How to connect the grounding wire to the cable junction box
To ground a metal junction box, connect the circuit's bare copper or green insulated grounding wire to the box using a designated green grounding screw or a grounding clip. From there, extend a grounding pigtail to any electrical devices (outlets, switches) housed within the box. By following these procedures, you can ensure your electrical installations are safe, compliant with electrical codes, and provide a reliable grounding system that. When multiple cables enter a junction box, the bare equipment grounding conductors must be joined together to maintain the continuity of the circuit's protective path. This is typically achieved using a short conductor known as a “pigtail,” which connects the bundle of incoming wires to the. A ground junction box is an electrical enclosure specifically rated and constructed to house wire splices in conditions where they are exposed to moisture, dust, or physical damage. The basic rule achieves this through an equipment grounding jumper; four exceptions.
