Step-by-Step Panel Upgrade Process in Naples | CoHarbor Electric

One of the most common things we hear after finishing a panel upgrade is some version of: “That was way less of a deal than I thought it was going to be.” People build it up in their heads as this massive, multi-day ordeal where the house is torn apart and the power’s off for days. The reality is usually a single day of work, a few hours without power, and a home that’s significantly better off electrically than it was that morning.

But the process does have steps, and in Collier County the process has some specific moving parts that are worth understanding before you start. Knowing what to expect — what happens in what order, who’s involved, what you need to do — makes the whole thing a lot smoother.

So here’s how it actually goes when Coharbor Electric does a panel upgrade in Naples.

First: Figure Out What You Actually Need

Before anything else, someone needs to look at what you’ve got and what you’re trying to accomplish. That’s usually us coming out for a site visit. We look at the existing panel — its age, its condition, its amperage, how many spaces are used versus available — and we talk through what’s driving the project.

Sometimes the driver is obvious. The panel is a 100-amp unit from the 1980s and it’s failing. Or there’s a pool going in and there’s nowhere to put the circuits. Or someone’s adding an EV charger and the load calculation doesn’t work. Sometimes it’s less obvious — the homeowner just knows something feels off, breakers are tripping more than they used to, the panel feels warm.

Whatever brought it to a head, the site visit is where we figure out whether a panel replacement is the right move, what service size makes sense (100 amps, 150, 200 — for most Naples homes today, 200 is the standard recommendation), and whether there’s anything else we need to address at the same time, like the service entrance conductors or the meter base.

We also do a load calculation. That’s not optional — it’s required by code and it’s what tells us whether a 200-amp service is adequate for the home’s existing and planned loads. NEC Article 220 covers the methodology. For most single-family homes in Naples, 200 amps handles it. For larger homes in areas like Port Royal or Pelican Bay with significant square footage, multiple AC systems, and all the amenities that come with those properties, we look at the numbers before assuming.

Pulling the Permit

This is the step some contractors try to skip. We don’t.

A panel replacement in Collier County requires a permit from Collier County Growth Management. No exceptions for size, no “it’s just a panel swap” exemption. If someone tells you they can do a service upgrade without pulling a permit, they’re telling you the work won’t be inspected — and that creates real problems down the road when you sell the house or make an insurance claim.

The permit application for a panel upgrade includes a description of the work, the existing and proposed service sizes, and in some cases a simple single-line diagram showing the service entrance configuration. We handle all of this. Most homeowners never deal directly with the permit office at all.

Permit turnaround time in Collier County can vary — it’s generally a few business days for a straightforward residential panel replacement, sometimes a bit longer depending on the workload at the county. We factor this into scheduling so we’re not waiting on paperwork at the last minute.

Coordinating with LCEC

This is the piece of the process that surprises a lot of Naples homeowners: we can’t just shut off your power ourselves and start the work. The utility — LCEC (Lee County Electric Cooperative) serves most of Naples and the surrounding Collier County area — owns the meter and the service entrance up to the meter base. Before we can work on the service entrance, LCEC needs to pull the meter.

We contact LCEC to schedule the temporary disconnection. They pull the meter, which de-energizes the service entrance conductors so we can work safely. When the panel work is done, we call them back to reinstall the meter and restore power.

LCEC is generally pretty cooperative about scheduling this, but they’re working on their own timeline. We typically schedule LCEC and the customer at the same time so everything lines up. For a morning panel upgrade, LCEC usually pulls the meter early, we do the work through the day, and power is back on by mid-afternoon or evening in most cases.

One thing worth knowing: if your meter base is damaged or undersized for a 200-amp service — which is sometimes the case on older homes — LCEC may require an upgrade to the meter base before they’ll reconnect. We identify this during the site visit so it’s not a surprise on the day of work.

The Day of the Upgrade

Morning: LCEC Pulls the Meter

The day starts with LCEC arriving to pull the meter. Once that’s done, the service entrance is de-energized and we can start working safely. From the homeowner’s perspective, this is when the power goes off.

