A chassis ground symbol symbolizes a ground point.

A chassis ground symbol symbolizes a ground point.

• A. Not used in circuits
• B. Symbol used for shielding
• C. True
• D. False

Answer: (D)

Chassis grounding marks a connection to the equipment’s metal enclosure or shielding, not the circuit’s reference node. This symbol is used to show safety bonding or EMI shielding, and while the enclosure may be tied to earth in some designs, it isn’t guaranteed to be the circuit’s ground reference. Because a ground point in a schematic usually denotes the common reference for voltages in the circuit, the chassis ground symbol does not inherently represent that same ground point. So the statement is false; the chassis ground symbol indicates a chassis/shield connection rather than a general ground point.
