8 — ElectriCalc Pro
Ampacity Tables
The ElectriCalc Pro uses NEC Table
310-16 (310-17 for Free Air) to find wire
sizes and ampacity ratings of wires.
The calculator uses the following data
to calculate wire size: 1) insulation
temperature rating (60°C, 75°C and
90°C); 2) wire material (copper or
aluminum); and 3) ambient temperature.
Standard AWG wire sizes and Circular
Mils are used by the
ElectriCalc Pro.
Wire size entries less than or equal to
2000 are accepted as AWG wire sizes;
entries greater than 2000 are accepted
as Circular Mil entries and display the
corresponding AWG wire size. Entries
must match the standard wire sizes or
Circular Mils; otherwise, “nonE” will be
displayed (Invalid entry).
NOTE: 1/0, 2/0, 3/0 and 4/0 wires are
entered using the
0
key (e.g., 0, 00,
000 and 0000).
w
— Wire Size/Ampacity
Enters or calculates wire size based on
ampacity and Voltage drop, if a Voltage
drop length has been entered.
♦ 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. The calculator will use the larger
value when calculations require a wire
size. If no Voltage drop length has been
entered, the calculator will display the
calculated ampacity rated wire size.
