Conduit Sizing Keys
The ElectriCalc Pro calculates Conduit Size using NEC Tables 1, 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 specied
Insulation Type and Wire Size that will t in a dened 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 equivalents (e.g.,
1-1/2" is entered as 1.5, 3/4" is entered as 0.75, etc.).
