Which of the following is a requirement for pulling conductors into a raceway?

The requirement related to pulling conductors into a raceway that is most crucial is that the conductors must be within certain size limits. This is important to ensure that the conductors can be safely and effectively installed within the raceway without causing damage to the conductors or violating electrical codes.

Conductors have specific size limits based on their type and the size of the raceway. If the conductors exceed the allowed size for the raceway, it could lead to difficulty in pulling and increased risk of insulation damage due to excessive tension. Moreover, if the raceway is too small relative to the number and size of conductors, it could also hinder proper heat dissipation, potentially leading to overheating situations.

While there are other factors related to raceway installation, such as the need for raceways to be labeled or certain dimensional requirements, these are not as directly related to the physical act of pulling conductors into the raceway itself. Understanding these size limitations is essential for compliance with safety standards and effective electrical installation practices.
