What is an electrical panel?
The panel is the heart of your electrical system. Power comes in from the meter, goes through the main breaker, and splits out to circuits. Each circuit has a breaker. The breaker trips when the circuit is overloaded or has a fault. That is what protects the wire — and the house.
A panel has two ratings that matter: the size, in amps, and the condition. A 100-amp panel in good shape is different from a 100-amp panel that is rusted, full, or has a known defect. We look at both.
Do I need a panel upgrade?
Your panel is full
No open breaker spaces. Double-tapped breakers. A subpanel added to a subpanel. That is a sign the service is too small for the house.
Your panel is old
Federal Pacific Stab-Lok. Zinsco. A fuse box. A panel from the 1950s to the 1980s with no main breaker. Age alone does not mean it has to go, but age plus a defect does.
Your breakers trip often
The air conditioner trips the breaker. The microwave trips the breaker. You cannot run two large appliances at once. That is a load problem, not a breaker problem. A bigger breaker on the same wire is dangerous. The fix is a larger service, or a new circuit, or both.
You are adding load
An EV charger. A pool pump. A hot tub. A home office with a server. A new air conditioner. A remodel with a new kitchen. Each one adds load. We do a load calculation first. That tells us if the panel can carry it.
Your insurer or inspector flagged it
A four-point inspection flags old panels, aluminum wiring, double-tapped breakers, and missing covers. Many insurers will not insure a house with a Federal Pacific or Zinsco panel. A panel upgrade fixes the flag.
Your panel is hot, buzzing, or rusted
Heat, buzzing, and rust are signs of a failing panel. Do not open a hot panel. Call [PHONE].
100 amp vs 200 amp vs 400 amp
100 amp
A 100-amp service was standard in many Fort Pierce homes built in the 1960s and 1970s. It can carry a small house with gas heat, gas water, and no EV charger. It cannot carry a modern all-electric house with an air conditioner, an electric dryer, an electric water heater, and an EV charger.
200 amp
A 200-amp service is the standard for a modern house. It carries an air conditioner, an electric dryer, an electric water heater, a kitchen full of appliances, and a Level 2 EV charger, in most cases. We do a load calculation to confirm it for your house.
400 amp
A 400-amp service is for a large house, a house with two air conditioners, a pool, a hot tub, and an EV charger, or a house with a large addition. It is not common in Fort Pierce, but we do it when the load calculation calls for it.
The load calculation is the key. It adds up the loads in the house — air conditioning, water heating, cooking, laundry, pool, EV, and general loads — and the service is sized to that total. The size is not guessed. It is calculated.
Federal Pacific panels
What is a Federal Pacific Stab-Lok panel?
A Federal Pacific panel with Stab-Lok breakers was installed in many houses from the 1950s to the 1980s. The breakers can fail to trip when they should. A breaker that does not trip is a fire risk. The panel has to go.
How do I know if I have one?
Open the panel door and look at the label. It will say Federal Pacific, or FPE, or Stab-Lok. The breakers have a distinctive red stripe. If you are not sure, call us. We will look and tell you.
Will my insurer refuse me?
Many insurers will. A four-point inspection will flag it. If you are buying or selling a house with a Federal Pacific panel, the insurer will ask for a replacement. The fix is replacement, not repair. There is no approved repair that makes a Stab-Lok panel safe.
What does replacement cost?
We give you a price in writing after we see the job. The price depends on the panel size, the condition of the wiring, the permit, and the meter pull. Read the full article: Federal Pacific Panel in Fort Pierce
Zinsco panels
What is a Zinsco panel?
A Zinsco panel was installed in many houses from the 1950s to the 1980s. The bus bars can fail. The breakers can melt to the bus. That is a fire risk. The panel has to go.
How do I know if I have one?
Open the panel door and look at the label. It will say Zinsco, or Sylvania Zinsco. The breakers are a distinctive shape. If you are not sure, call us. We will look and tell you.
Will my insurer refuse me?
