CONDUIT SIZE
Use these charts as a guideline to
determine the necessary conduit sizes for
the wiring of the GASBOY Islander.
When actually determining the size of a
conduit, you may need to increase conduit
size because of a long run or large number
of bends.
To determine conduit size needed, use the
THHN/THWN Wire Areas table (left) to
find the area for each wire gauge. Add up
all wire areas. Use the Areas of Trade
Size Conduit Table (right) to select the
smallest number in the 25% fill area
(based on NEC 501-1) that comes closest
without exceeding the total wire area.
