1. Federal Pacific
Federal Pacific electrical panels are commonly found in homes built between 1950 and 1980. They have been reputed for years for having a high breaker failure rate, causing house fires and electrical shocks.
Zinsco electrical panels were put into homes throughout the 1970s, and not all of the homes built during this decade have upgraded boards. Unfortunately, these electrical boards are unable to keep up with today’s electricity outputs, which results in melted wires, electrical fires, and electrical shocks.
Challenger electrical panels were installed in homes and buildings during the 1980s and 1990s. Unfortunately, two types of panels made by Challenger are faulty, overheating while under normal conditions.
