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.
