ELECTRICAL SYSTEM
A. Electrical branch circuits from panel board and feeder from main distribution panel shall be
provided by Div 16. Panel to be equipped with means of disconnecting all fueling system
circuits per NFPA 70.
B. All required field control wiring and conduit for the fuel system shall be provided by the
equipment supplier to ensure a complete and coordinated system and maintain a single
source of responsibility. All field control wiring shall be labeled in conjunction with system
devices and shall be verified has required to ensure all devices and equipment are properly
terminated.
C. Tank shall be grounded by Div. 16.
3.04
TESTING
A. Pneumatically test tanks in accordance with manufacturer's recommendations upon arrival at
the Project Site and after tank installation to assure tank integrity.
B. Primary (Product) Piping Test: Hydrostatically test system at 100 psi and carefully check for
leaks. Repair all leaks and retest until proven watertight. Flush system thoroughly with diesel
fuel until all moisture or debris is removed and diesel is clear. Fill system with clean diesel
fuel, close end valves and allow system to remain full. Legally dispose of flush diesel.
C. Secondary Containment Piping Test: Seal secondary containment piping to primary piping at
both ends with concentric termination fittings as recommended by the manufacturer. Provide
test gauge and pipe connection at this point for pneumatic testing. Pneumatically test system
at 10 psi for ten (10) minutes, then soap all joints and check for leaks. Retest until there are
no leaks and system is proven tight.
3.05
FUNCTIONAL TESTING
A. Before witness testing and/or commissioning the system perform these steps to ensure the
system is ready for final acceptance test as required:
1. Ensure all devices are in place and operational.
2. Ensure all controls are operational.
3. Move fuel through system filling and returning to/from day tanks to verify control
sequences.
4. Clean all strainers.
