Which of the following terms indicates a product's ability to prevent electrical shock hazards?

The term that indicates a product's ability to prevent electrical shock hazards is double insulation. This concept refers to the safety measure where an electrical device has two layers of insulating material separating the live components from the user. As a result, even if one layer of insulation fails, the second layer continues to provide protection, significantly reducing the risk of electrical shock.

In devices designed with double insulation, the construction ensures that it is intrinsically safer for consumers to use, particularly in environments where moisture or other risk factors may be present. Thus, double insulation effectively provides a reliable means of preventing electrical shock.

The other options, while related to electrical safety in some capacity, do not directly indicate the same level of protection against shock hazards as double insulation does. Low leakage refers to the minimal electric current that can leak from a device, contributing to safety but not as comprehensively as double insulation. Conduction safety may imply safe electric conduction but does not directly address shock prevention in the same way. Short circuit protection refers to mechanisms built into devices to prevent damage from excessive current, which is also important but distinct from protecting against electrical shock hazards.
