Electrical Panel Upgrade Cost in NJ: What to Expect

Most New Jersey homeowners pay $2,000–$4,500 to upgrade an electrical panel to 200 amps. A straightforward 100-amp panel swap can land near $1,500; a service upgrade that requires a new mast, meter, and utility coordination can pass $6,000.

Cost by scope

Scope	Typical NJ cost
Panel replacement, same amperage (100A)	$1,300 – $2,200
Upgrade 100A to 200A	$2,000 – $4,500
Upgrade to 400A service	$4,500 – $9,000
Sub-panel addition	$900 – $2,000
Replace recalled/unsafe panel (FPE, Zinsco)	$2,200 – $4,500

Do you actually need an upgrade?

You likely do if any of these apply:

• Breakers trip when the microwave and A/C run together
• You still have a fuse box, or a Federal Pacific Stab-Lok / Zinsco panel
• You are adding an EV charger, heat pump, hot tub, or finishing a basement
• Lights dim when large appliances start
• The panel is full and there is no room for a new circuit
• You are seeing scorch marks, buzzing, or a burning smell — stop and call an electrician today

Federal Pacific and Zinsco panels are common in NJ homes built from the 1950s through the 1980s and have a documented history of breakers failing to trip. Many insurers now surcharge or decline coverage over them.

What is in the price

• Labor: 6–10 hours for a licensed electrician and helper
• Panel and breakers: $400–$1,200 depending on brand and circuit count
• Permit and inspection: $150–$400 depending on township
• Utility coordination: JCP&L, PSE&G, or Atlantic City Electric must disconnect and reconnect the service drop — usually free, but it has to be scheduled
• Grounding upgrades: new ground rods and bonding, often required to meet current code

Permits and inspections in New Jersey

Electrical service work in NJ requires a permit from your municipal construction office and an inspection by the electrical subcode official. Your contractor should pull it. Skipping the permit creates real problems at resale, and unpermitted service work is a common flag in NJ home inspections.

EV chargers and heat pumps

A Level 2 EV charger draws 40–60 amps. Add a heat pump or an induction range and a 100-amp service runs out of headroom fast. If you are planning any electrification in the next few years, upgrading to 200 amps once is cheaper than doing a partial fix now and the full upgrade later.

Choosing an electrician

Confirm the contractor holds a New Jersey Electrical Contractor license (issued by the Board of Examiners of Electrical Contractors), carries insurance, and is registered as a home improvement contractor. Get at least two written quotes; the spread on panel work is wide.
