Breaker BootCamp Study Guide


12/2 NM cable is used for 20-amp branch circuits.


It contains two insulated conductors and a grounding conductor.





What It Does



12/2 NM carries power for higher-load residential circuits where 20 amps is required.





Where It’s Used



  • Kitchen small-appliance circuits

  • Bathroom circuits

  • Garage receptacle circuits






One Critical Rule



Breaker size must match the conductor size.

12/2 NM = 20 amps. No exceptions.





Why Breaker BootCamp Teaches This



The Breaker BootCamp Study Guide locks in conductor-to-breaker matching early so the Breaker BootCamp course avoids overheated wires, nuisance trips, and unsafe upgrades.
