For the purpose of these requirements, a busway is considered to be a grounded metal enclosure containing factory mounted conductors that are usually copper or aluminum bars, rods, or tubes. 

Values stated without parentheses are the requirement. Values in parentheses are explanatory or approximate information. 

Unless otherwise indicated, all voltage and current values mentioned in this Standard are root-mean-square (rms).
