Ground or Grounding

Connecting electrical components to earth for safety.

 

Electrical circuits may be connected to ground (earth) for several reasons. In powered equipment, exposed metal parts are connected to ground to prevent contact with a dangerous voltage if electrical insulation fails. Connections to ground limit the build-up of static electricity when handling flammable products or when repairing electronic devices. In some power transmission circuits, the earth itself can be used as one conductor of the circuit, saving the cost of installing a separate return conductor.
