What does a splice do in electrical work?

A splice in electrical work serves the critical function of connecting two pieces of cable both electrically and mechanically. By creating a splice, electricians ensure that the electrical circuit remains continuous and that the connection can withstand various mechanical stresses. This involves properly aligning and joining the individual wires, often using connectors, heat shrink tubing, or soldering techniques to establish a reliable electrical pathway.

While enhancing signal quality, insulating wires, and protecting against overheating are important aspects of electrical work, they do not specifically define the primary role of a splice. A splice's main purpose is to maintain the integrity of an electrical circuit by securely joining wires, allowing for the smooth transmission of electricity through the system.
