What is a common method for terminating and splicing copper wire?

Pre-insulated copper terminal lugs and splices are a common method for terminating and splicing copper wire due to their effectiveness in providing a secure and reliable electrical connection. These lugs and splices come with an insulation material that helps protect against moisture and corrosion, which could lead to degradation of the connection over time.

Additionally, they are designed to be easy to install, often requiring simple tools to crimp the lug onto the wire, ensuring a strong mechanical and electrical bond. This is crucial in applications where wire integrity is paramount for safety and performance. The pre-insulated nature also simplifies installation, as the installer does not need to apply separate insulation after making the connection, streamlining the process.

Other methods, while valuable in specific situations, do not offer the same combination of reliability, ease of use, and protective quality as pre-insulated lugs and splices.
