Test Cabinet
Section 2. Receiving, Handling and Storage
2-1. Receiving
Each test cabinet is carefully inspected before shipment.
Immediately upon receipt of the test cabinet, an
examination should be made for any damage sustained
in transit. If injury or rough handling is evident, a
damage claim should be filed immediately with the
transportation company and the nearest General Electric
Sales Office should be notified.
It is expected that due care will be exercised during the
unpacking and installation of the test cabinet so that no
damage will occur from careless or rough handling, or
from exposure to moisture or dirt.
2-2. Handling
Normal care in handling the test cabinet will result in a
trouble-free installation and long testing life.
2-3. Storage
It is recommended that the test cabinet be put
immediately in its permanent location. If this is not
possible, the following precautions should be taken to
assure proper storage of the test cabinet.
1.
The test cabinet should be stored in a clean
location, free from corrosive gases or fumes;
particular care, for example, should be taken to
protect the equipment from moisture and dust, as
this combination has a very corrosive effect on many
parts.
2.
If the test cabinet is stored for any length of time, it
should be inspected periodically to see that rusting
has not started and to insure good mechanical
condition. Should the cabinet be stored under
unfavorable atmospheric conditions, it should be
cleaned and dried out before being placed in
service.
Section 3. Description and Principles of Operation
The test cabinet, catalog no. 0231C9827G001, G002, G003
(Fig. 1) is used to operate a Power/Vac circuit breaker that
has been removed from the metal-clad equipment. It
provides a convenient means of accessing the electrical
close and trip circuits of the breaker during maintenance
and inspection procedures.
This unit is designed to be wall or cabinet mounted. It has
an 8-foot cable (1), a storage bracket (2), control power
selector switch (4), close push-button switch (5) for closing
the breaker, trip 1 push-button switch(6) for opening the
breaker. An optional pushbtton switch is available for
testing circuit breakers that have either a 2
nd
trip coil or a
direct-acting undervoltage trip device.
An indicating light (8), connected to the close circuit fuse
block, indicates the selector switch (4) is on or off. The
indicating light is furnished from the factory with a 250V
resistor. If the close circuit voltage is 125V or less, replace
the indicating light resistor with the resistor taped to the
inside of the cabinet (9).
Inside the unit is a rectifier board (10), a stud for
attaching a ground wire (14) and fuse blocks (11,12,13)
for supply voltage fuses. There are also two holes, one on
upper left and the other on lower right to accommodate
3/8 inch studs for mounting.
CAUTION:
It is strongly recommended that the test
coupler be connected to the breaker before the power is
turned on.
