Welcome to our blog!
We want you to be an informed homebuyer, and each blog post is a question that we have answered for our friends and customers over the years. Hope they help you make a good choice for your next home.

     To view a report by about the history and hazards of Federal Pacific panels by J. Aronstein, a consulting engineer that specializes in mechanical and materials testing, click on this link: Aronstein’s evaluation of the panels is that they represent a “safety defect,” and that replacement is the only practical and safe solution.

     If you open the door of an electric panel in a house you are considering buying and find the words “STAB-LOK” or “FPE”—like in the two photos below—it’s reasonable to expect that the panel poses a potential safety risk and will likely decrease the value of the home in the current marketplace. Also, some insurance companies will not write a homeowner’s policy on a house with a Federal Pacific Stab-Lok panel.

    Another electric panel from the same era that has a checkered history is Zinsco, although the standard recommendation for this panel is evaluation by an electrician. It was also sold under the names Sylvania-Zinsco and Kearney. To read more about the Zinsco panel, see our blog post “Why are Zinsco and Sylvania-Zinsco electric panels a problem?”

While we hope you find this series of articles about home inspection helpful, they should not be considered an alternative to an actual home inspection by a local inspector. Also, construction standards vary in different parts of the country and it is possible that important issues related to your area may not be covered here.
