Which of the following is NOT considered a defect found in an electrical panel?

A wire splice is a common practice in electrical systems and is not inherently considered a defect as long as it is executed properly. This means that the splices should be made using appropriate connectors, should be insulated adequately, and should comply with the local electrical codes. Well-installed wire splices can allow for the safe joining of wires, which is often necessary in electrical installations.

In contrast, a lack of a legend can hinder the understanding of the panel’s circuits, rusted enclosures can compromise the integrity and safety of the electrical equipment, and missing knockouts can create potential points of entry for moisture or unauthorized access, all of which are recognized defects that may lead to safety concerns.
