In surface metal raceways without removable covers, where are splices allowed in conductors?

In surface metal raceways without removable covers, splices in conductors are permitted in boxes or junction boxes. This is essential because junction boxes provide a safe and accessible place for making splices, ensuring that connections are secure and protected. They also allow for maintenance and modifications without needing to disturb the entire raceway system.

The use of junction boxes is in line with electrical codes which prioritize safety and accessibility. These boxes serve as enclosures that safeguard electrical connections from physical damage, dust, and moisture while providing adequate space for technicians to work with the connections. By limiting splices to these boxes, the installation adheres to best practices for low-voltage special systems, promoting both functionality and safety.

In contrast, making splices in any random accessible location or in areas without protective enclosures would pose significant safety risks and lack compliance with electrical standards. Additionally, conducting splices outside of designated boxes can lead to complications in troubleshooting and future modifications, as well as increased risk of faults or failures in the wiring system.
