What is the maximum that any conduit can be bent?

The maximum allowable bend for conduit is defined by the National Electrical Code (NEC), which specifies that the total angle of bends in a conduit run cannot exceed the equivalent of four quarter bends. Each quarter bend contributes 90 degrees of bend, making the maximum allowable bend effectively 360 degrees when considering four such bends in a configuration. However, bending conduits beyond this limit can create various issues, such as stress on the conduit and potential damage to the conductors inside.

This guideline helps ensure that electrical installations remain safe and code-compliant, promoting the proper functioning and longevity of wiring systems. When creating bends in conduit, it's crucial to adhere to these standards to prevent difficulties in pulling wires, which can arise from excessively bent conduits. This facilitates efficient installation and ongoing maintenance of electrical systems.
