# Federal Pacific Panels and Aluminum Wiring: What Homeowners Need to Know

Federal Pacific (FPE) Stab-Lok panels and aluminum branch wiring are two older-home concerns. The CPSC says FPE breakers failed some UL tests but closed its 1983 probe without proving a hazard. It links aluminum wiring to overheating at connections. Identify them by label, never by opening the panel. Call a licensed electrician.

## Two different problems

A Federal Pacific panel is a brand of breaker box. Aluminum wiring is a type of wire inside the walls.

## Look, do not open

Read labels on the panel door and on visible cable. The CPSC says not to open the panel interior, which can expose live wires.

## What the CPSC found

FPE breakers failed certain UL calibration tests, and the CPSC closed its probe in 1983 without a hazard finding.

## Get an electrician's view

A licensed electrician can confirm what you have and explain repair or replacement choices for your home.

## What are a Federal Pacific panel and aluminum wiring?

A Federal Pacific panel is a breaker box made by Federal Pacific Electric (FPE), often with Stab-Lok breakers. Aluminum wiring is a type of branch wire used in some homes decades ago. They are different problems, but both show up in older homes.

Our pillar page on [electrical panels and service upgrades](https://danielelectric.multisites.ai/guides/electrical-panels-and-service-upgrades) covers the wider topic.

## Is a Federal Pacific panel dangerous?

The record is mixed, so we report it plainly. The CPSC says testing confirmed that FPE breakers fail certain UL calibration test requirements. Yet it also closed its investigation in 1983 because the data did not establish a serious risk of injury.

Here is what the CPSC release says. The agency began looking at FPE breakers in June 1980, when the parent company reported that many did not fully comply with UL requirements. A breaker must hold its rated current and also trip within set time limits when a circuit is overloaded. Testing confirmed the failures of certain calibration tests. The CPSC then said it was unable to link those failures to a hazardous situation. It stated that its staff had insufficient data to accept or refute the manufacturer’s position. It decided not to commit more resources and added that it could reopen the investigation.

The CPSC release carries a note added when it was revised. The note says staff advises electricians, homeowners, home inspectors and real estate agents to read the release carefully. It says the agency closed the matter without determining that the breakers are safe or that the manufacturer’s position is accurate.

So what do homeowners do with this? Treat it as an open question and get an expert look. Daniel Electric’s own site says that if you have a Federal Pacific breaker panel, it will remove it to prevent electrical fires. You can ask for an inspection and a written opinion before you decide.

A tripped breaker matters in any panel. The CPSC advises people to find out why a breaker trips, and not to simply reset it. Our post on a breaker that keeps tripping explains the safe steps.

## How do I tell if I have a Federal Pacific panel?

Read the label on the panel door or the front. Look for the names Federal Pacific Electric, FPE or Stab-Lok. That is all you should do yourself. Do not remove the inner cover, because that exposes live parts.

1.  Read the label on the outside of the panel, or on the inside of the door if it has one. Do not remove any cover.
2.  Look for a brand name, a model label or a list of breaker numbers.
3.  Take a clear photo of the label.
4.  Do not touch any breaker or wire inside.
5.  Send the photo to a licensed electrician or bring it to a quote visit.

If you smell burning, hear buzzing, or see scorch marks or a hot cover, leave the area and call 911. Read our guide to [electrical warning signs](https://danielelectric.multisites.ai/guides/electrical-warning-signs).

## Is aluminum wiring safe?

It needs attention. The CPSC says the fire hazard is at the connections, where aluminum wiring can overheat. The agency estimates that 2 million homes were built with aluminum wire between 1965 and 1973.

The CPSC release lists warning signs that can point to a hazard in aluminum-wired circuits: faceplates on outlets or switches that are warm to the touch, flickering lights, circuits that do not work, or the smell of burning plastic. It adds that a failure can lead to arcing and a serious fire that can spread inside walls before anyone sees it.

So aluminum wiring is a reason to act, not a reason to panic. Keep these points in mind:

1.  Check the cable markings, not the color of the outlet or switch.
2.  Warm or discolored outlets deserve a look no matter the wire type.
3.  Do not open boxes or panels to look. Ask an electrician or home inspector.

Our post on [aluminum wiring in older DFW homes](https://danielelectric.multisites.ai/blog/aluminum-wiring-older-dfw-homes) gives local background.

## How can I tell if my home has aluminum wiring?

Look at the cable where you can see it safely. The CPSC says aluminum wiring is marked with Al or Aluminum every few feet along the cable. You may see it in an unfinished basement, an attic or a garage.

The CPSC also says a home inspector or qualified electrician can help identify aluminum wiring. It advises people not to open the interior of the panelboard or circuit breaker compartment, because that can expose live wires and pose an electrocution hazard.

