When is a conduit bend considered a "hard bend"?

A conduit bend is considered a "hard bend" when it changes direction by 90 degrees without a gradual curve. This definition is rooted in the physical characteristics of the bend, where the abrupt change in direction can lead to potential restrictions for wiring pulling through the conduit and may also affect the integrity of the conduit itself.

In practical applications, conduit bends must be designed to allow for effective installation and maintenance of electrical wiring or cables. The sharper angle of a hard bend creates a more challenging pathway, as compared to gentle or gradual curves that facilitate smoother transitions.

Understanding the distinctions in bends helps in ensuring compliance with installation codes and practices, promoting safety and efficiency in electrical systems. While other options touch on aspects of bending, they do not classify the bend as a hard bend based on the established definitions used in conduit installations.
