Grounding is:

  • A.Connection of current carrying parts to ground
  • B.Connection of non-current carrying parts to ground
  • C.Connection of any body to ground which is non current carrying
  • D.Interconnection of earthing pits

Answer: A

Grounding is the Connection of current carrying parts to ground.

In the usage this question follows, grounding means connecting a current-carrying part of the system, typically the neutral of a generator or transformer, to earth. It stabilises the system voltage with respect to earth and lets earth fault protection operate.

Connecting non-current-carrying metal parts such as equipment frames and enclosures to earth is called earthing, which protects people from shock. Interconnecting earth pits is part of building an earthing system, not the definition of grounding.