Where you look

What to look for

What not to do

Exposed cable in an attic or garage

“Al” or “Aluminum” printed on the cable jacket

Do not cut, move or open anything

Unfinished basement

Same markings on cable runs

Do not open a junction box

The panel door

A brand label

Do not remove the inner cover

Outlets and switches

Warm faceplates, flicker, burning smell

Do not keep using a warm outlet

## How is aluminum wiring repaired?

Repair means making the connections safe or replacing the aluminum circuits with copper. The CPSC release says twist-on connectors and devices that connect directly to aluminum wire are an inadequate solution. A licensed electrician should do any repair.

The same 2003 release names the COPALUM crimp connector as the repair system that CPSC recognized as a complete and permanent fix at that time. It adds that the repair materials and tools were only available to trained electricians. Product availability changes over time. Ask a licensed electrician which repair methods are available today and which they recommend.

A repair plan should include:

1.  An inspection of the aluminum circuits and the connections at outlets, switches and the panel.
2.  A written scope that says which method is used and where.
3.  A permit where your city requires one.
4.  An inspection after the work.

Another route is replacing aluminum circuits with copper wiring. That is a larger job and may open walls. Your electrician can tell you where each route makes sense.

## What about insurance, sales and inspections?

Buyers’ inspectors and insurers sometimes ask about both items. We keep this section factual. Ask your insurer what it needs, and ask a licensed electrician for a written assessment.

If you are buying or selling, our post on [electrical checks when buying or selling a house](https://danielelectric.multisites.ai/blog/electrical-checks-buying-selling-house) lists the questions to ask.

If you are

Do this

Buying

Ask for the panel brand and the wire type in the inspection report, then ask a licensed electrician about anything flagged

Selling

Get a written assessment from a licensed electrician before listing, so you know what a buyer may raise

Staying

Schedule an inspection if you see warning signs or want a clear plan

Local code and permit rules apply to panel and wiring work. TDLR says anyone who performs non-exempt electrical work in Texas must be licensed and work through a licensed electrical contractor. See our guide to hiring a licensed electrician in Texas. Read what to expect from a panel job in our guide to electrical panel replacement.

## What should I ask an electrician about an FPE panel or aluminum wiring?

1.  Can you identify the panel brand and the wire type, and show me where you found them?
2.  What do you advise for my home, and why?
3.  If you recommend repair or replacement, what exactly will you do and in what order?
4.  Is a permit needed, and who applies?
5.  What does your warranty cover? Daniel Electric lists its terms on the warranty page.

## What if I decide to wait?

If you wait, do it with your eyes open. Get the inspection first, then decide. Do not wait if you see a warning sign.

While you wait, follow these rules:

1.  Do not add big new loads to the panel or the old circuits, such as a hot tub, an EV charger or a large appliance, until an electrician has looked.
2.  Do not use a warm or discolored outlet.
3.  Do not keep resetting a breaker that trips.
4.  Know where your main breaker is, and make sure everyone in the home does too.
5.  Test your smoke alarms. See our guide to smoke and CO alarms for the basics.
6.  Write down any sign you notice and the date, and share the notes with your electrician.

Waiting is a choice that should rest on an electrician’s written opinion, not on a guess.

## Frequently asked questions

### Is a Federal Pacific panel dangerous?

The record is mixed. The CPSC says testing confirmed FPE breakers fail certain UL calibration tests, but it closed its 1983 probe because the data did not establish a serious risk. It said it could not accept or refute the maker's position. Daniel Electric says it removes Federal Pacific panels. Ask a licensed electrician to inspect yours.

### How do I know if I have a Federal Pacific panel?

Read the label on the panel door or cover. It may name Federal Pacific Electric or Stab-Lok. Do not remove the inner cover to look, because that exposes live parts. If you cannot read the label or are unsure, a licensed electrician can identify the panel safely.

### Is aluminum wiring safe?

Aluminum branch wiring is a known fire concern at its connections, according to the CPSC. The agency says failing connections can overheat. A home with aluminum wiring is not always on fire, but the connections need attention. Have a licensed electrician inspect them and explain repair options.

### How can I tell if my home has aluminum wiring?

The CPSC says aluminum cable is marked with Al or Aluminum every few feet, and you may see it in unfinished basements, attics or garages. Homes built between 1965 and 1973 are the main concern. Do not open panels or boxes. A home inspector or electrician can confirm.

### Can I fix aluminum wiring with twist-on connectors?

The CPSC says twist-on connectors and devices that connect directly to aluminum wires are an inadequate solution. Repairs should follow approved methods and be done by a licensed electrician. Do not try to repair aluminum wiring yourself or add unapproved parts.

### Should I replace a Federal Pacific panel before I sell my house?

Talk to a licensed electrician and your real estate agent. A buyer's inspector may flag an FPE panel, and insurers sometimes ask about it. A replacement before listing is a choice, not a rule. An electrician can inspect the panel and give you a written assessment to share.
