CONDUIT LAYOUT
CONDUIT SIZE CHART
Use these charts as a guideline to determine the
necessary conduit sizes for the wiring of the
GASBOY Series 1000 System. 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.
