2.8.4
Incoming Sections
Metal-enclosed compartments shall be provided for terminating the incoming
high-voltage power cables with stress cones as indicated. Access to the
interior of the compartment shall be through removable bolted panels or
bolted hinged doors. Connections between the terminals of the incoming
cables and the high-voltage winding terminals of the adjacent transformers
shall be by means of copper or aluminum bus with not less than [600]
[_____] amps. continuous current-carrying capacity and [_____] asymmetrical
amperes momentary current rating. Heavy-duty clamp type terminal lugs
shall be provided for connecting the high-voltage cables to the transformer
high-voltage bus.

FACTORY INSPECTION AND TESTS
2.9.1
General
Each item of equipment supplied under this contract shall be given the
manufacturer's routine factory tests and also other tests, as specified
below, to insure successful operation of all parts of the assemblies. All
tests required shall be witnessed by the Contracting Officer, unless waived
in writing, and no equipment shall be shipped until it has been approved
for shipment. The Contractor shall notify the Contracting Officer
sufficiently in advance of the test date, so that the Contracting Officer
can make arrangements to be present. The factory test equipment and test
methods used shall conform to the applicable requirements of ANSI, IEEE and
NEMA standards, and shall be subject to approval. The witnessing
representatives of the Contractor and the Contracting Officer shall sign
all test reports.
2.9.2
Switchgear Assembly Tests
Each low-voltage air circuit breaker switchgear assembly shall be subjected
to the [_____] ["Production Tests"] described in [IEEE C37.20.1][IEEE
C37.20.2][IEEE C37.20.3], except as modified or supplemented below:
2.9.2.1
Assembled Equipment
The assembled equipment shall be checked for mechanical adjustment,
alignment of panels and devices mounted thereon, adequacy of fastenings and
general good workmanship.
2.9.2.2
Wiring
Control, instrument and relay wiring shall be given a point-to-point check,
and the correctness of the control wiring shall be verified by actual
operation of the compartment devices.
2.9.2.3
Switchgear Assembly
Each switchgear assembly, with all circuit breakers in operating position
and contacts closed, shall be subjected to a 1-minute power frequency
withstand dielectric test of 2,200 volts AC. Control, instrument and relay
wiring shall be subjected to a 1-minute, power frequency withstand
dielectric test of 1,500 volts AC to ground.
2.9.2.4
Circuit Breaker
Each low-voltage power circuit breaker shall be given the production tests
