Conduit Layout System Layout
All wiring and conduit runs must conform with all building/fire codes, all Federal, State, and
Local codes, the National Electrical Code (NFPA 70), NFPA30, and the Automotive and
Marine Service Stations Code (NFPA 30A). Canadian users must also comply with the
Canadian Electrical Code.
Use the charts in Figure 3-4 as a guideline to determine the proper conduit sizes for the
Gasboy Series 1000 fuel management system. When planning the orientation of the wiring
runs, follow the applicable Gasboy wiring diagram and consider the layout of the components
at the site. Long runs or a large number of bends may require you to increase conduit size over
what is listed.
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.
