How far apart can two junction boxes be connected using bends permitted by the NEC®?

The correct answer indicates that the distance between two junction boxes connected by bends is contingent upon adhering to the bend limit specified by the National Electrical Code (NEC®). The NEC outlines specific requirements for how bends can be made in conduit and cable, ensuring that the bends do not exceed the allowable degree of curvature that would impede proper functioning or mechanical integrity.

The regulations ensure that when making bends, the radius does not become so tight that it risks damaging the cable or conduit inside. Thus, as long as the installation meets these bend limits and does not violate any other code provisions, there is no strict variably prescribed distance. This flexibility allows electricians to design layouts that best fit the physical space while still adhering to safety and performance standards.

This approach emphasizes the importance of understanding the NEC guidelines thoroughly to ensure that all installations are safe and compliant, allowing for creative problem-solving as long as the essential rules are followed.
