CONDUIT
All wiring to the GASBOY Electric Keytrol must be installed in threaded, rigid, metal conduit. PVC
is not acceptable.
All wiring and conduit runs must also conform with the National Electrical Code (NFPA 70) and the
Automotive and Marine Service Station Code (NFPA 30A). All wiring and conduit runs must
conform to local codes. Canadian users must also comply with the Canadian Electrical Code.
Use the charts below as a guideline to determine the proper conduit sizes for a remotely mounted
GASBOY Electric Keytrol. When planning the orientation of the wiring runs, follow the applicable
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.
WIRING DIAGRAMS
The following schematics show the standard wiring configuration for a GASBOY Electric Keytrol to
a typical dispenser. When connected to a GASBOY Series 9100A pump or dispenser, consult the
appropriate numbered wiring diagram immediately following these standard diagrams. If
connecting to a GASBOY Series 9800A, call GASBOY’s Quick Facts hotline for the appropriate
wiring diagram for your model pump or dispenser. If connecting to an older 9100, 115VAC, order
packet 024207 for the appropriate wiring diagram; for 230VAC applications contact Gasboy
Technical Service.
1. All wiring must be installed to 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.
2. Refer to the Wire Size section of this manual to determine the required line sizes.
3. Submersible starter relays are always recommended when a submersible pump is used;
however, the control circuit is capable or directly driving a submersible pump up to 3/4 HP at
115/230VAC. Any pump over 3/4 HP requires a submersible starter relay.
