How many conductors can be wrapped around a screw terminal?

• A. 1
• B. 2
• C. 3
• D. 4

Answer: (A)

The correct response indicates that only one conductor should be wrapped around a screw terminal. This is an important safety and functionality consideration in electrical work. When a single conductor is properly attached to a screw terminal, it ensures a secure and reliable electrical connection, minimizing the risk of loose wires which could lead to arcing or overheating. Using more than one conductor on a screw terminal can lead to several issues. For example, if multiple wires are bundled together and either tightened insufficiently or not properly aligned, it can create a poor connection, potentially leading to electrical failures. Furthermore, from a regulatory standpoint, electrical codes often specify that only a single conductor may be attached to a screw terminal to ensure safe and dependable operations. Thus, wrapping only one conductor around a screw terminal is a best practice that promotes effective and safe electrical installations.
