When it comes to home safety, one of the most critical components to inspect is your electrical service panel. Unfortunately, certain brands of service panels, such as Zinsco, Sylvania, Federal Pacific, and Stab-Lok, have been identified as problematic due to their potential fire hazards. In this blog post, we’ll delve into the issues associated with these service panels and why it’s crucial to address them promptly.
Zinsco Service Panels

Some of the issues include insecure connections between breakers and bus bars, components made of aluminum that corrode easily, and breakers that can melt into the bus bar. Additionally, Zinsco panels may continue to conduct electricity even when the breaker appears to be off. Due to these safety concerns, it’s highly recommended to replace Zinsco panels with modern, safer alternatives.

Federal Pacific Electric (FPE) Stab-Lok panels were widely used from the 1950s to the 1980s. These panels have a notorious reputation for failing to trip when a circuit is overloaded, which can lead to overheating and potential fires.
