ARTICLE 440. AIR-CONDITIONING AND REFRIGERATING EQUIPMENT440.2. Definitions. The first definition for "Branch-Circuit Selection Current" is extremely important because of the differences between it and the last definition, covering "rated-load current." The latter corresponds to full-load current in many other places. The former includes the effects of the degree of sustained overload that the unit is capable of under defined test conditions. It always at least equals, and usually exceeds the rated-load current. The definition is critical because, where given, it becomes the number upon which the other size or ratings of elements of the circuit are determined, including conductors, overcurrent protective devices, and disconn…
