What we install
Commercial breaker panels, distribution panels, and subpanels sized for your actual load. Feeder circuits, breaker replacements, and torque-checked connections that stay tight. Panel schedules that match real equipment, grounding corrections, and disconnects where code requires them.
Service upgrades
When your building needs more amperage coming in from the utility, we handle the full upgrade. Coordination with PSEG Long Island, Con Edison, or National Grid. New service equipment, proper bonding, and capacity planning that grows with your business.
Load calculations
We size panels and circuits based on what you actually run, not guesses. Dedicated circuits for equipment that demands clean power. Balanced loads across phases so nothing gets overworked.
Tenant fit-outs
New tenants need new circuits, new disconnects, new labeling. We handle the electrical rework, get it inspected, and hand you a clean panel schedule so the next tenant knows what's what.
Code and compliance
Every panel we touch meets current code. Proper grounding, bonding, breaker sizing, and circuit protection. We work to what the inspector expects, so you pass the first time.

Breakers tripping
Circuits overload under normal load. We rebalance phases, add capacity, and install proper breaker protection so equipment runs without nuisance trips.

Old panels run out of breaker slots fast. We upgrade to larger panels or add subpanels so you have room for new equipment and tenant upgrades.
Flickering lights
Heavy machinery causes a voltage sag. We install dedicated circuits, balance loads, and upgrade service capacity to keep lights steady.
Inspection failures
Old panels and improper bonding fail code inspections. We bring everything up to current standards so you pass the first time.

Complete scope
What's included in a panel upgrade
We handle the full upgrade from assessment to final inspection. Load
calculations, panel sizing, breaker installation, grounding corrections, and
clean labeling so you know exactly what's running where.
A panel upgrade includes removing the existing panel, installing a higher-capacity breaker system, updating grounding and bonding, organizing circuits, and ensuring full code compliance to safely support modern electrical demands.
Common questions
Find answers to common questions about electrical repairs and service calls.
Most panel upgrades take one to three days, depending on the scope and whether utility work is needed. We coordinate timing to minimize your downtime and keep your business running.
A panel upgrade adds breaker space and reorganizes circuits. A service upgrade brings more amperage from the utility when your building needs more total power. We assess your load and recommend what fits your needs.
We plan the work to keep critical circuits live when possible. For full service upgrades, there will be a brief outage during the utility switchover. We schedule this at your convenience and communicate every step.
Old panels often fail inspections and create safety risks. We replace or upgrade them to the current code, handle all bonding and grounding corrections, and get you a clean inspection sign-off.
Yes. We manage the full coordination with PSEG Long Island, Con Edison, and National Grid for service upgrades, including applications, inspections, and the utility work itself.

Know the difference
Panel upgrade versus service upgrade
Both solve capacity problems, but they work differently. Understanding
which you need saves time and money.
Panel upgrade
Replaces or upgrades the breaker panel
itself. Adds breaker space, rebalances
loads, fixes old equipment, improves
circuit organization. No utility work
needed.
Service upgrade
Brings more amperage from the utility
to your building. Requires a new service
entrance, a new meter, a new main panel, and utility coordination. Needed when your total building load exceeds the current service capacity.
