Voltage Drop CalculatorDesigned to give the approximate loss factors in a circuit (AC or DC), including type of circuit, AWG or KCMIL, amperage, length of circuit and type of conductor, for wire. Enter the required data and click "Calculate". All results are estimates. In order to comply with national and local code, contact a qualified professional in your area. |
Conduit Fill CalculatorDesigned to give the approximate Minimum Raceway size based on a 40% maximum conduit fill. If Minimum Raceway reads "Exceeds Trade Size", the selected wiring and quanitiy has exceeded the 40% conduit fill of the largest conduit available, per the National Electrical Code®. Enter the required data (AWG or kcmil and Quantity) and click "Calculate". All results are estimates. In order to comply with national and local code, contact a qualified professional in your area. |
