Insurance-required repair
Your insurer flagged a Federal Pacific (Stab-Lok), Zinsco, or Sylvania panel on a 4-point or underwriting inspection and is threatening non-renewal or cancellation unless it is replaced.
Carriers flag Federal Pacific Stab-Lok and Zinsco panels because of a documented history — including independent lab testing and decades of field reports — of breakers that may fail to trip, which underwriting treats as a fire risk. A 4-point inspection at renewal or on a new policy commonly surfaces it.
Use the location where the work will be permitted and inspected. If your city is not listed, start a request anyway.
No. Replacement commonly clears the underwriting flag, but each carrier sets its own rules and no contractor can promise a specific carrier will reinstate or keep coverage. Keep your permit, invoice, and final inspection so your agent can submit them.
Yes. Some carriers will decline, nonrenew, or require replacement when a 4-point inspection or underwriting review identifies a Zinsco, GTE-Sylvania, Federal Pacific, FPE, or Stab-Lok panel. The exact rule depends on the carrier, state, policy program, and property, so get the requirement in writing before spending money.
Sometimes, but it is harder once the panel is flagged. Some carriers may write the policy with a deadline, exclusion, proof requirement, or replacement condition; others may decline until the panel is replaced and documented. Ask the agent what proof underwriting needs: permit, invoice, final inspection, updated 4-point, photos, or an electrician letter.
A code official may not force every older Federal Pacific panel to be replaced immediately, but many insurers treat FPE and Stab-Lok panels as an underwriting risk. If your carrier names it in a letter or inspection condition, assume they want documented replacement unless they confirm another option in writing.
