What Is a Dual-Function Breaker?

Breaker BootCamp Study Guide

A dual-function breaker provides both AFCI and GFCI protection on one circuit.

It protects against fire and shock.

What It Does

A dual-function breaker detects:

• Arc-faults that cause fires

• Ground-faults that cause shock

All protection is applied at the panel.

Where It’s Used

• Circuits requiring both AFCI and GFCI protection

• Kitchens

• Laundry areas

• Code-driven residential circuits

One Critical Rule

Wiring defects and shared neutrals must be corrected first.

Dual-function breakers expose problems—they don’t create them.

Why Breaker BootCamp Teaches This

The Breaker BootCamp Study Guide teaches protection strategy early so the Breaker BootCamp course produces electricians who understand why protection trips instead of guessing or bypassing safety.
