Is it acceptable to use a junction box or a raceway to feed conductors through or tap off to other switches?

Using a junction box or a raceway to feed conductors through or to tap off to other switches is indeed acceptable under the National Electrical Code (NEC) guidelines. Junction boxes are specifically designed to house electrical connections and provide a safe environment for branching circuits or making splices. They ensure that electrical connections are protected from damage and that heat can dissipate properly, reducing the risk of overheating and fire.

Raceways also facilitate the safe routing of conductors, protecting them from physical damage while maintaining clear pathways for electrical distribution. Both junction boxes and raceways play critical roles in ensuring electrical systems are organized, safe, and compliant with code requirements.

It's important to follow appropriate installation practices and ensure that both junction boxes and raceways are properly sized for the number and size of conductors used. Additionally, they must be accessible for maintenance. This compliance with NEC standards helps ensure safety and reliability in electrical installations.

In contrast, not all options reflect the positive acceptance of using junction boxes or raceways universally. There are circumstances under which additional conditions might apply, which may lead to confusion. However, the general stance remains that the use of junction boxes and raceways for feeding conductors is fully permissible and a standard practice in electrical installations.
