SECTION 3: RECEIVING, HANDLING, AND
STORAGE
Ground and Test (G&T) devices are subjected to complete factory
production tests and inspection before being packed. They are
shipped in packages designed to provide maximum protection to
the equipment during shipment and storage and at the same time
to provide convenient handling. Accessories such as the grounding
cables are shipped with the Ground and Test Device.
3.1 RECEIVING
Until the Ground and Test Device is ready to be delivered to the
switchgear site for installation, DO NOT remove it from the shipping
crate. If the Ground and Test Device is to be placed in storage,
maximum protection can be obtained by keeping it in its crate.
Upon receipt of the equipment, inspect the crates for any signs of
damage or rough handling. Open the crates carefully to avoid any
damage to the contents. Use a nail puller rather than a crow bar
when required.
When opening the crates, be careful that any loose items or
hardware are not discarded with the packing material. Check the
contents of each package against the packing list. Examine the
Ground and Test Device for any signs of shipping damage such as
broken, missing or loose hardware, damaged or deformed insulation
and other components. File claims immediately with the carrier if
damage or loss is detected and notify the nearest Eaton office.
Tools and Accessories
Grounding Cables (If applicable)
(Style# 94G3100G51): Grounding cables are provided only on the
cable type G&T devices. The appropriate size and number of cables
are furnished to match the rated short time and momentary ratings.
The terminated cables may be bolted to the appropriate terminals
and to the ground connections provided on the G&T device.
Grounding Shorting Bars (If applicable)
(AM 4.16 Style# 94G2105H29 - AM 13.8 Style# 94G2100H30):
Three grounding shorting bars are furnished only on hard bus-type
G&T devices. These bars may be positioned for grounding either the
three upper or the three lower terminals of a six terminal device, as
required. Bars are configured to prevent closing the terminal doors
when they are installed (Figure 3.1.d). Shorting Bars may be stored
on front of G&T.
Bushing
Knobs
(1200A Style# 7960D38H08 - 2000A Style# 94B2126H01): The
bushing knob is the silver-plated part of the moving primary
disconnect bushing assembly that engages the stationary primary
disconnect in the circuit breaker compartment. The bushing
knobs are configured for either 1200A or 2000A circuit breaker
compartments and are interchangeable on the cycloaliphatic bushing
assemblies.
Bushing
Wrench
(Style# 94G2105H42): A special wrench is provided only on G&T
devices that have interchangeable primary disconnects. These
convertible devices are equipped with extra 1200A or 2000A
terminals. This bushing wrench is recommended for removal and
installation of primary disconnect knobs to allow the G&T to be used
in circuit breaker compartments that have the same short circuit
currents available but differing continuous current ratings.
Interlock Keys:
Key interlocked terminal access doors are provided to supplement
site lock out, tag out strategies. Required by G&T standard C37.20.6,
these Kirk
®
Key interlocks prevent simultaneous access to both
the upper and lower terminals only on six terminal devices. Special
coded keys are provided for use with each G&T device. If keys are
lost or damaged, contact Eaton for replacement.
