Cable Testing is the process of evaluating the performance and integrity of electrical cables. This testing ensures that cables can transmit data or power effectively without any faults. Common tests include checking for continuity, insulation resistance, and signal quality. Various tools and equipment, such as cable testers and multimeters, are used during the testing process. These devices help identify issues like short circuits, breaks, or interference. Regular cable testing is essential for maintaining reliable electrical systems and preventing potential failures in both residential and commercial settings.
