Signs You Need an Electrical Panel Upgrade in St. Augustine
Most homeowners find out they need a bigger or newer panel in one of two ways. Something starts to go wrong, or a new project shows the panel can’t support it.
Watch for breakers that trip often or won’t reset. Watch for lights that flicker or dim when the AC or a major appliance starts, and for panel hardware that’s warm or buzzing, or looks discolored. No open spaces for new circuits is another sign, and so is an older panel brand with a known history of problems.
Notice any of these? Have an electrician take a look.
Projects That Call for More Capacity
Many upgrades start with something new. Each of these adds load to your panel:
- EV chargers, which pull a heavy load for hours at a time
- Standby generators and their transfer switches
- Home additions, finished garages and remodeled kitchens
- Pools, spas and workshops
Builder-grade panels in newer neighborhoods, and original panels in older homes, are often already full. We do a load check and tell you honestly whether you need an upgrade. See our pages on installing a Level 2 EV charger and generator installation pages for more.
100 to 200 Amp Service Upgrades and Panel Replacement
Many older St. Augustine homes were built with 100 amp service. That was enough when the biggest load was a window AC. Not anymore. Central air, electric appliances and EV charging now push most homes toward 200 amps.
A service upgrade replaces the panel and often the wiring that feeds it. A straight panel replacement swaps an old or damaged box for a new one with current breakers and open spaces.
Utility Coordination, Permit and Inspection
A service upgrade involves more than the panel. The utility has to disconnect and reconnect power at the meter, so we coordinate with them and plan the work around that step.
We also pull the electrical permit and schedule the inspection. In St. Johns County, the permitting office depends on where you live, and we handle the paperwork either way. The inspector signs off before the work is final.
Pair Your New Panel With Surge Protection
Northeast Florida gets frequent lightning and plenty of power flickers. Once we’ve opened your panel for an upgrade, adding whole-house surge protection is simple.
The surge protector mounts at the panel and helps block spikes before they reach your AC, appliances and electronics. For more home electrical work, see our residential electrical services.
What Happens During an Upgrade
We start with a visit to look at your current panel and calculate your home’s electrical load. You get a written quote and an honest recommendation, including the option to leave the panel alone if it’s fine.
On upgrade day, we shut off power, remove the old panel, mount the new one and connect each circuit. We label every breaker, test the system and restore power. The inspector then verifies the work.
Most of the effort happens before any wire is touched. We plan the service size, schedule the utility and secure the permit.
Older Homes and Newer Neighborhoods
Panels in St. Augustine’s older homes and in Nocatee’s newer ones fail the load test for different reasons. A house from the 1960s may have a small panel with no room left. A home built in the 2000s may have a builder-grade panel already filled by the original circuits.
Either way, a panel upgrade now is easier than a rushed one later. Thinking about an EV charger, a generator or an addition? Ask for a load check before you buy the equipment. We serve all of St. Johns County, including St. Augustine and Nocatee.
