To avoid violating the NEC®, what is the maximum degree saddle that can be made while making 22.5° offsets?

• A. I only
• B. I or II only
• C. I or II or III
• D. none of these

Answer: (D)

To determine the maximum degree saddle that can be created while making 22.5° offsets, it is essential to understand how these angles interact in a conduit system as defined by the National Electrical Code (NEC®). In conduit bending, a saddle is typically formed by making three bends; a 22.5° offset would be one method to address directional changes while maintaining a level of flexibility in routing the conduit. The total degree of bend for a saddle should not exceed certain limitations to avoid compromising the integrity of the installation. As outlined in the NEC®, making a saddle with a combination of bends needs careful consideration. While the individual offsets might be 22.5°, the cumulative angle additively influences the overall length of the conduit and how it is supported and managed through its path. If a saddle exceeds certain degrees, it may create issues related to pulling wire or fitting into spaces, thereby not complying with the NEC®. In this case, stating that none of the configurations (as indicated in the options) comply means that even the idea of having configurations that include 22.5° offsets presents challenges related to exceeding practical bending standards for saddles within the NEC® guidelines. Thus, ultimately, there isn't an allowable maximum degree saddle
