Why Are Federal Pacific Panels So Scary?
If an electrician has ever looked at your electrical panel and said, “Oh, that's a Federal Pacific panel,” you may have wondered why they care so much.
Maybe you've heard Federal Pacific panels are dangerous. Maybe a home inspector mentioned yours. Or maybe you just noticed the name Federal Pacific or Stab-Lok inside your panel door and started searching online.
So what's actually wrong with them?
The main concern is pretty simple:
Some Federal Pacific breakers have been found to stay on when they're supposed to trip off.
And shutting the power off when there's a problem is one of the most important jobs a circuit breaker has.
Here's what that means for your home.
What Is a Federal Pacific Electrical Panel?
Federal Pacific Electric, often shortened to FPE, was a manufacturer of electrical panels and circuit breakers commonly found in older homes.
Many Federal Pacific panels use a type of circuit breaker called a Stab-Lok breaker.
If you have one, you may see names such as:
Federal Pacific Electric
Federal Pacific
FPE
Stab-Lok
You may find these markings on a label inside the panel door or on the front of the breakers where they're already visible.
The name itself isn't what creates the concern.
It's what some of these breakers have done during testing.
Why Are Federal Pacific Panels a Concern?
First, let's make “what is a circuit breakers” really simple.
A circuit breaker isn't just an ON/OFF switch.
It's there to help protect the wiring in your home.
Imagine you have several things plugged into the same circuit and that circuit starts pulling more electricity than the wiring is designed to safely handle.
The breaker is supposed to recognize that problem and:
CLICK — shut the power off.
You've probably seen a breaker do this before.
Maybe you plugged too many things into the same circuit and suddenly part of the house lost power.
That's annoying — but the breaker was actually doing its job.
Here's where the concern with Federal Pacific comes in.
Certain Federal Pacific Stab-Lok breakers have been found in testing to sometimes stay on when they should trip off.
That's the main problem.
Imagine a circuit in your home becomes overloaded.
Normally:
Too much electricity → breaker trips → power shuts off.
But if the breaker doesn't trip:
Too much electricity → breaker stays on → electricity keeps flowing.
That can allow wiring or other electrical components to continue heating up.
And that's where the fire concern comes from.
It doesn't mean every Federal Pacific breaker will fail.
It means these breakers have enough of a concerning history that electricians pay attention when they find them.
Why Can a Federal Pacific Panel Look Completely Normal?
This is where Federal Pacific panels can be confusing for homeowners.
You could look at your panel and see absolutely nothing wrong.
Your lights work.
Your outlets work.
Your air conditioner runs.
The panel isn't making noise.
Nothing smells burned.
And the breakers may have been sitting there for years without causing an obvious problem.
So why worry about it?
Because the concern isn't necessarily whether the breaker can provide electricity during normal use.
The concern is whether it will shut the electricity off when something goes wrong.
Think about a seat belt.
You don't know whether a seat belt is going to protect you just because you've driven the car every day without a problem.
You find out when you actually need it.
A circuit breaker is similar.
It can sit there quietly supplying electricity for years.
The important question is what happens when that breaker actually needs to protect the circuit.
That's also one reason we recommend looking at more than just whether an electrical panel appears to be working.

How Do I Know If I Have a Federal Pacific Panel?
You may be able to identify one yourself without taking anything apart.
Open the panel door and look at the information that's already visible.
Look for names such as:
Federal Pacific Electric
Federal Pacific
FPE
Stab-Lok
You may see the manufacturer's name on a label or see Federal Pacific or Stab-Lok markings on the breakers.
Don't remove the panel cover to look for it.
There's an important difference between opening the little panel door and removing the actual screwed-on cover around the breakers.
Opening the door to read a visible label is one thing.
Do not remove screws, take the panel cover off or reach inside the panel just to identify it.
There can be energized electrical components behind that cover.
If you can't tell what you have from the information that's safely visible, let an electrician identify it.
Does Having a Federal Pacific Panel Mean My House Is Unsafe?
Not automatically.
Finding Federal Pacific equipment doesn't mean your house is about to catch fire.
And it doesn't mean every Federal Pacific breaker is guaranteed to fail.
The concern is that this equipment has a documented history of breakers not operating properly during testing.
That's why we wouldn't recommend ignoring one simply because everything in the house currently works.
Instead of panicking, the reasonable next step is:
Find out exactly what you have and have it professionally evaluated.
Does My Federal Pacific Panel Have to Be Replaced?
Not every homeowner should be told:
“You have an old panel. Replace it.”
We'd rather look at what you actually have first.
Federal Pacific Stab-Lok equipment's history is one reason an electrician may recommend replacing the panel.
But there are other things we can look at too, including:
Overall condition of the panel
Signs of overheating
Corrosion or damage
Condition of the breakers
Available breaker space
Electrical capacity
Changes or additions made over the years
Future electrical needs
For example, a homeowner planning to add an EV charger, generator, larger HVAC system or other major electrical load may have additional reasons to evaluate the existing panel.

The important part is understanding what we're recommending and why we're recommending it.
What Should I Do If I Think I Have a Federal Pacific Panel?
Don't start taking the panel apart.
Don't start flipping breakers to “test” them.
And you don't need to panic.
Have someone who knows what they're looking at check it out.
That's the easiest first step.

Federal Pacific Panel FAQs
-
Federal Pacific Electric, often called FPE, manufactured electrical panels and circuit breakers that can still be found in older homes today. Many of these panels use Stab-Lok breakers.
-
Stab-Lok is the name of a circuit breaker design used in many Federal Pacific panels.
The concern is that certain Stab-Lok breakers have failed to trip properly during testing.
-
A breaker is supposed to shut off electricity when too much current is flowing through a circuit.
Testing has found cases where certain Federal Pacific Stab-Lok breakers did not trip when they should have.
If a breaker doesn't shut the power off, electrical wiring and components may continue heating up.
-
Look for Federal Pacific Electric, Federal Pacific, FPE or Stab-Lok markings that are already safely visible on the panel or breakers.
Do not remove the screwed-on panel cover or touch anything inside the panel to identify it.
-
No. Finding a Federal Pacific panel doesn't mean a fire is guaranteed or that your home is immediately unsafe.
It does mean you have electrical equipment with a concerning history that is worth having professionally evaluated.
-
An electrician can first identify the equipment and evaluate the panel before discussing replacement.
Because of the history surrounding certain Federal Pacific Stab-Lok breakers, replacement may be recommended. Your electrician should be able to explain what they're recommending and why.
-
Yes.
In fact, that's a good place to start if you're unsure what you have.
