FPE Stab-Lok Breakers and Panels – Position Statement

FPE Stab-Lok Breakers and Panels – Position Statement

This brief report is in response to questions we are frequently asked regarding Federal Pacific breakers and panels.  Two of the most frequent questions we are asked:

  • Has there been any recall notices on FPE Stab-Lok circuit breakers or panels.
  • What is our opinion as to the safety of FPE Stab-Lok circuit breakers and panels.

FPE Stab-Lok Product Recall

In answer to the first question, in our research, we have not been able to verify any official product recall on the Federal Pacific Stab-Lok circuit breakers or panels.  However, on March 3rd 1983 the U.S. Consumer Product Safety Commission (CPSC) released a report basically stating that commission testing confirmed that certain FPE Stab-Lok circuit breakers failed UL calibration test requirements.  However their limited testing was insufficient for the commission to accept or refute whether the breaker failures lead to a hazardous situation.  We have attached the complete CPSC report for your review.

Our Opinion

To the second point regarding our opinion of the breakers in question, we believe that based on our personal experience, and the vast amount of second hand anecdotal information, these circuit breakers are less reliable than other comparable products produced by other manufactures, and may pose more of a failure and safety risk over other comparable products.

The primary problems associate with these breakers is that they may not trip in an overload situation, and that the breaker may not make proper contact with the panel buss.

While it is not quite correct to call a non-tripping breaker a “fire hazard”, the FPE Stab-Lok breakers (as others) are primary safety devices whose function is to stop certain electrical sequences that could, if allowed to proceed, lead to fire in a building.  By their own (FPE) admission, the breakers in question do not fully comply with UL requirements, and there is some evidence that FPE falsified testing procedures and results.  It is important to note that UL itself did not actually perform the compliance testing on the breakers, but only monitored the production and testing done at the FPE factories.  As UL standards and listings are intended to provide evidence that the product is “suitable for the purpose” under the provisions of the National Electrical Code (NEC) this is troubling to us.

Please see the table on the following page which illustrates the frequency of failures of the subject breakers.



FPE Stab-Lok Circuit Breaker Testing


Breakers Tested

Trip Failures @ 135% of Rated Current Safety Failures @ 200% of Rated Current
CPSC – Single Pole 14 4 (28%) 1 (7%)
CPSC – Double Pole 27 20 (74%) 5 (19%)
Wright-Malta Corp. – Double Pole 122 62 (51%) 12 (10%)
Independent (J. Aronstein) – Single Pole 345 61 (18%) 4 (1%)
Independent (J. Aronstein) – Single Pole GFI 5 3 (60%) 4 (80%)
Independent (J. Aronstein) – Double Pole 120 42 (35%) 14 (12%)

Another issue to consider is the fact that many FPE Stab-Lok panels are “split bus” type panels.  These are panels which do not have a main circuit breaker.  Eliminating a main circuit breaker also eliminates a safety factor in the event a branch circuit breaker jams with the contacts closed on an electrical fault.   A main breaker would provide a measure of protection at a higher current trip point.  A main breaker also provides a measure of protection when servicing or adding down stream branch breakers in an active (“hot”) panel.

The final points we would like to make is that without extensive and costly testing (not practical for individual cases), we can not confirm with a visual (“looks alright”) and mechanical inspection (“clicks on and off okay”) whether certain breakers are, or are not, defective internally.

And finally, because production of these products ceased in the mid 1980’s, the age of many of these products is now exceeding 20 years of operation (they are getting tired) and availability of replacement parts will become increasingly difficult and costly, and possess no product warranty.

Summary and Solution

Based on our research, personal knowledge, and the associated failure rates found, and because there is no safe or practical way to verify correct product operation, we believe it prudent to replace all FPE Stab-Lok panels currently in use when practical.  While we do not necessarily believe this an “emergency” situation, panelreplacement should be considered if any repair or modifications are made or required.

In conclusion, we believe that keeping these panels in operation for the long term could constitute an increased risk over other products on the market, and it may be well worth the $1000 -$1500 * average cost for replacement.

If you have any questions, or need further clarification on this issue, please feel free to contact us at any time.

Does Your Circuit Breaker Trip?

What does it mean when your circuit breaker goes off (trips)?

It’s not fun having electrical problems,  but before you call an electrician, there may be some steps you can take to fix the problem and save you the unnecessary cost of an electrical repair.

