In accordance with code, how should conductors be connected to prevent issues in a terminal or splicing connector?

Selecting one type of metal for conductors is essential for preventing galvanic corrosion and ensuring reliable electrical connections. When conductors made from different metals are connected, such as copper and aluminum, a chemical reaction can occur, leading to corrosion at the junction. This can increase resistance, cause potential overheating, and ultimately lead to failure of the connection.

Utilizing a single type of metal throughout the circuit ensures compatibility and minimizes the risk of such issues. For instance, if the entire circuit is copper, all conductors and connectors should be made of copper, which maintains uniformity and reduces the possibility of corrosion-related problems.

In addition to this, proper identification of conductors is also a critical aspect, but it serves a different purpose; it relates to safety and ensuring that the connections are made according to code and labeling standards rather than directly preventing terminal or splicing issues. Other options that suggest using unbonded systems or solely aluminum conductors do not address the material compatibility issues effectively.
