Challenger Electric Panels is a brand that was once owned by the Federal Pacific Electric Company (FPE), which was a manufacturer of electrical equipment and systems. The brand was widely known for its residential circuit breaker panels, which were sold in the United States from the 1960s to the 1980s.
Today, Challenger Electric Panels are no longer produced and the brand no longer exists as a separate entity. However, there are still some homes and buildings that have Challenger panels installed, and homeowners are advised to have them inspected by a licensed electrician to ensure they are functioning safely and effectively. It's important to note that there are many other reliable and safe options available for residential circuit breaker panels.
