Electrical Panel Upgrades on Long Island

Long Island living means big single-family homes, finished basements, pools and the storms that knock the power out — so 200-amp service, generators and EV chargers are the norm, not the exception. Precision Power upgrades Long Island panels to modern service, with the town permit, PSEG Long Island coordination and inspection handled.

Panel Upgrades for Long Island Homes

Long Island is suburban single-family living at scale — from Hempstead and Levittown to Huntington, Massapequa and the South Shore. Big homes, finished basements, pools and well pumps mean heavy electrical loads, and the Island's exposure to coastal storms makes whole-home standby generators less a luxury than a plan.

All of that adds up fast on an older 100- or 150-amp service, so 200-amp (and sometimes 400-amp) upgrades are the norm here. Two things are specific to the Island: your utility is PSEG Long Island, not Con Edison, and your electrical permit comes from your local town building department, not the NYC DOB.

We coordinate the PSEG Long Island disconnect/reconnect, file your town permit and manage the inspection — and size the service so a generator, pool, AC and a pair of EVs all run together without tripping.

What's Different Here

Panel Work That's Specific to Long Island

From a Massapequa generator install to a Huntington pool upgrade — here's where our local experience shows up.

Storm-Ready Generator Service

Coastal storms knock out power across the Island. We set the service, panel and transfer switch so your standby generator takes over automatically.

Heavy Suburban Loads

Pools, well pumps, central AC and EVs add up. We size 200A or 400A service with the headroom Long Island homes actually need.

PSEG-Coordinated, Town-Permitted

Your utility is PSEG Long Island and your permit is local — we handle both the PSEG coordination and the town building-department filing and inspection.

"After the last nor'easter took our power for days, we put in a standby generator. Precision Power upgraded our Massapequa panel to 200 amps, set the transfer switch and coordinated PSEG and the town. Next storm, we won't even notice."

Long Island Questions

Panel Upgrades on Long Island — FAQs

Who handles the utility for a Long Island panel upgrade?
On Long Island the utility is PSEG Long Island, not Con Edison. We coordinate the PSEG disconnect/reconnect and any service-side upgrade as part of the job.
Where does the permit come from on Long Island?
From your local town building department — Long Island is outside the NYC DOB. We file the town permit and manage the inspection for your municipality, in both Nassau and Suffolk.
Can you set my panel up for a standby generator?
Yes — it's one of the most common Long Island jobs. We size the service, install the automatic transfer switch, and wire the panel so a generator carries your home through the next outage.
Do I need 200 or 400-amp service?
Most homes are well served by 200 amps. Larger homes running a generator, pool, well pump, central AC and EVs together sometimes need 400. We confirm with a load calculation.
