Electrical Panels Commonly Flagged for Replacement
Many homeowners are unaware that certain electrical panels have a documented history of breaker failure, overheating, or unsafe operation. These panels may appear to function normally while posing hidden safety risks.
If your home has one of the panel types listed below, a professional evaluation is strongly recommended.
⚠️ Panels Commonly Flagged for Replacement
Federal Pacific (FPE / Stab-Lok)
Federal Pacific Electric panels are widely known for breakers that may fail to trip during overloads or short circuits, increasing the risk of electrical fires. These panels are commonly flagged during home inspections and insurance reviews.
Zinsco / Sylvania Zinsco
Zinsco panels are known for bus bar corrosion and breakers that can fuse to the panel. This can prevent breakers from tripping properly and make safe servicing difficult or impossible.
Challenger (Certain Models)
Some Challenger panels have documented issues with breaker failure and overheating, particularly under higher electrical loads.
Pushmatic (Bulldog)
Pushmatic panels use an outdated breaker design with limited replacement parts availability. While some remain operational, they do not meet modern safety expectations and can be difficult to service safely.
Split-Bus Panels
Split-bus panels are an older configuration that does not include a single main disconnect. While they were once code-compliant, they are outdated by modern safety standards and often lack capacity for today’s electrical demands.
Why This Matters
Panels on this list may continue operating while silently failing under load. Replacing them can:
Improve electrical safety
Reduce fire risk
Prevent insurance or resale issues
Increase capacity for modern appliances and upgrades
Not every panel automatically requires replacement — condition, load, and usage all matter.
