How to Tell If a Circuit Breaker Is Bad
Trip timing tells you everything: instant trips, trips after minutes, trips only with one appliance — each points somewhere different.
🔴 Emergency
Why Half Your House Lost Power
Lost leg vs. neutral failure — two very different causes. If any lights are getting brighter while others go dark: turn off the main breaker now.
⚠ Fire Precursor
Why Your AFCI Breaker Keeps Tripping
An AFCI isn't oversensitive — it detected arcing signatures your standard breaker would miss. Loose wiring, damaged cord, or failing LED driver.

🔴 Fire Risk
Why Your Outlet Is Warm or Hot
A warm outlet is a wiring fault in progress — loose connections heat up, damage insulation, and develop into arcing. Don't ignore warmth you can't clear by unplugging.
🔴 Shock Hazard
Why Shared Neutrals and MWBC Wiring Cause Flicker
Two breakers tripping together, or lights brightening on one circuit when another loads — the cross-circuit pattern that only an MWBC fault produces.

⚡ Pattern Guide
Why Lighting Hazards Develop
Lighting circuits are the home's electrical early warning system. Four hazard patterns — loose neutrals, overheating, arcing, moisture — each with distinct lighting symptoms.
🔴 Fire Risk
Why Recessed Lights Shut Off by Themselves
A light that cycles off and back on is overheating. The thermal limiter is preventing a fire — find out why it's tripping before the limiter fails.

Why Lights Flicker When Appliances Turn On
