(4) weeks prior to scheduled field testing of the complete standby power systems.
3. Field NETA testing of the on-board engine genera tor circuit breaker shall be performed by the District’s installation Contractor. Any deficiencies found during this testing shall be corrected by the supplier at no additional cost to the District. All costs associated with subsequent field NETA testing that shall be required due to circuit breaker repair or replacement shall be the responsibility of the Supplier.
4. All travel and subsistence costs for supplier’s field technician site visits shall be included in the supplier’s quotation. If field testing is unsuccessful due to issues related to the supplier’s equipment then the supplier shall be responsible for all costs related to subsequent site visits that may be required until successful field testing, start-up and commissioning is completed.
5. The District’s installation Contractor shall def er main power connections from the supplied standby generator to the respective lift station power system to permit the supplier’s connection of a temporary, portable load bank for start-up and field testing purposes if required by the Supplier. The supplier shall be responsible for procuring any required temporary load bank equipment to the project site, providing all required temporary connection cables and connecting/disconnecting the temporary load bank to the generator equipment.
Supplier shall provide certification to the District, in writing, that new standby power system equipment is ready for connection by the District’s installation Contractor to the lift station facility power distribution system to facilitate Supplier’s final system commissioning.
6. Initial start-up and operation of the standby po wer system shall be performed by the supplier’s field technician with assistance from the District’s installation Contractor.
7. District shall notify the supplier of the propos ed field testing and commissioning date(s) four (4) weeks in advance of the proposed date(s) of equipment testing for each of the seven (7) lift station sites.
8. Supplier’s field technician shall inspect each c ompleted standby power system installation to confirm that the installation is correct and that the system is ready for start-up and commissioning.
9. Verification that each subsystem is complete and functions according to design criteria; include measurements of temperatures, pressures, and flows for all components.
10. Individual testing of each protective device an d verification of the accuracy of instrumentation set points.
11. With the generator either temporarily connected to the Supplier-furnished temporary, portable load bank system or connected to the lift station power system, the supplier’s field technician shall perform initial operation of the standby power system to verify stable operation, fuel consumption (measure fuel consumption approximately by measuring supply tank drawdown), engine