When your breaker continuously is switching to the off or middle position (or tripping) while you are using electricity or even if you are not using any electrical current, it can be one of several things:

One, you may have too many electrical appliances plugged into the electric outlet which can cause overheating or a large power surge.   Your breaker is designed as an electrical safety feature to stop power from going to the overheating wall outlet.  This means that this safety feature will automatically shut off when you have too much power going to one specific breaker and it will shut your panel breaker off to that circuit.  You will have to manually reset the breaker to get power.   To reset the breaker, push your breaker to the off position first and then back to the on position.  If you are overloading circuits you want to consider having extra receptacles or GFCI protected receptacles added by a certified electrician.

Second, it could also be a loose wire which only a certified electrician should help you repair..  You should never attempt to do wiring on your own because it would cause injury to you.

Resetting the breaker is ok to do on an occasional basis.  For example if you have plugged too much into one circuit and over loaded the circuit.  However, if you find you are resetting your breaker several times.  You might want to give us a call to take a look. Resetting the breaker too often can cause the breaker to fail and not do its job of protecting you and your home from electrical hazards.

Preventing Electrical Fires; When Should You Call an Electrician…

Safety Tips for the Prevention of  Electrical Fires

♦Work on Home electrical distribution or lighting equipment should only be conducted by a qualified electrician.  When you are buying, selling or remodeling a home, have it inspected by a professional electrician.

Call a qualified electrician or your landlord if you have:

♦recurring problems with blowing fuses or tripping circuit breakers,

♦a tingling feeling when you touch an electrical appliance,

♦discolored or warm outlets,

♦a burning smell or rubbery odor coming from an appliance,

♦flickering lights,

♦sparks from an outlet.

Arc Fault Breaker, Shuts off electricity when a dangerous situation occurs.

♦Arc fault circuit interrupters (AFCIs) are a type of circuit breaker that shuts off electricity when a dangerous condition occurs.  Consider having them installed in your home.

Say Goodbye to the Light Bulb as you Know it…

Soon you will no longer be able to purchase the traditional light bulb.  In 2007 President Bush signed a law requiring lights to meet certain efficiency standards. Starting in 2012 you will no longer be able to purchase 100 watt bulbs, in 2013, 75 watt bulbs and in 2014, 40 and 60 watt bulbs.

There are many CFL bulb options available.  Home Depot has a page on their website with good information about bulb options, applications, light output and power consumption.  The Energy Trust of Oregon can help you learn more about how to choose CFL’s, shopping tips and information on where to recycle them.   You can also check the U.S. Department of Energy’s Website.

Compact Fluorescent Light Bulb

If every American replaced just one incandescent light bulb with a CFL bulb (compact fluorescent), we would prevent nine billion pounds of greenhouse gas emissions, equivalent to keeping two-thirds of Portland metro-area cars off the road for a year”

Lighting Incentives Available for Businesses

Starting July 14th 2012 the United States Department of Energy requires new efficiency standards for the manufacture of linear fluorescent lights.  Magnetic ballasts most commonly used in T12 fluorescent fixtures will no longer be produced.  Simply put, electrical suppliers will no longer be able to purchase replacement lamps or ballasts for your T-12 fixtures.

The simplest retrofit for T-12 lamps and magnetic ballasts is a T8 or T5 lamp and electronic ballast.  This new technology produces higher quality light and less heat resulting in lower air conditioning needs and can save 30 to 40 percent on energy costs.  Portland General Electric and The Energy Trust of Oregon have more information and incentive offers to help you with this change.

Smoke Alarms Save Lives


Hard Wired Interconnected Smoke Alarms Provide the Best Protection:

The winter months bring an increase in home fires with more indoor activity and an increase in lighting, heating and appliance use.   Your best defense against these tragedies is a working smoke alarm.  Smoke alarms should be connected to your home’s wiring system, so you can be sure they are always working.  In the event of a power outage they are equipped with a battery for back-up.  It is also a good idea for smoke alarms to be inter-connected so when one goes off, they all go off.  RF (Radio Frequency), wireless, units are capable of this and are now available and do not require interconnecting wiring.  They require one detector to be hardwired and the rest work off of radio frequency and will all sound together no matter which ones senses smoke.  Interconnected smoke alarms increase your chances of escaping a house fire before it spreads out of control.  If you are unable to install smoke alarms using your house wiring, you should at the least install the battery operated type and install more than one.  No matter what type of smoke detector you choose, be sure to test it monthly and replace the battery at least yearly.  The smoke detectors themselves should be replaced every 8-10 years.   For more information contact us at 503-657-4958 or by email at info@parkinelectric.com.  Parkin Electric provides free estimates and free home safety inspections.
