Voltage Drop Calculator - NEC Applications

This voltage drop calculator is applicable only to NEC applications. It does not optimize conductor sizes for several different loads at various points in a circuit. The total combined load and length of the circuit must be used. Consult with an engineer if your application does not fit into one of the following categories and/or requires more complex engineering calculations.
