Electrician FAQs for Nassau County, NY
You usually call an electrician with one question in your head: is this safe, who handles it, and what happens next? This page answers the questions we hear most from Nassau County homeowners and business owners, in the order a job tends to unfold. Each answer starts with the short version, then adds the detail that matters on Long Island, such as town-by-town licensing, PSEG Long Island’s side of the meter, and the inspection that follows new wiring.
The short answers
- Licensing: Nassau County does not license electricians. Each city, town and village does, so the rules depend on the address of the job.
- Who owns what: PSEG Long Island owns the street lines, transformer, service drop and meter. You own the weatherhead, entrance cable, meter pan, panel and everything inside the house.
- New wiring: A new circuit, such as a 240-volt EV charger circuit, is permitted where your town requires it and inspected before you use it.
- Commercial power: A commercial service, or any service of 400 amps and up, needs a PSEG Long Island load letter.
- EV incentives: The federal home-charger tax credit ended for chargers placed in service after June 30, 2026. A PSEG Long Island rebate may still be available.
- Warning signs: A burning smell at the panel, sparking, or an outlet that is hot to the touch means stop using it and call an electrician. If you see smoke or flames, call 911 first.
Hiring an electrician in Nassau County
We cover all of Nassau County, from Long Beach and Freeport to Great Neck, Hicksville and Massapequa, and we also take jobs in western Suffolk, the five boroughs of New York City and Westchester. The process changes with the location, since Con Edison serves much of the city and Westchester and city jobs are filed with the Department of Buildings. We work from the rules for the address in front of us, not one template.
We start with a conversation about the problem, then look at the panel and the area involved. We give you a written scope, obtain the permit where your town requires one, and do the work. The inspection follows, and in Nassau that is usually done by a private agency the town has approved. You are not left to chase the paperwork afterward.
It depends on what the job involves, and any fixed number quoted before someone has seen the panel is a guess. The main factors are the scope of the work, how far the wiring has to travel, whether the panel or service has room, what finishes have to be opened and repaired, and the permit and inspection steps. A defined job, such as adding a circuit, is priced against a written scope. Troubleshooting is often priced by time, because the cause is unknown until it is found.
Not under their own authority, unless they also hold the electrical license for your town. A general contractor normally brings in a licensed electrician for the electrical portion. Unlicensed work can fail inspection, hold up a sale or complicate an insurance claim, which is why the license question matters even on small jobs.
Five questions cover most of it:
- Which license covers my town or village, and what is the number?
- Will you pull the permit and arrange the inspection?
- Can I have the scope of work in writing before you start?
- What happens if the inspector finds a problem?
- Who do I call if something trips again next week?
Vague answers are a signal. Specific ones, with town names and inspection steps in them, usually come from someone who works here every week.
Call when a breaker trips repeatedly, an outlet or switch is warm or discolored, you smell something burning, lights flicker or dim without a clear cause, part of the house has no power, or you are adding a major load such as an EV charger, hot tub or central air. Anything involving the panel or the service wires is not a wait-and-see job.
An electrician installs, repairs and tests the wiring and equipment that carry power through a building: panels, breakers, circuits, outlets, switches, lighting, service equipment and low-voltage systems. A good one also finds hidden faults, sizes circuits to the load, pulls permits and gets the work inspected. Most of the skill is diagnosis, knowing why something failed before replacing anything.
Ask for the license that covers your specific town or village, write down the number, and confirm it with that municipality’s building or licensing office. Nassau County Consumer Affairs takes complaints about electricians through its electrician complaint page, but it does not do the licensing. A reputable contractor hands over the details without hesitation.
An electrician licensed by the city, town or village where the property sits. The county does not issue an electrician license of its own. Hempstead, North Hempstead and Oyster Bay each run a separate licensing board, and many villages add a step of their own, such as a registration or a village permit form. Ask any contractor which license covers your address.
Home electrical problems
We install and replace recessed lighting, fixtures, dimmers, under-cabinet and outdoor lighting, and we add the circuits and switching that make them work. When a lighting job turns out to need new wiring, we say so before we start. The details are on our lighting installation page.
Get the report in front of an electrician before you negotiate. Findings such as double-tapped breakers, missing covers, ungrounded outlets or a panel from a problem brand vary from a few minutes of work to a serious repair. Our guide to electrical findings and the certificate of compliance explains how to sort them.
It depends on your municipality and on what you are changing. Some villages do not allow homeowners to do their own electrical work at all, and Freeport is one of them. Even where homeowner work is allowed, swapping receptacles in certain rooms, or adding and extending circuits, can trigger ground-fault or arc-fault protection under the current code. That is why a simple swap sometimes needs more than the part itself.
