What does the NEC state about the splices, joints, and terminations of conductors?

The National Electrical Code (NEC) stipulates that splices, joints, and terminations of conductors must be made in a manner that ensures good mechanical and electrical continuity. This requirement is crucial because it ensures the reliability and safety of the electrical system. Good continuity ensures that electrical connections can effectively carry current without overheating or failing, which could lead to electrical fires or equipment malfunctions.

Furthermore, establishing a sound mechanical connection prevents the physical separation of conductors over time due to vibration or thermal expansion. This means that proper techniques must be used in making these connections, such as using appropriate connectors, soldering, or other accepted methods that comply with the NEC guidelines.

Prioritizing effective connectivity contributes to the overall performance and safety of electrical systems in various installations, from residential to industrial applications.
