CONDuIT SIZE
The
ElectriCalc Pro
can calculate the size of Conduit required
when running single or multiple Wires using the
key and the
calculator’s internal tables. The calculator uses NEC values for area
of THW/THHW, XHH/XHHW, and THHN/THWN wires. When using
the actual Wire areas (and following the guidelines in NEC Chapter
9, Tables 1, 4 and 5), the calculator can calculate a Conduit Size
based on the Conduit Type and the same or different Wire Types
and Sizes.
To select a specific Conduit Type, enter the corresponding number
of the Conduit as shown below and then press
.
The types and their corresponding numbers are:
1) eMT
4) IMC
7) lfMC
10) P-40
2) enT
5) lfnb
8) RMC
11) P-a
3) fMC
6) lfna
9) P-80
12) P-eb
When you enter a new Conduit Type or scroll through the types,
you will see the updated Conduit Size (if you have entered the
Wire Type and quantity).
