Homes throughout Portland, Beaverton, Tigard, and Hillsboro still contain older electrical panels that were installed decades ago. Two brands in particular — Federal Pacific Electric (FPE) and Zinsco — are known industry-wide as unsafe and are commonly flagged by home inspectors and insurance companies.
If you’ve discovered that your home has one of these panels, here is everything you need to know.
Why FPE & Zinsco Panels Are Considered Unsafe
1. Breakers Fail to Trip (The Biggest Danger)
Breakers exist to stop power during overloads.
Tests show:
- 60–80% of FPE Stab-Lok breakers fail to trip
- Zinsco breakers can melt to the bus bar and stay stuck ON
This creates a major electrical fire risk.
2. Hidden Internal Damage
Even when they look fine on the outside, these panels often have:
- Melted bus bars
- Loose breakers
- Burnt wiring
- Corrosion from age and heat
Most homeowners never know something is wrong until a breaker overheats.
3. Insurance Companies Flag Them
Many insurance providers in Oregon will:
- Deny coverage
- Refuse renewals
- Require immediate replacement
This is especially true for homes in Laurelhurst, Cedar Mill, and NE Portland’s older neighborhoods.
Signs You Might Have a Problem
Call an electrician if you notice:
- Warm or buzzing panel
- Breakers tripping randomly (or never tripping at all)
- Lights flickering when appliances run
- Burning smell near the panel
- Discoloration or scorch marks
Even one of these symptoms is enough to schedule an inspection.
Cost to Replace an FPE or Zinsco Panel in Portland
Most replacements cost:
➡ $3,000–$6,500
depending on:
- Panel size (100A, 150A, 200A)
- Meter and service mast condition
- Indoor vs outdoor location
- Whether utility coordination is needed (PGE / Pacific Power)
Smiley Electric provides a full in-person inspection before recommending the correct replacement.
Repairing Them Is NOT Recommended
Because these panels are unsafe by design, repairs don’t solve the underlying hazard.
Most electricians – including Smiley Electric – recommend full replacement.
Portland Homes Most Commonly Affected
These panels were heavily installed in homes built between 1950–1985, especially in:
- Beaverton (Cedar Hills, Vose, Raleigh West)
- NE Portland
- Tigard
- Lake Oswego
- Hillsboro
If your home is from this era, your panel should be inspected.
