Is Your Electrical Panel Dangerous? Federal Pacific and Zinsco

If your North Idaho home was built or updated between roughly the 1950s and the 1980s, there is a real chance it has an electrical panel that the industry now considers unsafe. Two brands in particular, Federal Pacific Electric (FPE) Stab-Lok and Zinsco, are well known among electricians for breakers that can fail to trip during an overload or short. A breaker that does not trip is the whole safety system failing silently, and that is a fire risk.

Why these panels are a problem

A circuit breaker has one critical job: to shut off power when a circuit draws too much current. Independent testing and decades of field experience have shown that Federal Pacific Stab-Lok and Zinsco breakers can fail to trip far more often than they should, and that they can be damaged by the heat of repeated faults. Because the panel looks fine from the outside, most homeowners have no idea there is an issue.

Warning signs to watch for

• A Federal Pacific or Zinsco label on the panel or breaker handles

• Breakers that will not stay reset

• A burning or hot-plastic smell, or warm spots on the panel

• Buzzing, scorch marks, or flickering that affects the whole house

What to do about it

The fix is a panel replacement, swapping the unsafe panel for a modern one with reliable breakers and room for today's loads like EV chargers and hot tubs. We replace panels across Coeur d'Alene, Hayden, Post Falls, Rathdrum, Liberty Lake, and Spokane Valley, handling the permit, the utility coordination, and clean, labeled, code-compliant work.

Frequently asked questions

Should I replace a Federal Pacific or Zinsco panel even if it works? Most electricians recommend replacement, because the danger is exactly that it appears to work until it does not trip when it matters.

How long does a panel replacement take? Often a single day, depending on the service and any upgrades.

Will I lose power during the work? Briefly. We coordinate the shutdown and restore power the same day.
