Operator Positions often require a bonded SBB.

• A. True
• B. False
• C. Not sure
• D. Occasionally

Answer: (A)

Ensuring a solid electrical bonding at operator work areas is essential for safety and equipment protection. A bonded SBB provides a common bonding point that ties together the site’s metalwork—frames, enclosures, racks, cabinets—and the grounding system so all conductive parts share the same electrical potential. This prevents dangerous touch voltages when people interact with equipment and ensures fault currents have a reliable path to trip protective devices. Operator positions are where personnel are most exposed to potential differences, so the guidelines require that a bonded SBB be present there. That’s why the statement is true—the bonding at the operator location is a standard safety and protection measure, not optional.
