Electrical Calculator - Freeware

Makes Electrical Calculation a Piece of Cake

Selecting overload protection and wires for transformers involves number of rules that change with transformer size, type, and placement of the overload protection. This calculator helps determine the current values on both sides of the transformer, and estimates available short circuit current. Download.
