Federal Pacific/Zinsco panel replacement	$2,000–$4,000	$2,800

Types of Panel Upgrades

100-Amp to 200-Amp Upgrade

This is the most common panel upgrade and the one most homeowners need. Homes built before 1980 often have 100-amp service, which isn't enough for modern electrical demands. A 200-amp upgrade doubles your capacity and is the current standard for residential construction.

Typical cost: $1,800–$3,500

This job involves replacing the panel, upgrading the meter base (usually), pulling new service entrance conductors from the meter to the panel, and re-terminating all existing circuits in the new panel. It's a full day of work for a licensed electrician.

Panel Replacement (Same Amperage)

Sometimes you don't need more capacity — you just need a panel that isn't a fire hazard. Common scenarios:

• Federal Pacific panels: Known fire risk. Insurance companies increasingly refuse to cover homes with FPE panels.
• Zinsco/Sylvania panels: Breakers known to melt and fail to trip. Another insurance red flag.
• Outdated panels with no space: Full panel with no room for additional circuits, but 200A service is adequate.
• Corrosion or physical damage: Panels in flood-prone areas, coastal environments, or poorly weatherproofed locations.

Typical cost: $1,500–$2,800 (less than an amp upgrade because service entrance conductors don't need replacement)

Subpanel Installation

A subpanel is a secondary panel fed from the main panel. It's the right solution when you need circuits in a specific location — garage, workshop, addition, or basement — but don't need to upgrade your main service.

Typical cost: $800–$2,000 depending on amperage, distance from main panel, and number of circuits.

200-Amp to 400-Amp Upgrade

Large homes with electric heating, EV charging for multiple vehicles, pools, workshops, and home additions may exceed 200-amp capacity. A 400-amp service is becoming more common in new luxury construction.

Typical cost: $4,000–$8,000 — this is a major project involving utility coordination, new service entrance, and often a CT (current transformer) meter cabinet.

What's Included in a Standard 200-Amp Upgrade

Here's what should be included in a professional panel upgrade quote:

• New 200-amp panel with 30–40 circuit breaker spaces (Square D, Siemens, or Eaton are the standard choices)
• All new circuit breakers (your old breakers won't fit the new panel — and shouldn't be reused anyway)
• New meter base (usually required for amp upgrade; sometimes the utility provides this)
• New service entrance conductors from meter to panel (typically 4/0 aluminum or 2/0 copper)
• New grounding system — ground rods, grounding electrode conductor, bonding per current code
• Re-termination of all existing circuits in the new panel
• Proper circuit labeling
• Permit and inspection
• Utility coordination — scheduling the disconnect and reconnect with the power company

What Drives the Cost Up

1. Meter Base Location

If the meter is on the opposite side of the house from the panel, the service entrance conductor run can add $300–$1,000 in materials and labor. Some upgrades require relocating the panel to be adjacent to the meter, which adds significantly to the cost.

2. Underground vs Overhead Service

Overhead service (power lines to your house) is straightforward for the utility to disconnect and reconnect. Underground service can involve trenching, conduit work, and longer conductor runs. Add $500–$2,000 for underground service complications.

3. Code Upgrades Beyond the Panel

When you pull a permit for a panel upgrade, the inspector may flag other code issues that need to be addressed:

• AFCI breakers: Current code requires arc-fault circuit interrupter breakers for most living spaces. Retrofitting AFCI on existing circuits adds $30–$50 per circuit.
• GFCI protection: Kitchens, bathrooms, garages, and outdoor circuits need GFCI protection if they don't already have it.
• Grounding upgrades: Older homes may have inadequate grounding that needs to be brought to current code.
• Bonding: Gas lines, water pipes, and CSST gas piping all have specific bonding requirements.

These code items can add $300–$1,500 to the project. A good electrician will identify these during the estimate, not surprise you on inspection day.

4. Panel Relocation

Moving the panel to a new location — from a bedroom closet (not allowed by current code) to a garage or utility room — is a significant add-on. Expect $1,000–$3,000 extra for panel relocation depending on the distance and complexity.

5. Asbestos or Lead Paint

In homes built before 1980, the area around the panel may have asbestos-containing materials or lead paint. Disturbing these requires special handling — and potentially licensed abatement. This can add $500–$2,000 to the project and is something you don't want to discover mid-job.

