Ground wires are spliced together and attached with a pigtail to the box and receptacle. The grounding wire nut shown has a hole in its top that makes installing a pigtail . See moreWhere plastic boxes are used, a ground wire typically connects to the receptacle only. Here, where wiring runs through this box to another box, a grounding pigtail connects to the device. See moreMany older ceiling fixtures are not grounded. Recent codes, however, call for grounding electrical wires in fixtures. To do so, connect the fixture's ground lead (usually a stranded wire) to the . See moreMost older switches are not grounded; many switches do not even have a ground screw. However, recent codes call for switches to be grounded. Replace an older switch with a newer one that has a ground screw and connect it to a ground wire. See more
