finding Conduit size —
Multiple conductors, Different Wire Sizes and types
Three 1/0 THWN 75°C conductors and one #2 XHHW 75°C Copper
conductor are to connect to a panel board using a single Conduit.
What is the cross-sectional area of Wires, Conduit Size and actual
fill Area?
Note: The cross-sectional Areas are the same for both THHN and
THWN; display will show as THHN.
