What type of connection is permitted for #10 or smaller conductors?

The permitted connection for #10 or smaller conductors includes the use of binding screws or studs with unturned lugs. This specific method of connection aligns with the National Electrical Code (NEC) provisions, which stipulate that such connections are acceptable for securing conductors. Binding screws or studs provide a reliable and robust mechanical connection, ensuring that the conductors are held firmly in place and reducing the risk of disconnection due to vibration or movement.

In contrast, twist-on wire connectors, while common, are typically used for larger gauge conductors to ensure secure joins. Solder connections, although reliable, may not provide the mechanical strength needed for certain installations, especially if not done correctly. Welded connections, while they can provide a strong bond, are not commonly utilized for general conductor connections and require specific equipment and training. Therefore, binding screws or studs with unturned lugs stand out as the most appropriate and acceptable method for connecting #10 or smaller conductors, prioritizing both safety and code compliance.
