What term describes the system that safely routes unwanted current to the earth to protect workers?

• A. Grounding
• B. Bonding
• C. Insulation
• D. Isolation

Answer: (A)

Grounding is the system that safely routes unwanted current to the earth, creating a low-impedance path that carries fault current away so protective devices can trip quickly. This keeps exposed metal parts at earth potential and reduces the risk of electric shock to workers. Bonding also helps by tying conductive parts together to prevent dangerous voltage differences, but it’s separate from the fault path to earth. Insulation and isolation block or separate current flow rather than providing a path for fault current to ground.
