How many conductors may be wrapped around a screw terminal?

  1. 1

  2. 2

  3. 3

  4. 4

The correct answer is: 1

The correct answer indicates that only one conductor is permitted to be wrapped around a screw terminal. This aligns with electrical safety standards, which advocate for a single conductor connection to ensure a secure and reliable electrical connection. When a screw terminal is designed for a single conductor, wrapping multiple conductors can lead to several issues, including poor conductivity, overheating, and potential failures in the electrical system. Additionally, using more than one conductor can compromise the integrity of the connection, creating a safety hazard due to loose or inadequate connections. Consequently, following this guideline ensures the effectiveness of the electrical installation while minimizing the risk of malfunctions.
