Reference boundary

Rating-label reference only. It does not select transformer size, efficiency class, protection, conductor size, or available fault current.

Reference table

Reference common dry-type transformer kVA ratings and corresponding full-load current examples.

Reference basis uses common dry-type kVA labels with current examples from three-phase kVA conversion.
