What is a conductor used to connect equipment to a grounding electrode known as?

The correct term for a conductor that connects equipment to a grounding electrode is the Grounding Electrode Conductor. This type of conductor is specifically intended to establish a connection between the grounding electrode, which is typically a rod, plate, or other means of grounding, and the grounding system of the electrical installation.

In this context, it's essential to note that a Grounding Conductor generally refers to any conductor used to connect equipment or systems to a grounding system but does not specifically imply the connection to a grounding electrode. The Equipment Grounding Conductor, on the other hand, is used to connect the non-current-carrying metal parts of equipment to the grounding system, but again, it does not specifically point to the grounding electrode. Lastly, a Grounded Conductor refers to a current-carrying conductor that is intentionally grounded and does not apply in this situation, as it does not connect directly to a grounding electrode.

Thus, the specificity of the term Grounding Electrode Conductor makes it the correct choice in this context as it accurately describes the function of connecting equipment to the grounding electrode.
