ABSTRACT
Recognizing electrical equipment is easy because we use so much of it. If we ask typical waterlwastewater maintenance operators where such equipment is located in their plant sites, they know, because they probably perform maintenance on the same devices or their ancillaries. If we asked these same maintenance operators what a particular electrical device does, they could probably tell us. If we were to ask if their plant electrical equipment was important to plant operations, the chorus would resound, "absolutely."
