How much does a panel upgrade cost in Jacksonville?

A standard 100-amp to 200-amp panel upgrade in Jacksonville costs 1,800-3,500, including City of Jacksonville permit and JEA coordination. Upgrading from 200-amp to 400-amp service for a large Jacksonville home with whole-house generator integration runs 3,500-6,500. Generator interlock kits (without panel change) run 200-600. Emergency or after-hours upgrades carry 25-50 per hour premiums.

Do I need a permit for a panel upgrade in Jacksonville?

Yes - the City of Jacksonville requires an electrical permit for any service panel upgrade. The permit process involves a COJ electrical inspection before JEA will reconnect your meter. Reputable Jacksonville licensed electricians pull all required permits as part of their standard service. Unpermitted panel work creates fire risk, insurance exposure, and title issues at home resale. Check permits at [permits.coj.net](https://permits.coj.net).

How do I verify an electrician is licensed in Jacksonville?

Verify Florida electrical contractor license status at the [Florida DBPR license lookup](https://www.myfloridalicense.com/wl11.asp). Look for Florida Certified Electrical Contractor (EC) or Registered Electrical Contractor (ER) status. Confirm the license is active and free from disciplinary actions. Also request proof of general liability insurance and workers compensation insurance certificates before work begins.

How long does a Jacksonville panel upgrade take?

The physical installation of a panel upgrade takes 4-8 hours for a licensed Jacksonville electrician. However, the total project timeline includes City of Jacksonville electrical inspection scheduling (typically 1-3 business days) and JEA meter reconnection after inspection approval (1-3 additional business days). Plan for 2-7 days without power at the affected service entrance during the full process. Projects in Duval County typically move faster than rural St. Johns or Clay County work.

What size panel do I need for a Jacksonville home with a generator?

For most Jacksonville homes (2,000-3,000 sq ft, central HVAC, pool, EV charger, and standby generator), a 200-amp panel minimum is required; a 400-amp panel or dual 200-amp panels is recommended for whole-home backup. A generator interlock or automatic transfer switch can be added to any properly sized panel. JEA requires that the transfer switch safely disconnects JEA service before the generator is energized - this is a code requirement for worker safety on JEA lines after storm events.
