ABSTRACT
Ampacity is the term that was conceived by William Del Mar in the early 1950s when he became weary of saying "current carrying capacity" too many times. AIEE/IPCEA published the term "ampacity" in 1962 in the "Black Books" of Power Cable Ampacities [13-1]. The term is defined as the maximum amount of current a cable can carry under the prevailing conditions of use without sustaining immediate or progressive deterioration. The prevailing conditions of use include environmental and time considerations.
