Safety & warning signs
I smell something burning near an outlet or the panel. What should I do?
Turn off the breaker for that circuit, or the main breaker, if you can reach it safely, then call an electrician. If you see smoke or flames, get everyone out and call 911.
Do not keep using the outlet or reset the breaker to see if it happens again. A burning smell usually means a connection is overheating, and it can get worse quickly.
Is a warm outlet or switch plate dangerous?
A dimmer can feel slightly warm in normal use, but an outlet or switch that is hot, discolored or buzzing is a warning sign. Turn that circuit off at the panel and have it checked.
The usual causes are a loose connection, a worn device or a circuit carrying more than it should. All of them are fixable, and all of them are worth fixing before they cause a fire.
Half the house lost power but the rest is on. What does that mean?
It often points to a problem with the service, such as a failed connection on one leg or a loose neutral, rather than a single tripped breaker. Turn off the main if it is safe, call the utility to check their side, and call an electrician.
If lights are getting unusually bright or appliances are acting strangely, unplug sensitive electronics. A lost neutral can push the wrong voltage through the house.
What should I do about a downed power line?
Stay far away from it, keep others away, and call your utility (Green Mountain Power for most of Bennington County) or 911. Treat every downed line as live, even if it isn’t sparking.
Never try to move a line, and don’t drive over it. If a line is on your car, stay inside unless the car is on fire.
My breaker keeps tripping. Can I just replace it with a bigger one?
No. The breaker is sized to protect the wire in the wall. A bigger breaker lets that wire overheat before anything trips, which is how electrical fires start.
A breaker that trips repeatedly is telling you something: an overloaded circuit, a short, a ground fault or a failing appliance. Have the cause found.
When should I worry about flickering lights?
A brief dim when a big motor starts, like a well pump or furnace blower, is common. Flickering that is getting worse, lights that brighten, or flicker across the whole house should be checked soon.
Those symptoms can point to a loose connection in the panel or at the service. Loose connections heat up over time, so it is not something to live with.
Old houses & old wiring
Is knob-and-tube wiring dangerous?
It isn’t automatically dangerous, but at its age it is a risk. Knob-and-tube has no ground, its insulation gets brittle, and it was designed to shed heat into open air, not to be buried in modern insulation.
Many insurers ask about it. We recommend testing what is still in service and replacing it in stages, starting with the circuits that carry the most load.
We still have a fuse box. Does it need to go?
Not always, but most fuse boxes were sized for a fraction of what a modern house uses, and the common workarounds (oversized fuses, pennies behind fuses) are dangerous.
If fuses blow often, or you are adding a heat pump, an EV charger or a kitchen, replacing the fuse box with a modern panel is usually the right step.
Are Federal Pacific or Zinsco panels a problem?
Federal Pacific Stab-Lok and Zinsco panels have long-documented reputations for breakers that may not trip when they should. Many electricians, inspectors and insurers recommend replacing them.
If you have one, have it looked at. A panel replacement is a straightforward job that removes a known risk.
What about aluminum wiring?
Aluminum branch-circuit wiring, used in some homes in the 1960s and 1970s, can loosen and overheat at connections. It is not something to ignore, and it is not a do-it-yourself fix.
The accepted repairs are approved connectors at each connection point or replacing the circuits. An electrician should do the work.
My house has two-prong outlets. Can I just swap in three-prong ones?
Not without a ground. A three-prong outlet on an ungrounded circuit looks safe but isn’t. The code allows a GFCI outlet as a replacement on ungrounded circuits, labeled ‘No Equipment Ground’, or the circuit can be rewired with a ground.
Which option is right depends on what you plug in. Computers and surge protectors need a real ground to work as intended.
How do you rewire an old house without tearing out the plaster?
By planning routes through attics, basements, closets and baseboards, and fishing cable through the walls with small, patchable openings.
Some walls still need a cut or two. We plan the route with you before we start so you know where they will be.
Storms, outages & generators
Can I plug my portable generator into a dryer outlet to power the house?
No. That is called backfeeding, and it can send power back into the utility line, where it can kill a lineworker or a neighbor. It can also start a fire in your house.
The safe way is a generator inlet with an interlock kit or a transfer switch, installed by an electrician, so the house is disconnected from the grid before the generator feeds it.
What is a generator interlock, and is it enough?
An interlock is a mechanical plate on your panel that makes it impossible to turn on the generator breaker while the main breaker is on. Paired with a proper inlet, it is a safe and affordable way to run chosen circuits from a portable generator.
A transfer switch does the same job with a separate panel of selected circuits. Both work; the choice depends on your panel and how you want to use the generator.
What size generator do I need to run my well pump and furnace?
It depends on the equipment. Well pumps have a high starting load, so a generator that runs them comfortably is often larger than people expect. We check the nameplates and help you pick a size.
A typical essentials list in the hill towns is the well pump, the boiler or furnace, the refrigerator, a few lights and a phone charger.
Where should a portable generator sit when it’s running?
Outdoors, well away from doors, windows and vents, never in a garage, basement or porch, even with the door open. Generator exhaust contains carbon monoxide, which kills quickly and has no smell.
Have working carbon monoxide alarms on every level of the house, especially if you use a generator or burn fuel for heat.
Do I need whole-home surge protection in Vermont?
