When splicing transmission conductors/wires, how far should a conductor be laid in each direction before splicing?

When splicing transmission conductors or wires, it is essential to lay a sufficient length of conductor in each direction to ensure proper tension and alignment during the splicing process. The recommended practice is to lay out 40 feet of conductor in each direction before making the splice. This length allows for enough wire to accommodate the necessary movement and adjustments while maintaining the structural integrity of the splice.

Having a longer length of conductor also helps in facilitating the proper tools and techniques for the splice, ensuring the joint remains secure and lessening the chance of stress on the connection. This standard distance also plays a crucial role in achieving the desired electrical and mechanical properties of the splice, contributing to the overall reliability and safety of the electrical system.

The other options do not provide sufficient length for effective splicing, which can lead to poor connection quality or physical stress on the wires, making them less suitable for this application.
