What Is an AFCI Breaker?

Breaker BootCamp Study Guide

An AFCI breaker protects against arc-faults that can cause electrical fires.

It is designed for fire prevention, not shock protection.

What It Does

An AFCI breaker detects dangerous arcing conditions in branch-circuit wiring and shuts off power before ignition occurs.

Where It’s Used

• Bedrooms

• Living areas

• Residential branch circuits requiring arc-fault protection

One Critical Rule

Nuisance tripping usually indicates a wiring problem, not a bad breaker.

Oversizing or bypassing AFCI protection is never the fix.

Why Breaker BootCamp Teaches This

The Breaker BootCamp Study Guide teaches students to understand arc-fault behavior early so the Breaker BootCamp course focuses on diagnosing real wiring issues instead of blaming protection devices.