Only if testing says so. Age alone is not the test. We look at the wiring type, the condition of the insulation, how many circuits are overloaded, whether grounding is present and what the inspector or insurer has flagged. Some houses need a rewire, some need targeted replacement, and some are fine with a panel and a few circuits updated. See our wiring repair and rewiring page.
Not automatically, but it carries specific risks. Cloth-wrapped knob-and-tube insulation can become brittle and was never meant to be buried in modern insulation. Aluminum branch wiring from the 1960s and 70s can loosen at devices and overheat if it is not terminated with approved methods. What to do about each is in our guide to old house wiring in Nassau.
A brief dim when a large motor starts is normal. Lights that flicker constantly, or that dim along with other lights in the house, point to a loose connection or an overloaded circuit, sometimes at the service equipment itself. That deserves a look from an electrician, because a loose connection that arcs gets hotter over time.
Moisture is the most common reason, followed by a worn device, a ground fault in something plugged in, or a fault further down the same circuit that the GFCI is protecting. Replacing the outlet only helps when the outlet itself is the problem. The reasons, and how to tell them apart, are in why your GFCI keeps tripping.
Yes. A burning or fishy smell at the panel usually means a loose connection, an overheated breaker or insulation that has started to break down. Do not open the panel cover yourself, keep clear of it, and call an electrician right away. Our guide to a burning smell at the electrical panel covers what to do while you wait.
A breaker trips to stop heat, and the reason is usually an overloaded circuit, a short, a ground fault, or a tired breaker that no longer holds its rating. Resetting it again and again only tests the problem. If the same breaker trips more than once, unplug what is on it and have it tested. Our panel repair and upgrade page explains how we trace the cause.
Panels, service upgrades and PSEG Long Island
It follows a different path, because each village operates its own electric utility and PSEG Long Island is not involved. Freeport requires its own licensed master electrician to apply for the permit, and an inspector signs off before any wiring is closed up. Rockville Centre sets its own procedure, which we confirm with the village before giving you a price.
The 2023 code requires surge protection when a service or panel is replaced in a dwelling, so a new panel generally comes with it. Surge protection guards against spikes from the utility or a nearby strike, and it is especially useful for electronics and HVAC controls. We cover this in our panel repair and upgrade page.
Not by itself. The risks come from what has been done to it: oversized fuses, coins behind a fuse, too many added circuits, or no room left for new loads. A fuse box in good order can still be adequate. Many owners replace one because their insurer asks, the capacity is short, or they are adding something new.
Often, when service equipment is replaced. The 2023 National Electrical Code, adopted into New York’s 2025 Uniform Code, asks for an outdoor emergency disconnect so firefighters can cut power without entering the house. There is an exception when only the meter socket or the entrance cable is being replaced. See weatherhead and meter socket replacement.
For new or changed service equipment, yes. PSEG Long Island wants the inspection certificate before it reconnects. That is why the permit, the private inspection agency and the utility are all lined up before the work starts, not afterward. Our emergency electrician page explains how this changes after storm damage.
For new or changed service equipment, yes. PSEG Long Island wants the inspection certificate before it reconnects. That is why the permit, the private inspection agency and the utility are all lined up before the work starts, not afterward. Our emergency electrician page explains how this changes after storm damage.
A panel replacement is commonly done within a working day, with the power off for part of it. A service upgrade adds PSEG Long Island’s disconnect and reconnect, plus the inspection, so the outage is scheduled and the whole process runs longer on the calendar than the hours of actual work. We give you the plan before the day of the work. The sequence is in how a PSEG Long Island service upgrade works.
A panel replacement swaps the box and breakers inside your home. A subpanel is a smaller second box wired off the main one, typically serving a garage, workshop or addition. A service upgrade changes the incoming capacity, meaning the meter, cable and weatherhead, and involves PSEG Long Island. Which one you need depends on whether the limit is space, capacity or both. See panel, subpanel or service upgrade and our service upgrade page.
Not always. A house with gas heat and cooking can live comfortably on 100 amps. It becomes a real question when you add central air, an EV charger, electric heat, a heat-pump system or an addition. We calculate your actual load before recommending an upgrade, and the reasoning is in do you need 200-amp service.
It depends on which piece failed. If PSEG Long Island’s drop or meter is damaged, that side is theirs. If the weatherhead, mast, entrance cable or meter pan is damaged, those belong to the homeowner and need an electrician and often a permit. See storm-damaged service wires: who pays for how to tell, and our emergency electrician page for what to do first.
Think of the meter as the dividing line. On the street side, PSEG Long Island owns the poles and lines, the transformer, the drop to your house and the meter. On the house side, you own the weatherhead, the cable down to the meter pan, the pan, the panel and every circuit inside, which makes that part an electrician’s job. It is not always clear from the ground where one ends, so see who fixes what before you phone the wrong party.
