Racon Engineering Inc. - Voltage Drop

This Calculator will determine the minimum size conductor needed based on a 3% Voltage Drop. Divide the calculated distance by 3 and multiply by any other percentage voltage drop to obtain the allowable distance. This calculator does not account for allowable amperage for a conductor as per Tables 1,2,3, or 4. Consult the Canadian Electrical Code, Part I, latest edition and your local authority having jurisdiction for further details.
