Which of the following does NOT conform to electrical grounding practices?

Connecting to an ungrounded body does not conform to electrical grounding practices because proper grounding requires a connection to the earth or a conductive body that is grounded. The purpose of grounding is to ensure safety by providing a path for electric current to dissipate in the event of a fault, thus preventing electrical shock or fire hazards. An ungrounded body lacks this safety feature, making it an inadequate choice for grounding.

In contrast, using a cable that is insulated is considered safe and compliant with grounding practices, as insulation helps prevent unintended contact with live electrical components. Creating a direct connection to the ground is a fundamental grounding practice, as it allows for the safe dissipation of electrical energy. Similarly, connecting to a conductive body that is properly grounded enhances safety by providing a low-resistance path to the ground.
