Electrical Panel Upgrades in Brooklyn, NY

Brooklyn House Rewiring upgrades outdated fuse boxes and undersized panels to modern 200-amp breaker panels built for the way homes use power today. A service or panel upgrade replaces an old 60 or 100-amp fuse box, or a failing breaker panel, with a properly sized service that can carry central HVAC, electric appliances, and an EV charger without tripping or overheating. We handle the load calculation, the panel and service equipment, the grounding and bonding, and the coordination with the utility, all under a NYC electrical permit inspected and signed off by the proper authority. A right-sized panel is the backbone every other electrical upgrade in the house depends on.

From Fuse Box to 200-Amp Breaker Panel

Older Brooklyn homes were wired for a fraction of the load a modern household draws, and a 60 or 100-amp fuse box simply cannot keep up with central air, an electric range, a heat pump, and everything else running at once. We replace the old service with a 200-amp breaker panel that has the capacity and the open circuit spaces to run the whole house comfortably. Breakers are also safer and easier to live with than fuses, because they reset instead of needing replacement and they support modern GFCI and AFCI protection. The upgrade turns a stretched, tripping service into one with room to spare.

Load Calculation Done Right

Sizing a panel is not guesswork, it is a load calculation that adds up the home's heating, cooling, kitchen, laundry, and any EV or workshop loads to determine the service required. We run that calculation before quoting so the panel we install matches how your home actually draws power, with headroom for what you plan to add. Undersizing leads to nuisance tripping, and oversizing wastes money, so getting the number right is the core of the job. That calculation is also what the permit and inspection are checked against.

Grounding, Bonding, and Safety Devices

A panel upgrade is the right moment to bring the home's grounding and bonding up to current code, because a modern panel is only as safe as its ground. We install or verify the grounding electrode system, bond the water and gas piping where required, and populate the panel with AFCI and GFCI breakers on the circuits code now demands. Surge protection can be added at the panel to shield the whole house from utility and lightning surges. When we finish, the panel is not just bigger, it is safer at every connection.

Utility Coordination, Permits, and Inspection

Replacing the service means coordinating a power shutdown and, on service upgrades, working with the utility on the meter and service entrance. We file the NYC electrical permit, schedule the disconnect and reconnect, perform the work as a licensed master electrician, and see it through inspection and sign-off. You get the upgrade done on a planned schedule with minimal downtime and full documentation. Nothing is energized until it has been done correctly and legitimately.

Frequently Asked

How do I know if I need a panel upgrade?
Common signs are a fuse box or a panel below 150 amps, breakers that trip when appliances run together, no open spaces left for new circuits, a warm or buzzing panel, or plans to add central air, an EV charger, or an electric range. We run a load calculation and inspect the existing service to confirm whether an upgrade is genuinely needed before recommending one.
How long does a panel upgrade take and will my power be off?
Most residential panel or service upgrades are completed in a single day. Power is off for part of that day while we swap the equipment, and we schedule the shutdown and any utility disconnect in advance so you can plan around it. By evening the home is back on a modern, inspected panel.
Do I need a 200-amp service or is 100 amps enough?
It depends on your load calculation. A small home with gas heat and cooking and no EV can sometimes run on 100 or 150 amps, but any home adding central HVAC, electric appliances, or EV charging generally needs 200 amps. We size the service to your actual and planned loads rather than defaulting to one answer.
Is a permit required to replace an electrical panel in Brooklyn?
Yes. Replacing a panel or service in NYC requires an electrical permit, must be performed by a licensed master electrician, and has to be inspected and signed off. We file the permit and carry the job through inspection so the work is documented, code-compliant, and safe at resale.
