Which of the following bending configurations is permitted in conduit runs?

The correct answer highlights an acceptable bending configuration that maintains compliance with conduit bending standards and best practices in electrical installations.

In conduit work, the maximum number of bends in a run is typically limited to ensure proper installation and device access, as too many bends can make wire pulling difficult or even impractical. The framework of this question assesses the ability to understand how to combine different bending techniques effectively.

The configuration described in the correct answer consists of a combination of bends that is not only permissible but practical for maneuvering conduit in a space-constrained environment. Using two 90-degree bends allows for a significant directional change, while the addition of a one-45-degree bend and a one-12-degree offset facilitates further adjustments to the conduit without overly complicating the route. The three-point saddle also serves to mitigate stress on the cable while allowing for a smooth transition in direction. All these types of bends are usable within the limits set by the National Electrical Code (NEC) as long as they do not exceed the maximum bending length allowed for the conduit type used.

This thoughtful combination of bends maintains electrical code compliance while providing the flexibility needed during installation, making it an ideal choice in practice.
