Wiring Precautions
The quality of the electrical installation is a major factor in maintaining proper safety levels
and providing trouble-free operation of your Gasboy pump. To assure a quality installation,
follow these rules:
• 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.
• Use only threaded, rigid, metal conduit.
• Use only UL-approved insulated gasoline and oil-resistant stranded copper wiring of the
proper size.
• Wire connections should be properly trimmed and secured with a wire nut; close off the
open end of the wire nut with electrical tape.
• The line to the motor should be on a separate circuit and installed on a 20 to 30 Amp
breaker depending on the motor size and/or the voltage setting and the wiring run.
• Install an emergency power cutoff. In addition to circuit breaker requirements of NFPA 70
and NFPA 30A, a single control which simultaneously removes Alternating Current (AC)
power from all site pumping equipment is recommended. This control must be readily
accessible, clearly labeled, and in accordance with all local codes.
The DISABLE PUMPS, and STOP buttons at the facility building and the optional
DISABLE PUMPS button on the Island Card Reader (ICR) WILL NOT shut off
electrical power to the pump.
This means that even if you activate these stops, fuel may continue to flow
uncontrolled.
You must use the TOTAL ELECTRICAL SHUT-OFF in case of an emergency and
not only these facility building and ICR station “stops”.
WARNING !
In order to provide the highest level of safety to you, your employees, and customers, it is
recommended that all employees be aware of the location and are trained on the procedure for
turning off power to the entire system.
