or has a fault.
Usually most of one working day. If the service and meter change too, timing also depends on the Eversource disconnect and reconnect, which we schedule in advance.
Not necessarily. Many houses have wiring in decent shape behind the old panel. We test the circuits as we move them and tell you if any sections need replacing.
Yes. Phones are answered 24/7, and urgent problems like a burning smell or dead circuits get an electrician sent out.
