3.4 MOTOR CONTROL CENTER TESTS

3.4.1 Factory Test Procedure

Rockwell Automation to perform all standard factory tests.

3.4.2 Factory Test Reports

Rockwell Automation to provide all factory test reports.

3.5 FIELD TESTING

Motor-control centers shall be subjected to continuity and insulation tests after the installation has been completed and before the motor-control center is energized.

Contractor shall provide test equipment, labor, and personnel to perform the tests required in the field. Conduct continuity tests using a dc device with bell or buzzer.

Motor-control centers shall be completely isolated from extraneous electrical connections. Substation feeder breakers, circuit breakers in switchboards, and other disconnecting devices shall be used to isolate the motor-control center under test.

Conduct insulation tests on 600-volt motor-control centers using a 1,000-volt insulation-resistance test set. Record readings every 15 seconds for the first minute and every minute thereafter for 10 minutes.

Resistance between phase conductors and between phase conductors and ground shall be not less than 50 megohms.

Conduct insulation tests on motor-control centers 480 volts or less using a 500-volt insulation-resistance test set. Record readings every 15 seconds for the first minute and every minute thereafter for 10 minutes.

Resistance between phase conductors and between phase conductors and ground shall be not less than 25 megohms.

Prior to final acceptance the motor control center shall be energized and loaded (to the maximum load possible, but not less than 10 percent of expected full load)for a minimum of 10 minutes and the temperature measured, with a non-contact device, to verify connection integrity. The temperature detector shall be accurate within 0.5 degrees C. Each phase temperature of 3 phase circuits and individual connections compared to other similarly loaded connections shall be within 3 degrees C of each other. Temperatures outside these values warrant investigation.

Conduct phase-rotation tests on all three-phase circuits using a phase-rotation indicating instrument. Phase rotation of electrical connections to motors and other connected equipment shall be clockwise.

Record test data and include location and identification of motor-control centers and megohm readings versus time.

Final acceptance shall depend upon the satisfactory performance of the motor-control centers under test. No motor-control center shall be energized until recorded test data have been approved by the Contracting Officer. Provide final test reports to the Contracting Officer. Reports

SECTION 26 24 19.00 26 Page 7 shall have a cover letter/sheet clearly marked with the System name, Date, and the words "Final Test Reports - Forward to the Systems Engineer/Condition Monitoring Office/Predictive Testing Group for inclusion in the Maintenance Database."
