Voltage Drop Calculator

This tool helps you calculate the voltage drop, percentage voltage drop, and voltage at the end of a wire run based on input parameters such as wire type, size, phase, distance, and load.

Wire Material

Select the type of conductor material.

Wire Size

Select the wire gauge or kcmil.

Material of Conduit

Select the conduit type.

Power Factor (PF)

Enter the power factor (e.g. 0.9)

Voltage (V)

Enter the system voltage.

Phase

Select the type of electrical system.

Number of Conductors

Select how many conductors are in parallel per phase.

Distance (one-way)

Enter the one-way distance of the wire run.

Load Current (Amps)

Enter the current flowing through the wire.
