A __________ shall be installed where cables emerge from raceway used for mechanical support or protection in accordance with code guidelines.

A __________ shall be installed where cables emerge from raceway used for mechanical support or protection in accordance with code guidelines.

• A. Bushing
• B. Junction Box
• C. Conduit
• D. Grounding Strap

Answer: (A)

The correct choice is the term that refers specifically to a protective fitting that covers the area where cables exit the raceway. In electrical installations, when cables run through a raceway, they can be vulnerable at the points where they exit. A bushing serves as a protective device to ensure that the cables do not get damaged from the edges of the raceway, reducing the risk of abrasion that could lead to potential shorts or electrical failures. Bushings are particularly effective in providing strain relief and protecting the insulation of the conductors as they transition from a rigid raceway to a more flexible cable. They help in maintaining compliance with safety and code requirements, ensuring that installations are secure and reliable. In contrast, a junction box is used to join multiple electrical connections or circuits but does not specifically address protection at the entry/exit points of raceways. A conduit is a type of raceway itself, providing mechanical protection but not necessarily a fitting for the transition point. A grounding strap is related to grounding systems, ensuring proper electrical bonding and grounding, but does not serve the same protective function for cables exiting raceways. Thus, the term that indicates a fitting designed for this specific protective purpose at the cable exit point is accurately identified as a bushing.
