Electrical Panel Replacement Services

Reviewed 2026-07-30

Electrical panel replacement removes an outdated, undersized, or unsafe panel and installs a modern one. A new panel adds enough amperage and current breaker protection, and it replaces known fire-risk brands that cause nuisance trips.

Symptoms electrical panel replacement solves

  • Breakers trip repeatedly even with normal household loads
  • The panel is a Federal Pacific Stab-Lok, Zinsco, or Challenger brand
  • The panel is rated 60 or 100 amps and can't support modern appliance and EV loads
  • Double-tapped breakers or visible rust, scorching or melted plastic inside the panel
  • You're adding a hot tub, EV charger, or major addition that exceeds current capacity
  • The panel buzzes, hums, or feels warm to the touch from outside the cover
  • Your insurance company is requiring an upgrade or won't renew coverage

When to book electrical panel replacement

  • Before an insurer's non-renewal deadline if a hazard-brand panel is flagged
  • Before permitting any addition, EV charger install, or major appliance upgrade
  • As soon as you notice heat, buzzing, or repeated nuisance tripping
  • When buying a home with a panel over 25-30 years old

What happens during electrical panel replacement

  1. Electrician performs a load calculation per NEC 220 to size the new panel correctly (typically 150-200 amps for modern homes)
  2. Permit is pulled with the local building department
  3. Utility company schedules a temporary power disconnect at the meter
  4. Old panel and breakers are removed; new panel, breakers, and grounding/bonding are installed to current code
  5. Electrician labels all circuits and reconnects power
  6. Local inspector performs a final code inspection before the job is closed out

Electrical Panel Replacement methods and approaches

Like-for-like panel swap

Replacing an existing 100-150A panel with a new one of the same capacity when wiring and service entrance are otherwise adequate. Fastest and least expensive option, typically completed in one day.

Service upgrade with panel replacement

Upgrading the electrical service (meter, mast, and panel together) to 200 amps, required when load calculations show existing capacity is insufficient for current or planned use.

Subpanel addition instead of full replacement

When the main panel has room but a specific area (garage, workshop, addition) needs more circuits, a subpanel fed from the main panel avoids a full replacement.

What drives electrical panel replacement pricing

  • New amperage rating (100A, 150A, or 200A service)
  • Whether the utility service entrance and meter also need upgrading
  • Number of circuits being transferred and relabeled
  • Permit fees, which vary by municipality
  • Panel brand and features (surge protection, smart breakers)
  • Accessibility of the existing panel location and any code-required relocation

Questions to ask your licensed electrician

  • What amperage do you recommend based on a load calculation, not a guess?
  • Is the cost quote inclusive of permit fees and the final inspection?
  • Will the utility company need to schedule a disconnect, and how long will power be off?
  • What panel brand and breaker type will you install, and are they AFCI/GFCI compatible?
  • Do you warranty the labor separately from the panel manufacturer's warranty?
  • Will you provide an updated circuit directory/labeling when finished?

Electrical Panel Replacement safety and licensing

  • Never attempt a panel replacement yourself — this work requires a licensed electrician, a permit, and coordination with the utility company to safely de-energize the service.
  • Do not use a home with a confirmed Federal Pacific Stab-Lok panel while waiting for replacement if you've observed any tripping issues; have an electrician assess urgency immediately.
  • A permit and final inspection are not optional extras — unpermitted panel work can void insurance claims and create resale problems.

Electrical Panel Replacement questions homeowners ask

How long does a panel replacement take?

Most single-panel swaps take one full day including the utility disconnect, physical swap, and reconnection. Full service upgrades with a new meter can take 1-2 days plus the permit inspection scheduling.

Will my power be off during replacement?

Yes, typically for 4-8 hours while the utility disconnects service and the electrician completes the swap. Most electricians schedule this for weekday daytime hours.

Do I need a permit for a panel replacement?

Yes, virtually every jurisdiction requires a permit and final inspection for panel work under NEC and local amendments — it's not optional and unpermitted work creates resale and insurance problems.
