Before splicing or making a connection with a Type THHN conductor, what must be done?

Before splicing or making a connection with a Type THHN conductor, the conductor ends must be stripped and cleaned to ensure a reliable and secure electrical connection. Stripping the wire removes the insulation at the ends, exposing the conductive material that allows current to flow. Cleaning the ends is equally important as it removes any dirt, oxidation, or contaminants that might interfere with the connection, potentially causing increased resistance or even a failure in electrical continuity. Proper preparation of the conductor ends is essential for achieving a good splice or connection, ensuring safety and reliability in electrical circuits.
