Breaker BootCamp Study Guide


A two-pole breaker protects two ungrounded conductors and disconnects them simultaneously.


It is required for 240-volt loads and certain shared-neutral circuits.





What It Does



A two-pole breaker supplies 240V or protects a multi-wire branch circuit by tripping both poles at the same time.





Where It’s Used



  • Water heaters

  • Dryers and ranges

  • HVAC equipment

  • Multi-wire branch circuits






One Critical Rule



Two single-pole breakers are not a substitute.

Both conductors must disconnect together.





Why Breaker BootCamp Teaches This



The Breaker BootCamp Study Guide teaches breaker selection based on circuit intent, so the Breaker BootCamp course avoids unsafe servicing conditions and incorrect panel work.
