Which section provides guidelines for how bends are made in metal conduits in the NEC?

The guidelines for how bends are made in metal conduits can be found in Section 358.28 of the National Electrical Code (NEC). This section specifically addresses the requirements for bends and offsets in metal raceways, including conduit. It lays out the acceptable methods and techniques for creating bends in metal conduits to ensure that they are done safely and effectively, allowing for proper function and installation.

Choosing this section is important in promoting safe electrical practices, as correct bends can significantly impact the integrity and longevity of electrical installations. The appropriate understanding of conduit bending helps prevent mechanical stress that could lead to damage, ensuring that the electrical conductors inside are also protected.