It’s a good idea. Lightning, utility switching and power returning after an outage can all send surges through the house, and furnaces, boilers, heat pumps and appliances now have circuit boards that surges can damage.
A surge protector installed at the panel protects every circuit. Plug-in strips are still useful for electronics as a second layer.
Our basement flooded. Is it safe to turn the power back on?
Not until wet electrical equipment has been inspected. If the panel was under water, leave the main off and call the utility and an electrician. Never stand in water to work a breaker.
Submerged breakers, outlets, panels and many appliances should be replaced rather than dried and reused. Water leaves corrosion and contamination behind.
Panels, heat pumps & EV chargers
How do I know if I need a service upgrade?
Common signs are a full panel with no room for new breakers, frequent trips, a 60- or 100-amp service, or plans to add a heat pump, an EV charger, an electric range or a hot tub.
A load calculation answers the question properly. It adds up what you have and what you plan to add and compares it with what the service can carry.
Can my panel handle a heat pump?
Many can, but a heat pump needs its own 240-volt circuit and adds real load, especially if it is the main heat. We check the panel’s capacity and space before you commit to equipment.
If the panel is full or the service is small, an upgrade or a load-management device may come first.
What does a Level 2 EV charger need?
A dedicated 240-volt circuit sized for the charger, usually 40 to 60 amps, and a panel with the capacity for it. Hardwired chargers and plug-in chargers on a 240-volt outlet both work if installed correctly.
Green Mountain Power has offered EV charger incentives and programs; check their current offers before you buy.
What’s a subpanel, and when do I need one?
A subpanel is a smaller panel fed from your main panel. It makes sense for a garage, workshop, addition or finished basement, where it is easier to run one feeder than many separate circuits.
It doesn’t add capacity to your service. If the main service is already near its limit, that has to be dealt with first.
Why does my power company have to be involved in a service upgrade?
Because the service connects to their equipment. Your electrician coordinates with the utility to disconnect and reconnect the service, and in many cases to set a new meter.
In Bennington County that is usually Green Mountain Power. We handle the coordination for you.
Everyday fixes & projects
Why do my bathroom and kitchen outlets have test and reset buttons?
Those are GFCI outlets. They cut power in a fraction of a second if current leaks to ground, such as through water or a person, and they are required near sinks, in bathrooms, garages, basements and outdoors.
Press test once a month; the outlet should click off. If it won’t reset or trips constantly, have it checked.
My bathroom gets steamy and the fan barely works. What can be done?
Usually the fan is undersized, worn out, or vented into the attic instead of outside. A properly sized fan vented out of the house clears moisture before it turns into mold and peeling paint.
Bath exhaust fans are one of the jobs we do regularly.
Can a ceiling fan go where my light fixture is now?
Often, yes, but the box has to be rated to support a fan. A standard light box isn’t built for the weight and vibration. We swap in a fan-rated box or brace and wire the fan and light to the switches you want.
Is heat tape on my pipes or roof an electrical concern?
It can be. Heat cable should plug into a GFCI-protected outlet, be the right type for the job, and be installed according to its instructions. Old, damaged or overlapped heat tape is a known fire risk.
If you rely on heat cable every winter, have a dedicated, protected outlet installed where you need it.
Do you install central vacuum systems?
Yes. Central vacuum systems appear on our listings, and we install and repair their power unit circuits and wiring. Tell us what system you have or are planning.
How many smoke and CO alarms should a Vermont home have?
Smoke alarms belong inside every bedroom, outside each sleeping area and on every level, and carbon monoxide alarms outside sleeping areas and on every level with fuel-burning equipment. Vermont also has specific alarm requirements when a single-family home is sold.
Interconnected, hardwired alarms with battery backup are the gold standard: when one sounds, they all do.
Permits, licensing & hiring
Who licenses electricians in Vermont?
The Vermont Division of Fire Safety, part of the Department of Public Safety, licenses electricians through its Electrical Licensing program. Licenses include master and journeyman levels.
You can check a license on the Division of Fire Safety’s online license lookup.
How do I check that an electrician is licensed?
Ask for the electrician’s Vermont license number and look it up with the Division of Fire Safety. A master electrician’s license starts with EM and a journeyman’s with EJ.
Also ask whether they carry liability insurance and whether the job needs a permit. A good electrician answers all three without hesitating.
Does electrical work in Vermont need a permit and inspection?
It depends on the building and the work. Commercial buildings and rental housing are public buildings under Vermont’s fire safety rules, and electrical work in them is permitted and inspected by the Division of Fire Safety. Rules for owner-occupied single-family homes are different.
A licensed electrician will know what applies to your job and file what is required.
What electrical code does Vermont follow?
Vermont adopts the National Electrical Code (NEC) through its electrical safety rules, with state amendments. The edition in force changes as the state updates its rules.
That matters for things like GFCI and AFCI protection, which newer editions expand.
Can I do my own electrical work?
Changing a light bulb or plugging in a lamp, of course. But panel work, service work, feeders and new circuits are jobs for a licensed electrician. Mistakes there cause fires and shocks, and they can affect your insurance and a future sale.
If you’re not sure whether a job is safe to try, it isn’t. Call and ask.
What should a good estimate include?
The scope of work in plain words, the price, what is and isn’t included, whether a permit is needed, and roughly when the work can be done.
Our estimates are free, and you get the price before any work starts.