Signs You Need a Panel Upgrade

Not sure if you actually need a panel upgrade? Here are the clear indicators:

• Breakers trip frequently — especially when running multiple appliances. This means your circuits are at capacity.
• You're adding major loads — EV charger (40–50A), heat pump (30–60A), hot tub (50A), workshop equipment, home addition
• You have a Federal Pacific or Zinsco panel — replace it regardless of capacity. These are documented safety hazards.
• Your panel uses fuses instead of breakers — fuse panels are outdated, hard to get parts for, and most insurance companies want them replaced
• Flickering lights when appliances kick on — sign of an overloaded panel or loose connections
• Double-tapped breakers — two wires on one breaker is a code violation and fire risk
• You're selling your home — home inspectors flag outdated panels, and buyers' insurance may require upgrades before closing
• Your insurance requires it — many carriers now require 200A service and refuse to insure FPE/Zinsco panels

The Upgrade Process Step by Step

1. Initial Assessment (Your Electrician's Job)

A qualified electrician should inspect the existing panel, meter base, service entrance, and grounding. They should also do a load calculation — adding up your current and planned electrical loads to confirm 200A is sufficient (or if you need 400A).

2. Permit and Utility Coordination

Your electrician pulls the permit (typically $75–$250) and coordinates with the utility company. The utility needs to disconnect power for the upgrade and reconnect after. This scheduling can take 1–3 weeks depending on the utility.

3. Installation Day

Typical timeline for a 100A to 200A upgrade:

• 7:00 AM: Utility disconnects power at the meter
• 7:30 AM: Remove old meter base and panel
• 8:00–10:00 AM: Install new meter base, run new service entrance conductors
• 10:00 AM–2:00 PM: Install new panel, re-terminate all circuits, install new grounding
• 2:00–3:00 PM: Testing, labeling, cleanup
• 3:00–4:00 PM: Utility reconnects power, electrician verifies everything works

4. Inspection

The building department inspects the work — usually within 1–5 business days of completion. The inspector checks the panel installation, grounding, conductor sizing, breaker compatibility, and code compliance. If anything fails, your electrician fixes it and reschedules.

For Electricians: How to Price Panel Upgrades

Panel upgrades are one of the highest-margin residential electrical jobs. Here's your real cost breakdown:

Material Costs (Your Cost)

Material	Cost
200A panel (Square D Homeline 40-space)	$150–$250
Circuit breakers (20–30 breakers)	$150–$400
200A meter base	$100–$200
Service entrance conductors (4/0 Al, 10–20ft)	$80–$200
Grounding materials (rods, clamps, wire)	$50–$100
Miscellaneous (connectors, bushings, straps, tape)	$30–$75
Permit fee	$75–$250
Total Materials	$635–$1,475

Labor

A standard 200A upgrade takes one electrician 6–10 hours. At your internal labor cost of $40–$60/hour (including burden), that's $240–$600 in labor cost.

Total Cost to You: $875–$2,075

With a target margin of 40–50%, your selling price should be $1,800–$3,500. That's $900–$1,500 gross profit per panel upgrade.

At 2–3 panel upgrades per week (very achievable in most markets given EV and heat pump demand), that's $1,800–$4,500/week in gross profit from panel work alone.

Frequently Asked Questions

How long does a panel upgrade take?

The actual installation takes 6–10 hours (one full day). The overall process including permits, utility coordination, and inspection spans 1–3 weeks.

Do I need a panel upgrade for an EV charger?

Maybe not. A Level 2 EV charger typically needs a 40–50 amp circuit. If you have a 200A panel with available space and your load calculation shows sufficient capacity, you can add the circuit without upgrading. If you have a 100A panel or your 200A panel is already loaded, you'll likely need the upgrade first.

Will a panel upgrade increase my home's value?

Yes. Upgrading from 100A to 200A typically adds $2,000–$5,000 in home value — roughly 1–2x what you pay for the upgrade. It also eliminates a common home inspection objection that can kill deals or lead to price negotiations.

Can I upgrade the panel myself?

No. Panel upgrades require a licensed electrician, a permit, utility coordination, and inspection in virtually every jurisdiction. Working in the panel without utility disconnection can kill you — main service entrance conductors are always live even when the main breaker is off.

How do I choose between 200A and 400A?

For most homes, 200A is sufficient. Consider 400A if you have: all-electric heating and cooling, multiple EV chargers, a large workshop, pool and hot tub, and a home over 4,000 sq ft. Your electrician should do a load calculation to determine the right size.
