Identify the label
Start with clear documentation
Panel labels, door markings, and circuit directories help route the right assessment.
- Photograph the label and panel exterior.
- Include meter-area photos.
- Do not remove the cover.
FPE and Zinsco Panel Replacement
Start here when the label is unclear or an inspection report lists FPE and Zinsco together. Identify whether the equipment is Federal Pacific/Stab-Lok, Zinsco, or Sylvania-Zinsco, then continue to the matching brand guidance for replacement planning.

Identify the label
Panel labels, door markings, and circuit directories help route the right assessment.
Keep histories separate
The two brands should not share a fabricated recall or a single safety claim.
Plan replacement scope
Circuits, service capacity, access, and future loads shape the work.
Photos can help identify a label and prepare a visit, but they cannot establish internal breaker performance. The assessor needs the actual service arrangement, accessible equipment, circuit needs, and conditions at the property.
For smoke, active arcing, or immediate danger, move away from the equipment and call 911.
CPSC closed its Federal Pacific investigation without making a safety determination. Its notice is not a recall and does not certify an individual panel. The FPE route explains those limits in detail.
The NC Home Inspector Licensing Board cites documented Zinsco breaker and busbar concerns and recommends a licensed electrical-contractor evaluation, because identifying latent conditions may require invasive work beyond a home inspection. This is separate evidence from FPE history.
The FPE and Zinsco pages provide brand-specific detail. A panel replacement, service upgrade, subpanel, grounding/bonding review, and future-load project can overlap but they solve different problems. The proposal should state which scope fits the house.
Photograph the closed door, manufacturer label, breaker labels visible without removing the cover, circuit directory, meter area, and any inspection note. Use daylight and include a wider view so the equipment location and access are clear. Do not remove the cover, pull breakers, or try to read hidden markings.
Manufacturer labels and individual breaker labels can differ when equipment has been altered over time. That is a reason to document both, not to assume that a replacement breaker proves the panel assembly is current or suitable. The brand-specific routes retain the different FPE and Zinsco evidence instead of combining them into one claim.
From our field photos
This separate field photograph shows the label and breaker arrangement of Federal Pacific Stab-Lok equipment. The manufacturer and equipment markings help direct the review to the correct replacement service. A homeowner can share accessible exterior labels and any inspection report. An electrician handles the internal equipment review.
The combined route identifies the equipment and sends the homeowner to brand-specific evaluation rather than merging the histories.
Send labels, exterior and meter photos, and inspection notes.
Separate FPE/Stab-Lok and Zinsco questions.
Assess panel, service, circuits, and required approvals.
No. They are different product histories and should be evaluated using the relevant evidence and the actual installation.
Often it can help identify a label, but it cannot confirm internal condition.
No. It does not make a recall claim for either brand.
Use the FPE replacement page for Federal Pacific or Stab-Lok equipment and the Zinsco replacement page for Zinsco or Sylvania-Zinsco equipment.
Share your city, the work you need, and any equipment or plans you already have.
