200 Amp Service Upgrade

A 100-amp electrical panel was standard for most homes built before the 1990s. At the time, households ran fewer appliances, had no electric vehicle chargers, and relied on smaller HVAC systems. Today, the average American home draws significantly more power — central air conditioning alone can pull 30-50 amps during peak summer months in South Florida.

Upgrading from 100 amps to 200 amps is not simply swapping out a panel box. The entire service entrance — including the meter base, the service entrance cable from the weatherhead to the panel, and often the grounding system — must be upgraded to handle the higher amperage. This is a comprehensive project that requires coordination between your electrician, the local utility company (typically FPL in South Florida), and the municipal building department for permits and inspections.

Several scenarios make a panel upgrade not just advisable but mandatory. First, Florida insurance companies increasingly require homes with panels older than 30 years to be upgraded before coverage will be issued or renewed. Certain legacy panel brands — including Federal Pacific, Zinsco, and Challenger — are considered fire hazards and are flagged by inspectors and underwriters alike.

Second, if you are adding a Level 2 EV charger (which typically requires a dedicated circuit), a pool heater, a tankless water heater, or a home standby generator, your existing 100-amp service may not have the capacity to safely accommodate the additional load. An NEC Article 220 load calculation performed by a licensed electrician will determine whether your current panel can handle the addition or whether an upgrade is required.

Third, if you are selling your home, a pre-sale electrical inspection may reveal that your panel does not meet current code requirements. Upgrading proactively can prevent deal-killing inspection findings and increase your property value significantly according to Florida real estate appraisers.

A professional 200-amp panel upgrade typically takes 6-10 hours for a straightforward installation, though complex jobs involving service entrance relocation or extensive rewiring may extend to two days. Here is the typical timeline our electricians follow:

The crew arrives and verifies the permit is posted. FPL pulls the meter to disconnect power — this step must be scheduled in advance through a utility work request. The old panel, breakers, and service entrance cable are removed. A new 200-amp rated meter base is installed (if required by the utility), followed by new service entrance cable rated for 200 amps. The new panel — typically a 200-amp, 40-space main breaker panel — is mounted, and all existing branch circuits are transferred to the new panel with properly sized breakers.

Arc-fault circuit interrupters (AFCIs) are installed on all bedroom circuits as required by NEC 210.12, and ground-fault circuit interrupters (GFCIs) are installed on kitchen, bathroom, garage, and outdoor circuits per NEC 210.8. Whole-home surge protection is installed at the panel. After the installation is complete, a municipal electrical inspector visits the site to verify code compliance before FPL reconnects the meter.

Panel upgrade pricing in South Florida varies based on several factors: the condition of the existing electrical infrastructure, whether the meter base needs replacement, whether additional circuits are being added during the upgrade, and the specific municipality's permit fees.

A standard 100A to 200A panel upgrade in Miami-Dade or Broward County varies in cost depending on specific property requirements, including the panel, breakers, labor, permit fees, and the utility coordination fee. This does not include any additional circuit installations, whole-home rewiring, or generator transfer switch pre-wiring that homeowners often choose to bundle with their upgrade.

Beware of extremely low quotes — they may not include permit fees (which vary depending on the municipality), utility coordination fees, or the mandatory inspection. A proper panel upgrade with all permits and inspections is a code-compliant, insurable improvement. A cut-rate job without permits is a liability that can void your homeowner's insurance and create legal problems when you sell.

Not all electricians are equally qualified for panel upgrades. In Florida, only a licensed Electrical Contractor (EC license) can pull permits for and perform panel upgrades — a journeyman or registered electrician working independently cannot legally perform this work. Always verify your electrician's license through the Florida DBPR license verification portal.

Ask these questions before hiring: Does the quote include all permit fees and the utility coordination fee? Will they handle the FPL meter pull request, or is that your responsibility? Do they install whole-home surge protection as part of the upgrade? What brand and model panel do they install? How many spaces does the new panel have? A quality contractor will install a 40-space or 42-space panel to allow room for future circuit additions — a 20-space or 30-space panel saves a small amount upfront but limits your options later.

Check their insurance — a proper electrical contractor carries general liability insurance and workers' compensation coverage. Ask for a certificate of insurance. Finally, get everything in writing: the scope of work, the timeline, the total price, and the warranty terms.
