What is the primary use of cable splicing in line work?

Cable splicing in line work is primarily used to join two or more lengths of wire or cable. This process is crucial because it maintains the continuity of the electrical circuit, ensuring that electricity can flow uninterrupted through the connected cables. When two sections of cable need to be linked, splicing provides a secure and reliable connection that minimizes the risk of electrical failures or disruptions in service.

Other options, while related to cable maintenance, serve different purposes. Removing damaged sections of cable is a necessary procedure when safety or functionality is compromised, insulating connections is important for protecting against electrical hazards, and tracking the length of cable used on a job pertains to project management rather than the primary function of splicing. The essential goal of splicing is to ensure a seamless electrical connection, which is why this option is the primary use in line work.
