Which statement relating to electric wiring is true?

• A. When attaching a terminal to the end of an electric cable, it should be determined that the strength of the cable-to-terminal joint is at least equal to the tensile strength of the cable itself.
• B. Electric wiring does not need to be tested before installation.
• C. It is acceptable for cable terminals to exceed the tensile strength of the cable.
• D. Cable should never be attached to any terminal.

Answer: (A)

The statement that when attaching a terminal to the end of an electric cable, it should be determined that the strength of the cable-to-terminal joint is at least equal to the tensile strength of the cable itself, is accurate because it emphasizes the importance of a secure connection in electrical systems. Ensuring that the joint can withstand at least as much force as the cable itself prevents failures that may lead to electrical faults, short circuits, or even physical damage to the wiring. Connections that are weaker than the cable can lead to failures under stress, such as pulling or bending of the wire, which could result in loose connections or breaks. This careful consideration helps maintain the integrity and safety of the electrical system, ensuring reliability and longevity in its performance. By ensuring a robust and equally strong connection, electrical engineers uphold safety standards and reduce the risk of hazards associated with electrical systems.
