What is the purpose of non-contact voltage detectors in relation to insulating rubber gloves or hot sticks?

The primary purpose of non-contact voltage detectors is to verify the presence of voltage in conductors. These devices enable personnel to safely assess whether electrical equipment or conductors are energized without needing to make physical contact. This is critical when working with or around live electrical systems, as it allows workers to ensure they are not approaching energized lines or components, thereby enhancing workplace safety.

Using non-contact voltage detectors alongside insulated rubber gloves or hot sticks enhances safety practices. While these gloves and sticks provide direct electrical insulation, the voltage detectors offer an additional layer of protection by allowing workers to identify live conditions from a distance before reaching in.

The other choices do not accurately reflect this purpose. They might refer to aspects related to the gloves' maintenance and condition but do not capture the specific function of non-contact voltage detectors. Therefore, confirming the presence of voltage in conductors directly aligns with the intended use of these testing instruments in electrical safety protocols.
