Federal Pacific & Zinsco panel replacement in Chattanooga

Two panel brands common in Chattanooga homes built from the 1950s through the 1980s have a long record of breakers that may not trip when they should. Here's what that means for your home, your insurance, and your budget.

The concern

Why these panels get flagged

Breakers that may not trip

Federal Pacific Stab-Lok breakers have been widely reported to fail to trip under overload or short circuit - the one job a breaker has.

Loose bus connections

Zinsco and Sylvania-Zinsco panels are known for breakers that loosen or melt onto the aluminum bus bar, causing heat, arcing, and breakers that can't be removed.

Insurance trouble

Many insurers refuse to write new policies, add a surcharge, or non-renew homes with FPE or Zinsco panels. Home inspectors routinely flag them during a sale.

Cost

Typical Chattanooga replacement: about $1,500 to $3,500

Most panel swaps fall in this range. Where yours lands depends on a few things.

  • Panel size (100A vs 200A) and number of circuits
  • Whether the meter base or service entrance also needs work
  • Moving the panel or bringing old wiring up to current code
  • Permit, inspection, and EPB disconnect/reconnect coordination
  • Adding capacity now for an EV charger saves a second job later

How to spot one

  • Read the label inside the panel door: "Federal Pacific Electric," "FPE," "Stab-Lok," "Zinsco," or "Sylvania-Zinsco."
  • FPE Stab-Lok breakers often have red-tipped handles.
  • Zinsco breakers are thin and come in several colors - blue, red, green, tan.
  • Don't remove the cover. Only look at what's visible with the door open.
