test methods used shall conform to the applicable NEMA Standards, and shall
be subject to the approval of the Contracting Officer. Reports of all
witnessed tests shall be signed by witnessing representatives of the
Contractor and Contracting Officer. The cost of performing all tests shall
be borne by the Contractor and shall be included in the prices bid in the
schedule for equipment.
2.10.1
Motor Control Centers Tests
2.10.1.1
Dielectric Tests
Each motor control center shall be completely assembled and given
dielectric tests in accordance with NEMA ICS 1.
2.10.1.2
The correctness of operation of each air circuit breaker [or motor circuit
protector] and magnetic contactor and of all control devices, accessories
and indicating lamps, shall be checked. These checks shall be made at
rated voltage with power supplies to the main buses. All magnetic
contactors shall also be checked for proper operation with power at 90
percent of rated voltage.
2.10.1.3
Short Circuit Tests
If the unit is not UL labeled for the specified short circuit, the
contractor may submit design tests demonstrating that satisfactory
short-circuit tests, as specified in NEMA ICS 2, have been made on a motor
control center of similar type of construction and having the same
available short circuit current at the motor terminals, including any motor
contributions, as the motor control centers specified to be furnished under
these specifications.
2.10.2
Switchboards Tests
2.10.2.1
Production Tests
Each switchboard shall be completely assembled and given applicable
production tests for assembled switchgear as specified in NEMA PB 2.
2.10.2.2
Short Circuit Tests
If the unit is not UL labeled for the specified short circuit, the
contractor may submit design tests demonstrating that satisfactory
short-circuit tests have been made on a switchboard of similar type of
construction and of the same short-circuit rating as the switchboards
specified to be furnished under these specifications.
2.10.3
Panelboards Tests
Each panelboard shall be assembled with cabinet and front to the extent
necessary to check the fit and provisions for installing all parts in the
field. Each panelboard shall be given a dielectric test in accordance with
NEMA PB 1. All circuit breakers shall be operated to check mechanical
adjustments. All doors and locks shall be checked for door clearances and
fits and the performance of lock and latches.
