What is a common risk associated with improper wire termination?

Improper wire termination can lead to a range of issues, and one of the most significant risks is electrical shock. This danger arises when wires are not securely connected, which can expose conductive parts and increase the likelihood of unintended contact with live electrical components. If a person accidentally touches a poorly terminated wire, they may complete the electrical circuit, resulting in a shock that could vary in severity based on the voltage and current levels present.

The other options represent complications that can emerge from improper wire termination, such as voltage drop leading to poor performance, device malfunctions as a result of inconsistent connections, or potential data loss in cases where data lines are affected. However, electrical shock represents a direct and immediate danger to individuals working with or near the improperly terminated wires, making it a critical risk that must be addressed in both training and practice to ensure safety.
