In addition to pulling in conductors, what internal function do conductor pulling tapes provide?

Conductor pulling tapes serve several important functions beyond merely facilitating the pulling of conductors through conduits. One significant internal function of these tapes is measurements. These tapes often have markings that allow electricians and contractors to measure the length of cable or conduit that is being installed. By providing precise measurements, the tapes help ensure that the right amount of conductor is pulled and that installations are performed accurately, avoiding the risks associated with excess or insufficient cabling.

This capability is particularly important in complex installations where the distances can vary significantly, and accurate measurements are crucial for maintaining system integrity and efficiency. While other options might seem relevant in different contexts, they do not pertain directly to the primary internal function of conductor pulling tapes. For example, airtight seals and insulation pertain to the external properties and protection of conductors, while cable width would be related to the design specifications of the cable itself rather than the functional aspects of the pulling tape.
