Which condition indicates a system that is not grounded?

• A. High impedance readings
• B. Direct connection to earth
• C. No intentional connection between conductors and earth
• D. Intermittent electrical flow

Answer: (C)

A system that is not grounded is characterized by the absence of an intentional connection between the electrical conductors and the earth. Grounding is a crucial safety measure that helps to mitigate the risk of electric shock, protect equipment, and provide a reference point for the electrical system. When there is no intentional connection to the earth, the system lacks this safety feature, leaving it vulnerable to faults that could lead to dangerous conditions. High impedance readings can occur in various situations, including when the system is functioning correctly but not grounded. A direct connection to the earth typically indicates that a system is grounded, and intermittent electrical flow may suggest issues with power supply or components rather than grounding status. The key factor in recognizing an ungrounded system is the absence of that intentional connection to the earth, which is essential for proper grounding.
