What is true regarding multiple equipment grounding conductors entering an outlet box?

When multiple equipment grounding conductors enter an outlet box, it is essential that they must first be connected using an approved method. This is crucial for ensuring proper grounding and maintaining a safe electrical system. An approved method typically involves the use of ground bar or terminal that is designed to securely connect multiple conductors and ensure continuity of the grounding system.

Connecting all grounding conductors in this way helps to prevent ground loops, facilitates reliable grounding for all equipment, and promotes the overall safety of the electrical installation. Utilizing an appropriate method for connecting these conductors also complies with electrical codes and standards, which are in place to protect both people and property from electrical hazards.

Options that suggest leaving the conductors unconnected or connecting them directly to the neutral do not align with safety practices or code requirements. The suggestion that only one conductor should ever enter an outlet box ignores practical applications where multiple ground conductors are necessary for the grounding of various devices within that box. Thus, connecting multiple equipment grounding conductors using an approved method is the most comprehensive and safe practice.
