All conductors of the same circuit, including grounded and bonding conductors, shall be contained within the same ________, unless permitted otherwise.

In electrical installations, it's crucial to ensure that all conductors of the same circuit remain within the same pathway for several reasons. By requiring that all conductors, including grounded and bonding conductors, be contained within the same raceway or cable, it promotes a coordinated and organized installation, minimizes the risk of electromagnetic interference between conductors, and enhances safety by preventing accidental contact with other circuits or grounding paths.

Using a raceway or cable helps protect conductors from physical damage and environmental factors, ensuring their longevity and reliability. The allowance for certain exceptions emphasizes flexibility in adhering to specific installation configurations while still maintaining overall safety and functional integrity.

Thus, understanding that all conductors must be within the same raceway, cable, or trench harmonizes with electrical codes and standards aimed at ensuring the safe operation of electrical systems.
