This article explains the possible hazards of the Federal Pioneer Stab-Lok electrical panels & circuit breakers,in more recently manufactured FP product versions.

The Federal Pioneer brand of electrical panels and circuit breakers is a Canadian version of the Federal Pacific Electric Stab-Lok equipment. The FPE website explains the hazards associated with the American product: Federal Pacific Electric Stab-lok circuit breakers and service panels, provides a history of the issue, recounts research on FPE failures, and recommends replacement of the panels.

Readers should also see HOW TO IDENTIFY FPE & FP for help in identifying Federal Pioneer old and more recently-manufactured Stab-lok products, and see FEDERAL PIONEER in CANADA for a discussion of the safety of older Federal Pioneer equipment. These discussions pertain only to the Federal Pioneer Stab-Lok electrical equipment brand made in Canada, not to the Federal Pacific Stab-lok brand made and installed in the United States.

Are Newer Federal Pioneer Stab-Lok Electrical Panels Safe ?

In Canada, the Federal Pacific Electric FPE Stab-lok electrical panel and circuit breaker line was sold under the brand name Federal Pioneer or FP or FP Stab-Lok.

We have much less field and test data on the Canadian FP products. There was a 1997 Canadian FP recall notice (discussed at Federal Pioneer Electrical Circuit Breaker Recall) and a 1997 warranty alert (discussed at Federal Pioneer Warranty Alert).

We have received only a few field reports about Canadian FP installations than U.S. FPE installations, but we lack data to know if that’s due to fewer website readers from Canada, fewer FP panels installed in Canada than FPE in the U.S., better Canadian electrical wiring workmanship overall, fewer electrical events that should trip the breaker, or a better product or redesigned product in the Federal Pioneer versions of this equipment sold in Canada.

In sum:  as of April 2008 we cannot report that the Federal Pioneer panels perform the same, better, or worse than the older, discontinued US Federal Pacific Electric or FPE Stab-Lok version of this product.  

Building owners should not rely on any Federal Pacific Electric Stab-lok electrical panels, and building owners should be cautious about continuing to rely on any older Canadian Federal Pioneer design.

But it is certainly possible that Canadian versions - the Federal Pioneer equipment made much more recently, say after 1997, may have been improved-on and might perform acceptably.

We’d like to see photos of recent Canadian FP electrical panels, labels, and interior bus design and breakers to perhaps be able to offer more information.

History of Federal Pioneer Electrical Panels & Breakers made in Canada

Schneider Electric in Canada purchased and has continued to market the Federal Pioneer line (which is the Canadian version of Federal Pacific Electric) of Stab-Lok products.

Quite some time ago we (D Friedman) asked a Schneider engineer if Schneider made any product changes or improvements over the original FPE Stab-Lok version when it was picked up in Canada. While at first he was friendly, later, perhaps after talking with management, neither the engineer I spoke with nor anyone else at Schneider responded to any questions about this product whatsoever.

(The photo shows old and new circuit breakers such as seen in the Federal Pioneer NBLP38-TF32 electrical panel photographed in 1997)

At that time, I took that to mean that perhaps the company had no compelling good news to report, but I acknowledge that they could simply be afraid to share test or any other data, regardless of the product’s performance, as I explain below.

Some of the original product problems appear to have been inherent in the design of the breaker internal parts and the bus assembly, and I was told by some engineers that a redesign to correct these problems would have priced the product out of its niche in the market (the low end).

So we are faced with the situation of a company who has so far not provided public information about the product’s testing, performance, or engineering changes. We would very much welcome a Federal Pioneer product testing and performance update so to be able to inform to consumers whether or not later versions of the Federal Pioneer product line have been improved and perform acceptably.

I speculate that Schneider/Federal Pioneer may have indeed made corrections or improvements in the product since the 1970’s and 80’s, and I speculate further that they may be reluctant so say so since that would admit prior problems and thus risk liability and claims.

What should a Homeowner Do About a Recently-Made Federal Pioneer Electrical Panel?

I would not assume that the newer Canadian Federal Pioneer electrical panels and circuit breakers are unacceptable or unsafe,  but given the very bad performance of the original designs of the original FPE Stab-Lok product which were widely sold over many years, I would not fail to look for more current test and engineering data on this product.

(The photo shows the data label in a Federal Pioneer electrical panel model NBLP32B-4NBCFB taken in 1997)

Comments & Questions for Schneider about FP Panels

If it were my home and my panel shown at the top of this page, I would call the Schneider Electric company and, in as respectful a manner as I could, I’d simply put these questions to them

1. The older versions of the product clearly had problems in the U.S. and at least some failures in Canada, (there was a Canadian product alert notice)
   
   
2. Schneider Electric Co. has continued to produce and sell the Federal Pioneer brand electrical panel
   
   
3. Newer Federal Pioneer electrical panels and breakers, though they may still be a Stab-lok design, look a little different than the older ones by simple visual inspection of the electrical panel and circuit breaker colors and toggle switch handles.
   
   
4. Can or will Schneider Electric provide any test reports or technical data about any changes or improvements in the product since the era when Schneider picked it up?

Federal Pioneer Electrical Panel Field Reports Requested

We invite building owners, electricians, fire marshals, manufacturers, or independent testing laboratories to report to us on the field performance or field failures or product testing results for this product and we will publish here any updates we are able obtain.

We’d also like to see photos of the bus design itself – an electrician can open the panel – remove the cover, and if necessary pull a breaker to expose the bus and breaker connectors – that might tell us if visible changes were made even if we don’t know if internal breaker design changes were made.
