Both Square D QO and Siemens PL are excellent, code-compliant electrical panels that Florida electricians install routinely.

Frequently Asked Questions

What electrical panels are not allowed in Florida homes?
Many Florida insurers refuse to write policies on homes with Federal Pacific Electric (FPE) Stab-Lok panels, Zinsco/Sylvania panels, and some older Challenger panels. These brands have documented breaker failure issues. If your home has one of these panels, replacement is strongly recommended — both for insurance purposes and safety.
How much does electrical panel replacement cost in Florida?
Replacing a 200-amp residential electrical panel in Florida typically costs $1,800–$3,500 all-in (panel, breakers, labor, permit). Upgrading from 100A to 200A runs $2,000–$3,800. In South Florida (Miami-Dade, Broward) expect 15–25% higher pricing than Central or North Florida.
Does replacing an electrical panel increase insurance in Florida?
Replacing a problematic panel (FPE, Zinsco) with a modern Square D or Siemens panel typically resolves the insurer's concern and may allow you to obtain coverage that was previously denied. Some insurers offer premium discounts for newer panels, though this varies by company. Get a 4-point inspection after the replacement to document the upgrade for your insurer.
