Your panel is the one device that must never fail silently. After 12,000+ California jobs, these are the seven signs that mean 'call this week, not next year'.
The 7 Warning Signs
- Federal Pacific (FPE Stab-Lok) or Zinsco label — documented high failure-to-trip rates; insurers increasingly flag them. Replacement, not repair.
- Warm, buzzing or burning-smell panel — loose lugs overheating. Do not touch; call immediately.
- Breakers trip weekly — the circuit is overloaded or the breaker is dying.
- Rust, moisture or scorch marks — corrosion raises resistance and fire risk, common near coasts.
- 100A service with EV + AC + induction — the math no longer works; a 200A heavy-up is due.
- Fuses instead of breakers, or double-tapped breakers — outdated or improper wiring methods.
- No main breaker or no labeling — emergency shutoff confusion when seconds matter.
What an Upgrade Costs & Involves
In California, most 200A upgrades run $1,900-$4,800, take one day, and include permit, inspection, utility coordination, surge protection and labeling. Send us a photo of your panel for a fast remote opinion.
Frequently Asked Questions
Not always tonight — but it belongs at the top of your list. If you also notice heat, smell or frequent trips, treat it as urgent.
On FPE/Zinsco equipment, replacement breakers are costly and the bus design remains the risk — full replacement is the honest fix.
Typically 4-8 hours during the swap; we schedule utility cutovers to minimize downtime.
