The first bend in an offset bend must be made at what angle?

The correct angle for the first bend in an offset bend is 45 degrees, as this provides a good balance between a gentle transition and the necessity for maintaining the physical integrity and structural stability of the conduit. A 45-degree bend allows the conduit to change direction effectively while minimizing stress along the length of the pipe, ensuring ease of installation and proper alignment in various applications.

Using 45 degrees strikes a balance between sharpness and smoothness in conduit runs. Bends that are too sharp, like a 90-degree angle, could increase the risk of damage or kinking in the conduit when wires are pulled through. Additionally, other angles such as 30 degrees or 60 degrees may not fit specific needs for offset bends that require a more pronounced change in direction while preserving efficiency in installation and maintenance. Therefore, 45 degrees is the industry standard for the first bend in an offset, allowing for optimal performance and longevity of the electrical system being installed.
