A metallic connection with the earth to establish ground potential is called what?

A metallic connection with the earth to establish ground potential is called what?

• A. Neutral
• B. Insulation
• C. Ground
• D. Bond

Answer: (C)

Grounding is the practice of creating a metallic connection to the earth to set a known reference potential and provide a low-impedance path for fault current. This establishes ground potential and helps protective devices trip quickly to protect people and equipment. The term described is ground. Neutral is the current-carrying return path and may be bonded to earth at specific points; insulation is non-conductive material; bonding links conductive parts to prevent dangerous voltage differences, often tied into the grounding system, but the act of connecting to earth to establish the reference is ground.
