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/dispenser. To assure a quality
installation, follow these rules:
1
All wiring is to be installed and used in accordance with local building/fire codes, all Federal,
State, and Local codes, the National Electrical Code (NFPA 70), NFPA 30, and the
Automotive and Marine Service Station Code (NFPA 30A) codes and regulations. Canadian
users must also comply with the Canadian Electrical Code.
2
Use approved conduit and insulated gasoline and oil resistant copper wiring of the proper size.
3
Wire connections must be tightly spliced and secured with a wire nut; close off the open end of
the wire nut with electrical tape.
4
Install an emergency power cutoff. In addition to circuit breaker requirements of NFPA 70,
NFPA 30, NFPA 30A and the Canadian Electrical Code (Canadian users only), 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 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.
To reduce the risk of electrical shock when servicing, turn off all power to the pump/dispenser.
In submersible pump applications, turn off all power to the submersible pump and any other
dispensers which use that submersible pump. AC power can feed back into a shut-off
dispenser when dispensers share a common submersible pump or starter relay.
WARNING
!
Pour réduire le risque de choc électrique lors de l'entretien/révision, coupez totalement le
courant à la pompe/distributeur. Dans les applications de pompe immersible, coupez
totalement le courant à la pompe immersible et tous autres distributeurs qui utilisent la pompe
immersible. Le courant alternatif peut alimenter de nouveau un distributeur à l'arrêt quand les
distributeurs partagent une pompe immersible commune ou un relais de démarrage.
