Terminology Although much of the electrician's field terminology matches that of the electrical codes, usages can vary Neutral wire is the return conductor of a circuit;. It is best to obtain the actual load and noload losses in watts from the transformer manufacturer, but sometimes those data are not available In that case, temperature rise is a rough indicator of transformer efficiency For example, a transformer with an 80C temperature rise uses 1321% less operating energy than a 150C rise unit.