Many insurers will. A four-point inspection will flag it. The fix is replacement, not repair.
What does replacement cost?
We give you a price in writing after we see the job. The price depends on the panel size, the condition of the wiring, the permit, and the meter pull. Read the full article: Zinsco Panel in Fort Pierce
What is a fuse box, and does it need replacing?
A fuse box uses fuses instead of breakers. Fuses work, but they are old. A fuse box cannot carry a modern load. It has no room for new circuits. Many insurers will not insure a house with a fuse box. The fix is a panel upgrade to a breaker panel.
How a panel upgrade works
Step 1: Load calculation and inspection — An independent electrician looks at the panel, the meter, the wiring, and the loads in the house. The electrician does a load calculation and tells you if you need 200 amp or 400 amp, or if a repair is enough.
Step 2: Permit — A panel upgrade needs a permit. The permitting authority is the City of Fort Pierce inside city limits, and St. Lucie County outside the city. The electrician pulls the permit. How long does a permit take? It depends on the job and the authority. Straightforward electrical permits are often plan-checked in one to two weeks, but that is a secondary source and no timeline is promised. [VERIFY]
Step 3: Meter pull — The utility has to pull the meter, or the service has to be disconnected, so the panel can be replaced safely. The electrician coordinates that. Tell us your utility when you call — Fort Pierce Utilities Authority or Florida Power and Light. Check your bill. It names your utility. Read more: FPUA vs FPL in Fort Pierce
Step 4: Replacement — The electrician removes the old panel, installs the new panel, and re-terminates the circuits. Damaged wiring is replaced where found. Every circuit is labeled. A whole-home surge protector can be installed at the same time if you want one. That is the cheapest time to do it.
Step 5: Inspection — The permitting authority inspects the work. The electrician calls for the inspection and is there when the inspector comes. If the inspector flags anything, the electrician fixes it.
Step 6: Power back on — The utility puts the meter back. The electrician tests every circuit and the panel, then cleans up and gives you the inspection report for your insurer.
How pricing works
We give you a price in writing after we see the job. The final price depends on panel condition, access, parts, and permit.
What moves the price up: a panel in bad shape, corrosion, a long run from the meter, a permit, a meter pull, and wiring that has to be replaced. What keeps it down: a clean panel, short runs, and a job we can see clearly before we quote it.

Should I repair my panel or replace it?
Repair is enough when the panel is in good shape, the brand is not a known defect, and the problem is one breaker or one loose connection. We replace the breaker, tighten the connection, and test it.
Replacement is needed when the panel is a Federal Pacific or Zinsco, when it is rusted, when it is full with no room, when it has no main breaker, or when the load calculation says the service is too small. We will tell you which one it is. We will not sell you a new panel when a repair will do.
Frequently asked questions
How long does a panel upgrade take?
One day for most 100-amp to 200-amp upgrades, once the permit is in hand and the meter pull is scheduled. A 400-amp upgrade or a job with a rewire takes longer. We tell you the time before we start.
Will my power be off all day?
Yes, for most of the day. Plan for it. Fridges and freezers will hold for a few hours if you do not open them. We will tell you the window before we start.
Do I need a surge protector with a new panel?
We recommend it. A whole-home surge protector at the panel guards the whole house. In a lightning-prone area, it guards a fridge, an air conditioner, and a television. It costs less when it is installed with the panel, because the panel is already open.
Can I add an EV charger to my current panel?
It depends on the load calculation. Many 100-amp panels cannot carry a Level 2 EV charger. Many 200-amp panels can. We do the calculation first. We do not guess.
What is a subpanel?
A subpanel is a smaller panel fed from the main panel. It adds breaker spaces where the main panel is full. It does not add service size. If the main service is too small, a subpanel does not fix it. A panel upgrade does.
Will a panel upgrade help me sell my house?
Yes, in most cases. A new panel passes a four-point inspection. An old Federal Pacific or Zinsco panel fails it. A buyer, and a buyer’s insurer, will ask for a replacement. A new panel removes that problem.
