PANEL UPGRADES &
SURGE PROTECTION

Most Long Island homes built before 1980 were wired for 60A or 100A service — nowhere near enough for today's loads. MJ Electric upgrades panels safely, with permits, across Nassau and Suffolk County.

200A electrical panel upgrade by MJ Electric in Huntington NY
Why It Matters

WHY YOUR LONG ISLAND HOME NEEDS A PANEL UPGRADE

Handle Modern Loads

EV chargers, HVAC systems, hot tubs, and home offices demand far more power than older panels were designed for. A 200A upgrade gives you room to grow.

🔥

Eliminate Fire Risk

Outdated fuse boxes and overloaded panels are a leading cause of residential fires. A modern breaker panel with arc fault protection dramatically reduces this risk.

🏠

Required for Home Sales

Home inspectors routinely flag 60A and 100A panels. Many insurance companies won't cover homes with fuse boxes. An upgrade protects your investment.

🔌

Enable EV Charging

A Level 2 EV charger requires a dedicated 50A circuit. If your panel doesn't have capacity, a panel upgrade is the first step — and we can bundle both.

Our Process

HOW IT WORKS

01

Free Assessment

We evaluate your current panel amperage, available slots, grounding, and whether your service entrance needs to be upgraded with PSEG LI.

02

Permit Application

We file for the required electrical permit with your Nassau or Suffolk County building department before any work begins.

03

PSEG Coordination

For service entrance upgrades, we coordinate the PSEG LI utility disconnect and reconnect — we handle all the scheduling.

04

Panel Installation

We install your new breaker panel, transfer all circuits, add whole-home surge protection, and label every breaker clearly.

05

Inspection & Sign-Off

We schedule the required inspection with the county. Once passed, your new panel is fully documented and code-compliant.

The Details

WHAT WE INSTALL & WHAT TO EXPECT

We install main breaker panels from Square D, Siemens, Eaton, and Leviton in sizes from 100A to 400A. For most Long Island homes, a 200A upgrade is the right choice — it handles everything from EV chargers to central air conditioning to a home addition without issue.

Every panel upgrade includes: proper grounding and bonding, new breakers for all existing circuits, arc fault (AFCI) and ground fault (GFCI) protection where required by current NEC code, and whole-home surge protection. We also coordinate with PSEG Long Island for any service entrance work.

The job typically takes one full day. Power is off for 4–6 hours during the swap. We work efficiently and communicate clearly about the timeline. After inspection sign-off, you'll have documentation of the completed, permitted work for your records and future buyers.
