Breaker BootCamp Study Guide


An electrical junction box encloses splices and terminations.


It provides protection and access.





What It Does



A junction box contains wire connections so they are:


  • Protected from damage

  • Accessible for service

  • Properly enclosed






Where It’s Used



  • Splice points

  • Wiring transitions

  • Conduit terminations






One Critical Rule



All splices must be inside an accessible junction box.

No buried boxes. No exceptions.





Why Breaker BootCamp Teaches This



The Breaker BootCamp Study Guide teaches enclosure rules early so the Breaker BootCamp course avoids hidden splices, failed inspections, and unsafe wiring practices.
