What is a key step in proper grounding and bonding of electrical equipment?

• A. Confirm proper connections to earth ground, bond equipment frames and enclosures to reduce touch potentials, and test continuity.
• B. Visual inspection is sufficient, no testing.
• C. Only check color codes on wires.
• D. Rely on the manufacturer's label alone.

Answer: (A)

Grounding and bonding create a safe, low-impedance path for fault current and keep exposed metal at the same potential to reduce shock risk. A key step is to confirm proper connections to earth ground, bond equipment frames and enclosures to that ground, and verify continuity of the bonding path. This ensures that if a fault occurs, fault current has a clear path to earth so protective devices can trip quickly, and it minimizes touch potentials on metal surfaces that someone could touch.

Relying on visual inspection alone doesn’t prove a solid ground or bond; miswraps, corrosion, loose connections, or breaks can exist even if everything looks fine. Color codes or labels by themselves don’t guarantee a correct or intact grounding path, and a manufacturer's label doesn’t reflect field conditions or verify actual continuity. The real check is confirming the physical, low-resistance connection to earth and testing the bonding path to confirm continuity.
