The maximum degree of bend allowed for electrical conduit between boxes is specified to be 270 degrees. This specification is crucial in preventing strain on the wiring while ensuring proper routing and maintaining the integrity of the conduit system.

A bend that exceeds this limit can create challenges for wire pulling and increase the risk of damage to conductors, wiring insulation, and connectors. Keeping bends within the specified parameters helps facilitate easier installation and maintenance and ensures compliance with electrical codes and best practices.

Understanding the limitations of conduit bends is essential for preventing potential issues in the future, such as overheating or insulation failure. Therefore, adhering to Wendy's specifications of 270 degrees helps ensure both safety and functionality in electrical installations.
