Title: A Technical Overview of the Dangers of FPE Breakers and Panels

Introduction:

Federal Pacific Electric (FPE) breakers and panels were widely used in residential and commercial buildings from the 1950s to the 1980s. However, several studies have since uncovered various dangers associated with FPE breakers and panels, raising concerns over their safety. As a home inspector, it’s crucial to understand the risks involved with these obsolete electrical components. In this article, we will delve into the technical aspects of FPE breakers and panels and explore the reasons behind their problematic reputation.

The History of FPE Breakers and Panels:

Federal Pacific Electric Company was one of the largest manufacturers of circuit breakers and load centers in the United States during its time. FPE’s Stab-Lok breakers were popular due to their compact size and affordability, making them a go-to choice for many electricians and builders. Unfortunately, numerous cases of failures and defects began to emerge, causing FPE breakers and panels to lose their credibility in the industry.

Dangers Associated with FPE Breakers and Panels:

1. Failure to Trip: The primary function of a circuit breaker is to trip when there is an overload or short circuit, effectively shutting off the power supply to prevent fire hazards. It has been found that FPE breakers have an unacceptably high rate of failure – as high as 60% in some cases. This means that if a dangerous situation occurs, such as an electrical overload, the breaker may not trip, leading to a potentially catastrophic outcome. Various tests and lawsuits have confirmed this critical issue with FPE breakers.

2. Jams and Faulty Connections: Some FPE breakers are prone to jamming, which can happen when a breaker is not proportionally aligned within the panel. When a breaker jams, it may appear to be in the “off” position, when in fact, it is still providing power to the circuit. Besides posing a major safety risk, this can also damage electronic devices connected to the circuit. Furthermore, FPE Stab-Lok panels are infamous for their weak and unreliable connections, which can result in arcing and fires.

3. Mislabeled Breakers: FPE has been accused of intentionally mislabeling their breakers to meet the requirements of the Underwriters Laboratories (UL) for listing and approval. This misleading practice resulted in many FPE Stab-Lok breakers being used in applications for which they were not suitable, increasing the risk of malfunction and failure.

4. Age and Wear: The age of FPE breakers and panels is another significant factor contributing to their unreliability. With the majority installed between the 1950s and the 1980s, these components have likely experienced wear and tear, further exacerbating their already-existing safety issues.

What Home Inspectors Should Do:

As a home inspector, it is your duty to ensure the safety and well-being of the residents living in the properties you inspect. If you encounter an FPE panel or breaker during an inspection, take the following steps:

1. Document the presence of FPE components and inform the property owner of the potential risks.
2. Advise the property owner to hire a licensed electrician to perform a comprehensive evaluation of the electrical system.
3. Encourage the property owner to replace the FPE breakers and panels with modern, safer alternatives to reduce the risk of electrical hazards.

Conclusion:

FPE breakers and panels pose significant dangers that should not be overlooked during a home inspection. The high failure rates, coupled with faulty connections and misleading labeling practices, make them prime candidates for replacement. Ensuring the safety of homes and buildings is paramount, and taking appropriate action upon identifying FPE components can significantly reduce the risk of electrical mishaps.
