First Press
If a wire length has been entered, the
first press will show the larger of the
ampacity or voltage drop derived wire

size. If no voltage drop length has been
entered, the calculator will display the
calculated ampacity rated wire size.
♦
Second Press
If a wire length has been entered, the
second press displays the smaller of
the two wire sizes. If not solving for
voltage drop wire size, then displays
