What is the total length of multi-conductor wire needed for a pull between a starter and a 3-phase motor with given tails?

To determine the total length of multi-conductor wire needed for the pull between a starter and a 3-phase motor, one must consider the distance between the starter and the motor, as well as the additional length required for making connections, including tails for proper terminations at both ends.

In typical scenarios, the total length required involves not just the linear distance but also considerations for wire management and slack. Therefore, the final length of 81 feet reflects the straight-line distance plus any necessary extra length for connections and flexibility during installation.

When calculating for a multi-conductor system like a 3-phase motor setup, each of the three conductors must be properly accounted for along with a possible ground wire. The figure of 81 feet likely includes room for these considerations, ensuring that the installation is practical and adheres to industry standards.

This comprehensive understanding of the necessary factors leads us to the conclusion that 81 feet is the most appropriate answer for adequately covering the wiring requirements in this context.
