Direct answer
Grounding electrode is a defined term in the International Residential Code (IRC) 2009, in Electrical Definitions. The code's own words are: “A conducting object through which a direct connection to earth is established.” No other I-Code in this corpus defines it, so the IRC 2009 definition is the one to work from. The term is used in 3 chapters of this corpus, most often in Services (IRC 2009), Electrical Definitions (IRC 2009), Fuel Gas (IRC 2009). These pages transcribe the 2009 model text; verify the definition against the edition and amendments your authority having jurisdiction has adopted. Record the jurisdiction, the adopted edition, the application date and any local amendment that rewrites the definition before you use it on a live project, because a term redefined by amendment changes every requirement that depends on it.

Frequently asked questions
What is the code definition of grounding electrode?
The International Residential Code (IRC) 2009 defines it in Electrical Definitions as: “A conducting object through which a direct connection to earth is established.” The 2009 model text is reproduced here; the definition that binds your project is the one in the edition your jurisdiction has adopted, as amended locally.
Which parts of the code depend on grounding electrode?
In this corpus the term is used across 3 chapters, led by Services in the IRC 2009. Those are the sections whose scope moves if the definition is amended locally, so read them together with Chapter 2 rather than on their own.
What is the definition of a grounding electrode?
In the 2009 I-Codes hosted here it is a defined term rather than a description. The IRC 2009 states, in Electrical Definitions: “A conducting object through which a direct connection to earth is established.” It is defined in IRC 2009. Because it is a defined term, whatever the adopted edition says it means is what every section using it means — so check Chapter 2 of that edition and any local amendment before relying on this wording.
