Electrical Panel Upgrades on Long Island
Your electrical panel is the backbone of every modern home upgrade — EV chargers, central AC, finished basements, heat pumps, and solar all depend on it. This is our complete, electrician-led guide to panel and service upgrades on Long Island.
When you need a panel upgrade
Most Long Island homes built before the 1990s run 100-amp service or older fused panels. If you're adding major loads, seeing repeated tripping, or you have a Federal Pacific or Zinsco panel, it's time for an assessment.
What a 200-amp upgrade includes
A proper upgrade replaces the panel, meter pan, service-entrance cable, and grounding system, and coordinates the PSEG Long Island cut-in. Current code also requires whole-home surge protection.
Permits, inspection & PSEG
Panel and service work requires a town electrical permit, a third-party electrical inspection, and PSEG coordination for the disconnect/reconnect. We handle all of it.
