What is generally not permitted as a method for identifying the receptacle equipment grounding conductor connection point if it's not visible?

The identification of the grounding conductor connection point is critical for ensuring electrical safety and compliance with regulations. In contexts where the equipment grounding conductor connection point is not visible, clear and standardized methods for identification are necessary.

The method that is generally not permitted is to use the term "Equipment Ground." This term is somewhat generic and can be confused with various components and connections throughout electrical systems. A more specific and clear designation is needed to effectively communicate the connection point, as ambiguity could lead to improper maintenance or misunderstandings regarding electrical safety.

In contrast, the other options—such as the word "Grounding," a green dot marker, or an arrow pointing to the ground—are more visual and direct methods of identification. "Grounding" is a widely recognized term, a green dot marker is specifically used to denote grounding connections consistently, and an arrow pointing to the ground provides a clear direction indicating where the connection is located. Such indicators help ensure that anyone working near the equipment can quickly and easily recognize the grounding point, enhancing safety and compliance with installation requirements.
