1. Check for 36" clear workspace in front of the panel (no storage blocking access)
2. Open panel — look for any signs of scorching, melted plastic, or discoloration
3. Check for double-tapped breakers (two wires on one breaker — usually not permitted)
4. Verify circuit labels are legible and accurate
5. Check for recalled breaker brands (Federal Pacific, Zinsco)
6. Verify main breaker size matches service
7. Check for any open knockouts (holes in the panel — fire and shock hazard)
8. Look for aluminum wiring (silver-colored wire at breakers — if present, needs evaluation)
