The electrical code requires that how many bare conductors can be connected to a screw terminal?

The electrical code specifies that only one bare conductor can be connected to a screw terminal. This regulation is in place mainly for safety reasons, as allowing multiple conductors to attach to a single screw terminal can lead to increased resistance, overheating, or the potential for a loose connection. A single conductor ensures a stable and secure electrical connection, facilitating proper operation and reducing the risk of electrical malfunctions.

In instances where multiple conductors need to be connected, alternative methods such as terminal blocks or wire nuts are recommended. These methods allow for safe and effective junctions while adhering to the code's requirements.
