What is wrong with FPE and Zinsco electrical panels?

Federal Pacific Electric (FPE) Stab-Lok and Zinsco panels show up in homes built or remodeled from roughly the 1950s into the 1980s, exactly the era of many Coon Rapids ramblers and splits, and both have a documented safety reputation. The core concern is that their breakers can fail to trip during an overcurrent or short. A breaker that doesn't trip means the circuit keeps drawing current and overheating, which is a fire risk. Zinsco panels can also suffer from bus bars that corrode or melt where breakers connect. These aren't always a hard code violation, but most inspectors and electricians flag them as a latent safety hazard and recommend replacement by a licensed electrician rather than patching. If we find an FPE or Zinsco panel during your inspection, we'll document it clearly with photos so you can budget a panel upgrade or use it in negotiations. A modern panel swap is a well-understood job for a local electrician. Don't ignore one of these just because the lights work; the danger is hidden. Want your panel checked before you buy?