EV charger installation
Yes. A shared lot brings extra decisions: how to split power between cars, whether chargers are networked for billing, pedestal or wall mounting, and what the utility needs to hear about it. PSEG Long Island has business programs that may offset some cost. Our commercial electrician page describes how we approach it.
Not realistically. DC fast units are built for commercial sites and draw far more power than a house service supplies, normally from three-phase equipment arranged with the utility. At home, Level 2 is the practical ceiling, and it refills a car overnight.
Start with the car. Check how fast it can accept charge, because a charger faster than the car’s onboard limit adds cost without adding speed. Then match the charger’s amperage to a circuit that is sized about 25 percent higher, and check whether the model is on PSEG Long Island’s rebate list before you buy it. We are happy to confirm all three before you order.
Usually with written approval from the board or landlord. Boards generally want a load estimate, an installation plan and proof of insurance before they agree. We can prepare the electrical details for the application. Where the building has shared metering, the work also involves how the charger’s power is billed.
There is no reliable Long Island figure we would quote. A charger is an amenity that many buyers of electric vehicles now look for, and a permitted, inspected installation is easier to sell than an unpermitted one. Whether it moves an appraisal is up to the appraiser.
The federal credit no longer applies to a home charger put into service after June 30, 2026, so any article still promoting it is stale. On the utility side, PSEG Long Island has run a rebate on qualifying Level 2 models, and which model you buy can decide whether you qualify. Look at their current program page before you purchase, and use our PSEG Long Island EV charger rebate guide as a checklist. Tax questions belong with your tax professional.
Most do not need it to charge. Wi-Fi is used for app controls, scheduling, usage reports and software updates, and some utility programs may require a connected charger. If your garage has a weak signal, tell us before we mount the unit, because the position affects the connection.
Yes, when the charger sits on its own correctly sized circuit, the connections are tight, and the work has been inspected. Trouble comes from shortcuts: extension cords, adapters, shared circuits and old outlets. Stop charging if a plug or outlet feels hot, smells or looks discolored, and have the circuit tested before you use it again.
When the panel has room and the run is short, it is often a single visit. A long run, a full panel, or a service upgrade stretches that, and the inspection is scheduled separately. We tell you the sequence at the start, so the date on which you can plug in is not a surprise.
Pick the outlet if you might change cars or chargers, since swapping a plug-in unit takes a minute. Pick hardwired if you want the highest charging rate and a tidier look outdoors, which means a 60-amp circuit feeding a 48-amp unit, provided the car and panel can take it. The full trade-off is laid out in NEMA 14-50 outlet or hardwired EV charger.
Either works. The garage is usually shorter, drier and cheaper, since the run from the panel is shorter. Outside is the better choice when the car parks in the driveway, and it needs a weather-rated enclosure and the right protection. We choose the spot by where the cable reaches the charge port, not only by where the panel is.
Sometimes. A house with gas heat and cooking often has the room. A house with electric dryer, electric heat, an air conditioner and a full panel might not. We calculate your load before we quote. If it falls short, the answers are a panel replacement, a service upgrade, or a load management device where your inspection agency accepts one.
In most cases yes, because the charger circuit is new wiring. Permits and inspections run through the town or village, and a private inspection agency approved by the town normally does the inspection. Hempstead will not let new wiring be used until the certificate of compliance is issued. We handle the paperwork where a permit is required.
You can buy one yourself, but a new 240-volt circuit is new wiring. In Nassau that means a permit where your town requires it and an inspection before you use it, and some manufacturers and rebate programs require a licensed installer. A wrong breaker size or a loose terminal on a circuit that runs for hours is the classic cause of heat at the outlet. This is a job to leave to a licensed electrician.
A licensed electrician does the wiring, and in Nassau that means the electrician holds the license that covers your town or village. Some charger brands refer you to installers, but the job is still ordinary electrical work. We install Level 2 chargers and NEMA 14-50 outlets for Nassau homes and businesses and can obtain the permit where one is required.
The price depends mostly on the run from your panel to the charger, whether the panel has room, and whether you choose an outlet or a hardwired unit. A short run from a panel with space is the easy end. A long run through finished walls, or a panel that needs replacing, is the other. The charger is bought separately, and permit and inspection fees add to the total. We quote in writing after we look at your panel.
There are two ways. Level 1 uses a standard 120-volt outlet and adds only a few miles of range an hour. Level 2 uses a dedicated 240-volt circuit, either a NEMA 14-50 outlet with a plug-in charger or a hardwired wall unit, and brings most cars to full overnight. Most owners who drive daily choose Level 2. Our EV charger installation page walks through the options.
