How much does an electrical panel upgrade cost?

Replace panel (same amperage): $1,500-$3,000. Upgrade 100A to 200A (most common): $2,000-$4,000. Upgrade 60A to 200A (older home, new service entrance): $3,000-$6,000. Add a subpanel: $500-$1,500. Full service upgrade (new cable, weatherhead, meter, panel): $3,000-$6,000. Cost components: panel $200-$500, service entrance cable $200-$500, labor $1,000-$2,500, permit $100-$300. The utility disconnect/reconnect is usually free but requires 1-2 weeks scheduling. Do I need to upgrade from 100 to 200 amps?

Do I need to upgrade from 100 to 200 amps?

Likely yes if you're adding any major electrical load: EV charger (40-50A), central AC (30-60A), hot tub (50-60A), electric range (40-50A), or electric dryer (30A). A 100A panel typically can't support modern loads plus these additions. You also need to upgrade if: you're finishing a basement or adding rooms, converting from gas to electric appliances, installing solar panels, or your panel is frequently tripping breakers. A 200A panel is the current standard and handles virtually any residential need. Cost: $2,000-$4,000 for a 100A to 200A upgrade. How do I know if my electrical panel is dangerous?

How do I know if my electrical panel is dangerous?

Dangerous panels to replace immediately: Federal Pacific Electric (FPE) Stab-Lok panels (documented failure to trip, fire risk) and Zinsco/GTE-Sylvania panels (breakers melt to the bus bar). Warning signs: scorched wires or melted plastic, burning smell near the panel, breakers that won't stay reset, warm outlets, lights that dim when appliances turn on, double-tapped breakers (two wires under one breaker), and fuse boxes with oversized fuses. If you have any of these signs, have a licensed electrician inspect your panel immediately.

Electrical Panel Upgrade Guide: Cost, When to Upgrade & 200 Amp Service

Why Upgrade?

Safety: Older panels (especially those installed before 1990) may have outdated components that pose fire and shock risks. Known hazardous panels: Federal Pacific Electric (FPE) Stab-Lok panels: documented failure to trip during overloads (fire risk). If you have an FPE panel, replace it immediately. Zinsco/GTE-Sylvania: breakers that melt to the bus bar and fail to trip. If identified, replace immediately. Fuse boxes: not inherently dangerous if properly fused, but limited capacity and outdated. Any panel with signs of overheating: scorched wires, melted plastic, burnt smell, or discolored breakers.

Capacity: Modern homes draw more power than ever. Adding major loads requires panel capacity: central AC (30-60A), electric vehicle charger (40-50A), electric water heater (30A), electric range (40-50A), electric dryer (30A), hot tub (50-60A), home workshop (20-60A), and solar panel system. A 100A panel (common in homes built before 1980) often can't support modern loads. A 200A panel is the current standard and handles virtually any residential need.

Home renovation: Many jurisdictions require a panel upgrade when doing a major renovation, adding square footage, or converting a garage or basement. Insurance: some insurance companies require panel upgrades (especially replacing FPE or Zinsco panels) or charge higher premiums for outdated panels. Real estate: an outdated panel can be a red flag for buyers and may need to be upgraded as a condition of sale.

Cost

By upgrade type: Replace panel (same amperage, e.g., swap a 200A panel for a new 200A panel): $1,500-$3,000. Upgrade 100A to 200A (most common upgrade): $2,000-$4,000. Upgrade 60A to 200A (older home, requires new service entrance): $3,000-$6,000. Add a subpanel (to extend capacity to a garage, workshop, or addition): $500-$1,500. Full service upgrade (new service entrance cable, weatherhead, meter, and panel): $3,000-$6,000.

Cost components: New panel (200A, 30-40 spaces): $200-$500. Main breaker: included with panel. New breakers: $5-$20 each (standard), $30-$50 (AFCI/GFCI). Service entrance cable (from meter to panel): $200-$500. Weatherhead and mast: $100-$300. Meter base (if required by utility): $100-$300. Labor: $1,000-$2,500 (4-10 hours). Permit: $100-$300. Inspection: included with permit.

Utility coordination: The utility company must disconnect and reconnect the service (often at no charge, but scheduling is required). In some areas, the utility replaces the meter and connects to the new service entrance. This coordination can add time (1-2 weeks for scheduling).

Signs You Need an Upgrade

Your panel has: A fuse box instead of breakers. Federal Pacific Electric (FPE) or Zinsco branding (check the panel door and breaker labels). Less than 100A service (check the main breaker — if it says 60A or 100A). Fewer than 20 spaces (you're out of room for new circuits). Breakers that trip frequently (even after reducing load on the circuit). Evidence of overheating: scorch marks, melted plastic, burnt smell. Double-tapped breakers (two wires under one breaker — a code violation).

You're planning: Adding an EV charger (40-50A). Adding central AC. Adding a hot tub or pool. Major kitchen remodel (new appliances). Finishing a basement or adding a room. Installing solar panels (may require a new or upgraded panel for the inverter connection). Converting from gas to electric (heat pump, induction range, electric water heater).

Your experience includes: Lights dim or flicker when large appliances turn on. Outlets that feel warm. Extension cord reliance (not enough outlets on circuits). Breakers that won't stay reset. Burning smell near the panel.

Installation Process

Step 1 — Assessment: A licensed electrician inspects your current panel, service entrance, and meter. They determine: the current amperage, the condition of the panel and wiring, the loads you want to add, and whether the service entrance and meter need to be upgraded (not just the panel). They provide a quote and timeline.

Step 2 — Permits: An electrical permit is required. The electrician typically pulls the permit. The utility is notified and coordinates the disconnect/reconnect.

Step 3 — Installation: The utility disconnects power (or the electrician disconnects at the meter with utility coordination). The old panel is removed. If upgrading amperage: the service entrance cable (from meter to panel) is replaced with a larger gauge. The meter base may be replaced. The weatherhead and mast may be replaced. The new panel is mounted. All circuits are reconnected to new breakers. New circuits are added as needed. The panel is labeled (every breaker must be clearly labeled per code). Grounding and bonding are verified and updated to current code.

Step 4 — Inspection: The electrical inspector verifies: proper installation, grounding and bonding, breaker sizing, wire gauge matching, labeling, and code compliance. After passing inspection, the utility reconnects power.

Timeline: 1-2 days for the electrical work. 1-2 weeks for utility scheduling (the main variable). Total project: 1-3 weeks including scheduling and inspection.

What to Expect

Power outage: Your home will be without power for 4-8 hours during the panel swap. Plan accordingly: charge devices, avoid opening the refrigerator, and arrange alternatives if needed. If you work from home, plan for a day at a coffee shop or coworking space.

After the upgrade: Your new panel will have labeled breakers (every circuit identified). AFCI and GFCI breakers may be installed where required by current code. The panel will have room for future additions (30-40 spaces is standard for 200A). You can now safely add the loads you need (EV charger, AC, etc.).

Panel brands: Square D (Schneider Electric): the most popular residential panel. Reliable and widely available. Eaton: excellent quality, good breaker design. Siemens: good quality, widely available. Leviton: newer entrant, good smart panel options.

Smart panels: Newer panels (Span, Leviton Smart Panel) offer circuit-level monitoring, remote control, and integration with solar and battery storage. These are premium options ($3,000-$6,000 for the panel alone) but provide valuable energy management features for homes with solar, batteries, or EVs.
