CONDUIT REQUIREMENTS
General All wiring (AC and DC) connecting the different components of the Series 1000
System must be installed in threaded, rigid, metal conduit. PVC IS NOT
ACCEPTABLE. Components of the system include pumps, dispensers,
submersible pumps, submersible starter relays, Series 1000 System, and circuit
breaker panels. Communication equipment signal wires should also be run in
metal conduit, (except for RS-422 wiring as noted in Section 6,
Communications).
AC Power High voltage AC power wires must be installed in separate conduit from the
low voltage DC signal wires. The AC power wires and DC signal wires must
not be run in any sort of common conduit or trough (except for RS-422 wiring as
noted in Section 6, Communications).
Connections All conduits must be connected to the Series 1000 pedestal through the holes and
knockouts provided by the factory. Do not make any other holes in this unit. If you
must make holes at locations other than those provided, contact GASBOY for
approval first.
Conformity All wiring and conduit runs must also conform with the National Electrical Code
(NFPA 70), the Automotive and Marine Service Stations Code (NFPA 30A), and
State and Local Electrical Codes.
Size Use the Conduit chart (Figure 5-3) as a guideline for determining the necessary
conduit sizes for the wiring of the GASBOY Series 1000 System. When actually
determining the size of conduit, you may need to increase conduit size because of
a long run or large number of bends. Use the Wire Size chart (Figure 5-6) to
determine the gauge of wire that should be used in the installation. The installer
should determine the orientation of the wire runs according to the layout of the
components at the site and the applicable GASBOY wiring diagrams. This chart
is based on using metal thin wall conduit (THWN) with 50% fill of gas-and oil-
resistant wire.
Warranty The GASBOY warranty will not apply to any system in which AC and DC wires
are run in the same conduit, J-Box or wireway. The GASBOY warranty will not
apply to any system using PVC conduit.
