Is it permitted to use a set-screw type pressure connector to complete the connection of conductors to terminal parts?

The use of a set-screw type pressure connector to complete the connection of conductors to terminal parts is indeed permitted according to the National Electrical Code (NEC) and Ohio Electrical Code requirements. These types of connectors are designed to securely hold conductors in place, ensuring a reliable and safe electrical connection.

Set-screw connectors provide a straightforward method for making connections, especially in situations where quick installation is desired. They are commonly used in various applications, noting that the pressure the set-screw applies is sufficient to maintain a continuous electrical connection under normal service conditions. The integrity of these connections is paramount in preventing overheating and maintaining safety standards within the electrical system.

The approval of set-screw type connectors recognizes their effectiveness in various installations, provided they are used in accordance with manufacturers’ guidelines and NEC standards. This allows for increased versatility and options for electricians and contractors in completing their work efficiently and safely.
