What is a re-entrant bend in conduit installation?

A re-entrant bend in conduit installation specifically refers to a bend that directs the conduit back at an angle, allowing it to navigate around obstacles or change direction in a way that maintains an effective routing of the electrical or telecommunications pathways. This type of bend is particularly useful in ensuring that the conduit installation remains tidy and complies with design requirements by minimizing stress on the conduit and maximizing the efficiency of the installation.

The utility of a re-entrant bend lies in its ability to redirect the conduit without requiring extensive straight runs of conduit, which might not be practical in all installation scenarios. This makes it an essential technique for installers who must adapt to the physical environment while maintaining proper conduit placement.

Other choices do not accurately reflect the definition of a re-entrant bend, as they either describe different formations or do not pertain to the specific function of adjusting conduit direction.
