CONDUIT REQUIREMENTS
The conduit requirements outlined in this section are relevant to all components making up the
GASBOY system. The GASBOY Warranty will not apply to any system deviating from the
requirements outlined in this section.
All wiring and conduit runs must conform with all building/fire codes, all Federal, State, and Local
codes, National Electrical Code (NFPA 70), NFPA 30, and Automotive and Marine Service Station
Code (NFPA 30A) codes and regulations. Canadian users must also comply with the Canadian
Electrical Code.
All wiring (AC and DC) connecting the different components of the Fuel Point System and all
communication equipment signal wires must be installed underground in threaded, rigid, metal
conduit. PVC IS NOT ACCEPTABLE. High voltage AC power wires must be installed in
separate conduit from the low voltage DC signal wires; they cannot be run in any sort of common
conduit or trough. Exceptions to these requirements are noted in Section 3, Communication
Requirements (RS-485). I/S wires must be in separate conduit from all AC or DC wires.
All holes and knockouts accept up to 3/4" conduit. All conduit must be connected to the
components through the holes and knockouts provided by the factory. Do not make any other
holes in these units. If alternate holes are required, contact GASBOY for approval first.
The chart below shows conduit capacity for rigid metal conduit with 50% fill of gas- and oil-
resistant wire. Use this chart as a guideline to determine the proper conduit sizes for the
GASBOY Fuel Point System wiring. When planning the orientation of the wire runs, follow the
applicable GASBOY wiring diagrams 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.