Commercial electrical work
Often, yes. Panel changes, outages and noisy work can be scheduled for evenings or weekends so the business keeps running. Tell us your hours, your busiest days and any equipment that cannot lose power, and we plan the work around them.
A private inspection agency the town has approved does the electrical inspection, as for homes. The Nassau County Fire Marshal’s office separately handles fire alarm and emergency lighting. Emergency lights must run for at least 90 minutes, and emergency generators must pick up the load within 10 seconds, with testing done annually.
Yes for a commercial service, and for any service of 400 amps and up. The shortcut PSEG Long Island offers for residential upgrades up to 200 amps does not cover commercial work. Plan for the load letter early, because it affects the schedule. Our guide to load letters and the Fire Marshal for a build-out explains the sequence.
Call before you sign a lease or start a build-out, when you add equipment that draws heavy power, when breakers trip during busy hours, when emergency lights or exit signs fail, or when you plan a new sign, kitchen or charging station. Fixing a weak point on your schedule is cheaper than losing a Friday lunch rush to a dead panel.
Look for someone who asks about your hours, your lease, your equipment list and your landlord before they give a price. Then check the license for your town, ask who files the permit, and ask what they know about your inspection route. A reliable commercial electrician plans around your business day. See our commercial electrician page.
Often yes, if they hold the right license for the town and have the experience. The licensing is by municipality, not by building type, but the skills differ. A residential electrician may be unfamiliar with load letters and fire-safety systems, and a commercial electrician may be less familiar with older houses and their wiring. Ask about experience with your kind of building.
Residential electricians work on houses, commercial electricians work on shops, offices, restaurants and similar buildings, and industrial electricians work on factories and heavy equipment. The difference is mostly in the systems: commercial work leans on three-phase power, conduit and larger services, while industrial work adds motors and process controls. Many contractors cover residential and commercial, and we do both.
A commercial electrician works on the electrical systems of businesses and larger buildings: service equipment, panels, lighting, power for equipment, emergency and exit lighting, tenant build-outs and the controls that go with them. The work is bigger in scale than a house, uses heavier wiring methods, and is tied to business-specific rules such as the Fire Marshal and PSEG Long Island’s load letter.
Low-voltage, security cameras and intercoms
Yes, it is the cheapest time to do it. Running cable before the drywall goes up avoids cutting walls later, and it lets you pick camera, access point and speaker locations deliberately. Tell us the layout while the framing is still open.
Frequently, yes. State law treats the installation of security and fire alarm systems as a licensed trade, with the license issued by the Department of State, and a camera or door-entry system that helps detect or respond to a break-in can be counted as one. We work under the New York license for security and alarm installation. The legal background is explained in do security cameras need a license in New York.
Low-voltage wiring is the cabling that moves data, sound and video, plus the small amounts of power that cameras and intercoms need, instead of full household current. Think Ethernet, speaker runs, cameras, door intercoms and access control. It is installed differently from line-voltage wiring and is usually run before the walls are closed. See our low-voltage wiring page.
Permits, inspections and local rules
No. The Rockaways are in Queens, so electrical work there follows New York City’s Department of Buildings rules and Con Edison, not Nassau’s town licensing and PSEG Long Island’s process. We follow the process for the address.
They can. Where a property sits in a mapped flood hazard area in the Town of Hempstead, new or replacement electrical equipment has to be raised two feet above the base flood elevation, or built so that water cannot reach it (Hempstead flood ordinance). Whether swapping a panel in the same spot counts is the Building Department’s call, which is why our first step is looking up the flood map.
The state’s 2025 Uniform Code took effect on December 31, 2025 and brought in the 2023 National Electrical Code. For homeowners, the visible effects are more ground-fault and arc-fault protection where circuits are new or altered, surge protection with a new panel or service, and an outdoor emergency disconnect on many service replacements. Wiring you leave alone is generally not required to be brought up to date.
A private inspection agency approved by your town. The owner or the electrician arranges it, and the cost is often separate from the permit fee. In Freeport, for example, the village permit does not cover the agency’s inspection fee. After the inspection passes, the certificate of compliance is issued.
No. The county’s own Consumer Affairs office says electricians are licensed by the cities, towns and villages. In practice that means three layers: the licensing board of Hempstead, North Hempstead or Oyster Bay, any additional village step, and the inspection by a private agency the town has approved.
Usually yes for new wiring, new circuits, panels and service changes, though the rules differ by town and village. Small like-for-like repairs may not need one. A question that costs nothing to ask is whether your town’s building department wants a permit for the job, and we ask it before we quote.
