Which type of wire is primarily used for grounding in low-voltage systems?

• A. Bonding wire
• B. Shield wire
• C. Ground wire
• D. Drain wire

Answer: (C)

The type of wire primarily used for grounding in low-voltage systems is ground wire. This wire is specifically designed to provide a conductive path for fault currents, allowing electricity to safely return to the ground, which helps to prevent electrical shocks and equipment damage. Ground wires are typically made of copper or aluminum and are often insulated or bare depending on the application. In low-voltage systems, the grounding process is essential for protecting both equipment and users from electrical hazards by directing excess electricity safely into the earth. Ground wires ensure that any stray currents can be effectively dissipated. Other types of wires mentioned, such as bonding wire, shield wire, and drain wire, have different purposes. Bonding wire is used to connect various metal parts to ensure that they are at the same electrical potential. Shield wire provides electromagnetic shielding for signal integrity, particularly in data cables. Drain wire serves to ground the shield in shielded cables, but it does not function as the main grounding wire for low-voltage systems. Thus, the ground wire is the correct choice for this application.
