Direct answer
Cooking unit, counter-mounted is a defined term in the International Residential Code (IRC) 2009, in Electrical Definitions. The code's own words are: “A cooking appliance designed for mounting in or on a counter and consisting of one or more heating elements, internal wiring and built-in or separately mountable controls.” 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 Power and Lighting Distribution (IRC 2009), Branch Circuit and Feeder Requirements (IRC 2009), Electrical Definitions (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 cooking unit, counter-mounted?
The International Residential Code (IRC) 2009 defines it in Electrical Definitions as: “A cooking appliance designed for mounting in or on a counter and consisting of one or more heating elements, internal wiring and built-in or separately mountable controls.” 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 cooking unit, counter-mounted?
In this corpus the term is used across 3 chapters, led by Power and Lighting Distribution 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 code for kitchen counter outlets?
Kitchen is a separate defined term. The IRC 2009 defines it as: “Kitchen shall mean an area used, or designated to be used, for the preparation of food.” That is not the same as cooking unit, counter-mounted, which the IRC 2009 defines as “A cooking appliance designed for mounting in or on a counter and consisting of one or more heating elements, internal wiring and built-in or separately mountable controls.” — read both before applying either, and confirm the wording in the edition your jurisdiction has adopted.
What is the branch circuit demand load for a 6 kW counter mounted cooking unit?
In the 2009 I-Codes hosted here it is a defined term rather than a description. The IRC 2009 states, in Electrical Definitions: “A cooking appliance designed for mounting in or on a counter and consisting of one or more heating elements, internal wiring and built-in or separately mountable controls.” It is defined in IRC 2009. It is not the same as Branch Circuit, which the IRC 2009 defines separately as “The circuit conductors between the final overcurrent device protecting the circuit and the outlet(s).” 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.
