WIRING
Customers & installers having any questions pertaining to the installation should contact
their GASBOY distributor.
WIRING PRECAUTIONS
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.
In order to provide the highest level of safety to you, your employees, and customers, we
recommend that all employees be trained as to the location and procedure for turning off
power to the entire system.
WARNING:
To reduce the risk of electrical shock when servicing, turn off and lock out
all power to the pump.
7.
Have the pump installed by a competent installer/electrician.
GROUNDING
To ensure proper operation of the equipment and provide the necessary safety factors, this unit
must be grounded. A ground wire (preferably green) must be connected between the unit's AC
junction box ground lug and the main electrical service panel. One (1) earth ground connection is
required per unit. The ground rod is to be a solid, corrosion-resistant conductor and must be
installed at the main electrical panel in accordance with the National Electrical Code. It should be
properly tied into the ground bus strip of the panel. We recommend the neutral and ground bus
strips be bonded together (unless prohibited by local codes).
