What is a Zinsco panel?
A Zinsco panel is an electrical panel made by Zinsco, also sold as Sylvania Zinsco. It was installed in many houses from the 1950s to the 1980s. A lot of Fort Pierce homes from the 1970s and 1980s have one.
The problem is the bus bar. The bus bar is the metal bar that carries power to the breakers. In a Zinsco panel, the bus bar can fail. The breakers can melt to the bus. A breaker that is melted to the bus cannot trip. A breaker that cannot trip is a fire risk.
That is not a guess. It is a known defect. 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, with a coloured handle. The panel is often grey, with a label inside the door.
If you are not sure, call us. The electrician will look and tell you. Do not open the panel yourself.
Is a Zinsco panel dangerous?
Yes. The bus bars can fail. The breakers can melt to the bus. That is a fire risk. The panel can also have loose connections, corrosion, and double-tapped breakers. Age makes it worse. Salt air on Hutchinson Island and South Beach makes it worse faster.
A Zinsco panel that has worked for years can fail without warning. It does not give you a warning. It just stops tripping. That is why insurers and inspectors flag it.
Do not wait for it to fail. Call a licensed electrician.
Will my insurer refuse me?
Many insurers will. A four-point inspection will flag a Zinsco panel. If you are buying a house, the insurer will ask for a replacement before they bind cover. If you are selling a house, the buyer, and the buyer’s insurer, will ask for a replacement. If you already live in the house, your insurer may ask for a replacement at renewal.
The fix is replacement. There is no approved repair that makes a Zinsco panel safe. Do not let anyone tell you they can fix it by replacing one breaker. That does not fix the bus bar.
What is a four-point inspection?
A four-point inspection looks at four systems in a house: roof, electrical, plumbing, and heating and air. Insurers ask for it on older homes.
On the electrical side, the inspector flags old panels, aluminum wiring, double-tapped breakers, and missing covers. A Zinsco panel is a flag. We fix the flagged items, get the permit if one is needed, and pass inspection. Then you can send the report to your insurer.
What does replacement cost?
We give you a price in writing after we see the job.
What is in the price: the new panel, new breakers, the permit, the meter pull, and the inspection. What moves it up: a panel in bad shape, corrosion, a long run from the meter, wiring that has to be replaced, and a 200-amp upgrade at the same time. Many Zinsco panels are 100 amp. Many houses need a 200-amp upgrade when the panel is replaced. We give you a price in writing after we see the job.

How does replacement work?
Step 1: Inspection and load calculation
They look at the panel, the meter, the wiring, and the loads in the house. They do a load calculation. They tell you if you need 200 amp or 400 amp.
Step 2: Permit
A panel replacement needs a permit. The permitting authority is the City of Fort Pierce inside city limits, and St. Lucie County outside the city. We pull 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 we do not promise a timeline. [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. We coordinate 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
They remove the old panel, install the new panel, and re-terminate the circuits. They replace damaged wiring where they find it. They label every circuit. They install a whole-home surge protector at the same time if you want one. That is the cheapest time to do it.
Step 5: Inspection and power back on
The permitting authority inspects the work. They call for the inspection. The utility puts the meter back. They test every circuit. They clean up. They give you the inspection report for your insurer.
How long does it take?
One day for most replacements, once the permit is in hand and the meter pull is scheduled. Power will be off 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.
Should I replace it now, or wait?
Replace it now if you have one. Do not wait for a sale, a renewal, or a failure. A panel that fails to trip is a fire risk. A panel that fails a four-point inspection will cost you a sale or a policy. A new panel passes inspection, and it gives you room for an EV charger, a new air conditioner, and a modern load.
Zinsco vs Federal Pacific — what is the difference?
Both are known defects from the same era, and both need replacement. The defect is different. A Federal Pacific Stab-Lok breaker can fail to trip. A Zinsco breaker can melt to a failing bus bar. The result is the same: a breaker that cannot trip, and a fire risk. The fix is the same: replacement, not repair.
If you have either one, call us. The electrician will look and tell you which one it is, and give you a price in writing after they see the job.

Frequently asked questions
Can a Zinsco panel be repaired?
No. There is no approved repair that makes a Zinsco panel safe. Replacement is the fix.
Can I replace just the breakers?
No. The problem is the bus bar and the breaker design, not one breaker. Replacing one breaker does not fix it.
How do I know if my panel is Zinsco?
Open the panel door and look at the label. It will say Zinsco, or Sylvania Zinsco. If you are not sure, call us. The electrician will look and tell you.
Will a new panel help me sell my house?
Yes, in most cases. A new panel passes a four-point inspection. A Zinsco panel fails it. A buyer, and a buyer’s insurer, will ask for a replacement. A new panel removes that problem.
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. It costs less when it is installed with the panel, because the panel is already open.
What if my panel is not Zinsco, but it is old?
Call us. The electrician will look at it. Age alone does not mean it has to go, but age plus rust, heat, or a known defect does. They will tell you straight.