Most people in Naples are used to occasional outages from storms, so a planned power-off day is manageable. We give customers a heads-up: charge your devices the night before, if you have a well pump plan around it, keep the refrigerator and freezer closed as much as you can. For a full day of work, there’s some inconvenience, but nothing that requires leaving the house.

Removing the Old Panel

We start by documenting the existing panel — photographing the wiring before we touch anything, noting which breakers serve which circuits. This matters because when the new panel goes in, we want everything reconnected correctly and labeled clearly. A common complaint people have about their existing panels is that the directory is either blank, wrong, or says something helpful like “bedroom” with no further detail. We fix that in the process.

The old panel comes off the wall. On older homes in Naples — particularly the ones in established neighborhoods like Naples Park, Golden Gate, and the older sections of East Naples — we sometimes find surprises inside the wall once the panel is removed. Old wiring methods, previous splices that shouldn’t be there, moisture damage to the wall cavity. We deal with whatever we find.

Installing the New Panel

The new panel goes in. For most residential Naples upgrades, we’re installing a 200-amp main breaker panel with 40 or more circuit spaces. The service entrance conductors — the large conductors coming from the meter base into the top of the panel — get connected to the main breaker lugs. All the branch circuit wiring gets redistributed and landed on the new breakers.

We also address the grounding and bonding at this stage. The panel needs to be properly bonded to the grounding electrode system — typically ground rods and sometimes a concrete-encased electrode (the Ufer ground) in a slab-on-grade home, which describes the vast majority of Naples construction. If the grounding system is inadequate or outdated, we correct it.

One thing we see regularly in Naples homes that sat through hurricane seasons: the service entrance conductors get physically stressed over time from wind movement. We inspect those conductors and the service entrance components while everything is open. If anything needs to be replaced, now is the time to do it.

Labeling and Testing

Before we call LCEC to restore power, every circuit in the new panel gets labeled. Not just “kitchen” — we take the time to identify what’s actually on each circuit. It takes an extra half hour and homeowners consistently appreciate it later.

We also do a visual check of the entire installation — connections are tight, breakers are properly seated, the grounding is right, the panel cover fits correctly. Any issues get corrected before the meter goes back in.

The Inspection

After the panel is installed and LCEC has restored power, we schedule the inspection with Collier County. An inspector comes out, looks at the installation, verifies it meets code, and signs off on the permit.

For a straightforward panel replacement, inspection is typically quick. The inspector is looking at the service entrance, the panel installation, the grounding and bonding, the work quality, and the permit documentation. If everything’s right, they sign off and the permit closes.

If something needs to be corrected — which is rare when the work is done properly — we address it and schedule a re-inspection. We’ve done enough of these in Collier County to know what the inspectors are looking at and to make sure it’s right the first time.

The permit being closed and inspected matters. It’s the paper trail that shows the work was done legally and to code. Insurance companies care about this. Future buyers’ inspectors care about this. It’s not bureaucratic overhead — it’s documentation that protects you.

What the House Looks Like After

The physical footprint of the work is pretty minimal. The panel is in the same location, or occasionally relocated if there was a reason to move it. The service entrance looks the same from the outside. Inside the panel, everything is clean, properly organized, and labeled.

What changes is what the panel can do. For a home that was on 100-amp service, there’s now headroom to add circuits, support larger loads, and handle whatever comes next without worrying about capacity. For a home that had an old, corroded panel, there’s now equipment that’s actually designed to protect the wiring and the house.

We walk through the new panel with the homeowner before we leave — show them where the main breaker is, explain the circuit directory, go over anything we found during the work that they should know about. If there’s follow-on work we’d recommend (older wiring in a specific area, an outlet that needs a ground, something we noticed while we had everything open), we tell them about it then.

How Long Does It Actually Take?

For a straightforward residential panel replacement in Naples — existing service entrance is intact, no major surprises, 200-amp upgrade from 100-amp service — the electrical work is typically a full day. Permit processing happens before the work day. LCEC coordination happens the same day as the install.

More complex jobs take longer. If we’re also replacing the service entrance conductors, upgrading the meter base, doing a service entrance relocation, or dealing with issues we find in the wall or the existing wiring, add time accordingly. We give homeowners a realistic timeline before the work starts, not an optimistic one that turns into a two-day job without warning.
