The ElectriCalc Pro can calculate the size
of conduit required when running single or
multiple wires using the C 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 fol-
lowing the guidelines in NEC Chapter 9,
Tables 1, 3, 4 and 5), the calculator can
calculate a conduit size based on the con-
duit type and the same or different wire
types and sizes.
To select a specific conduit type, enter
the corresponding number of the conduit
and then press S C. The numbers
and types are:
1) EMT 2) ENT 3) FMC 4) IMC
5) LFNB 6) LFNA 7) LFMC 8) RMC
9) P-80 10) P-40 11) P-A 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).
