Wiring Precautions
Note: Customers and installers having any questions pertaining to the installation should
contact their Gasboy distributor.
The quality of the electrical installation is a major factor in maintaining proper safety levels
and providing trouble-free operation of your pump. To assure a quality installation, follow
these rules:
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 Use only threaded, rigid, metal conduit.
3 Use only UL-approved insulated gasoline and oil-resistant stranded copper wiring of the
proper size.
4 Wire connections should be tightly spliced and secured with a wire nut; close off the open end
of the wire nut with electrical tape.
5 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.
6 Install an emergency power cutoff. In addition to circuit breaker requirements of NFPA 70 and
NFPA 30A, a single control which simultaneously removes AC power from all site dispensing
equipment is recommended. This control must be readily accessible, clearly labeled, and in
accordance with all local codes.
To reduce the risk of electrical shock when servicing, turn off and lock out all power to the
pump, including the motor.
WARNING
7 Qualified electricians who are familiar with installation of this type of equipment must
perform the installation of the pump.
