18 — ElectriCalc Pro
Conduit Sizing Keys
The ElectriCalc Pro calculates conduit
size using NEC Tables 1, 3, 4, and 5 of
Chapter 9 (given insulation type, wire
size, and quantity of wires). It will also
calculate the number of wires of a
specified insulation type and wire size
that will fit in a defined conduit size.
Acceptable conduit sizes (depending
on the type of conduit used) are as
follows: 1/2”, 3/4”, 1”, 1-1/4”, 1-1/2”, 2”,
2-1/2”, 3”, 3-1/2”, 4”, 5”, and 6”. Conduit
sizes are entered using decimal equiva-
lents (e.g., 1-1/2” is entered as 1.5, 3/4”
is entered as .75, etc.).

— Number of Wires
Used to enter or calculate the number
of wires in a raceway and calculate
cross-sectional wire area.
♦ First Press
Enters number of wires or calculates
maximum number of wires in conduit.
Displays: TTL WIRES (calculated) or
WIRES (entered).
♦ Second Press
Shows total cross-sectional area for all
entered wires. Displays: WIRE AREA
(entered) or TTL WIRE AREA (calculated).
♦ Third Press
Shows total cross-sectional area of all
entered wires of the selected wire insu-
lation. Displays: TTL WIRE AREA
