Where shall splices and taps be made in surface metal raceways without removable covers?

Splices and taps in surface metal raceways without removable covers must be made only in boxes to ensure safety and accessibility for inspection and future maintenance. Junction boxes provide a designated and secure environment for making electrical connections, helping to protect the splices from damage and strain. Additionally, making splices within the confines of a box allows for proper sealing and ensures compliance with electrical codes, which often mandate that connections be made in accessible locations to facilitate future work on the electrical system. This approach also aids in minimizing potential hazards, keeping splices secure from external disturbances that could cause a failure or create unsafe conditions.
