MAINTENANCE AND TESTING OF ELECTRICAL SYSTEMS
PART - GENERAL
DESCRIPTION OF WORK
Testing of electrical systems.
Submission of reports and tests.
PART - PRODUCTS
MATERIALS
Miscellaneous testing equipment as detailed.
PART - EXECUTION
INSTALLATION
Test the equipment and systems and demonstrate their proper operation to the Engineer.
1. Do not test equipment until it has been fully prepared, connected, and made ready for normal operation. Repair any equipment damaged by improper operation or testing at no cost to the Owner before final inspection and acceptance.
FEEDER TESTING
Megger all feeders. If insulation resistance on any circuit is less than 1 megohm, such circuits are to be considered defective and must be replaced. Submit test results for each phase of each feeder from the output report files of the tester. Document all readings and submit to the Engineer.
OVERALL ELECTRICAL SYSTEM
Conduct voltage tests at the time of energizing the distribution system in the presences of the Engineer and carry out such corrective measures as may be required.
B. Adjust all systems and leave in proper operating condition.
C. Test all wiring and leave free of defective installation and unintentional grounds.
D. Balancing Three Phase Loads.
1. Prior to turning the building over to the Owner, turn on all equipment in the building including lighting and with an amprobe, read the current drawn on each hot leg of the feeder supplying each distribution panel. If the current in any one leg varies more than 5% +/- from the arithmetic average of the current in all the hot legs, reconnect the branch circuits to obtain a balanced loading.
OCCUPANCY SENSOR TESTING
Upon completion of the installation phase, test and adjust each occupancy sensor to insure proper operation.
B. General rooms and offices: Set the time delay to OFF after 15 minutes of inactivity. Set the sensitivity of each device to trip the lights ON from anywhere in the room, but not so sensitive to trigger the lights on from motion outside the room.
C. Corridors and hallways: Set the time delay to OFF after 20 minutes of inactivity. Set the sensitivity of each device to trip the lights ON from anywhere in the corridor/hallway.
D. For dual technology sensors, set the sensor to maintain an ON condition if either technology is triggered from within the room after an initial ON. Set the device to initiate an ON condition only if both technologies sense motion from within the room.
E. Test all operational features of the system at this time.
F. Where required, make appropriate corrections and adjustments.
GROUND FAULT TESTING
Perform field primary injection testing of ground fault protection system.
B. Test ground fault protective devices immediately after installation. Submit settings and testing report to the Engineer.
C. Include a copy of the GF test report in the O&M manual.
