Quick Voltage Drop Calculator

Mineral Insulated Copper-Sheathed Wiring Voltage Drop Calculator

The Quick Voltage Drop Calculator lets you calculate the voltage drop in a circuit based on ampacity, cable size, and circuit length for the nVent PYROTENAX MI copper-sheathed high-temperature wire and cable.
The calculated voltage drop represents line to line voltage drop in a 3-phase system under normal conditions, and includes an optional calculation of additional voltage drop in a fire zone under fire conditions.
No more tedious manual calculations; simply pick an MI high-temperature wire and cable based on the breaker size and check voltage drop with a few simple entries. If the voltage drop is too great, select the wire cable size that meets your specification.
