Since the ground and test device is an
accessory device not normally in continuous
service, it is very important that it be stored
carefully so that it will be available when
needed. The following precautions must be
taken to assure proper storage of the ground
and test device:
1. Since moisture has an adverse effect on
the insulating parts, the device should be
carefully protected against condensation,
preferably by storing it in a warm dry room
of moderate temperature, such as
40°-100°F. Ground and test devices used in
outdoor metal-clad switchgear should be
stored in the equipment only when power
is available and the anti-condensation
heaters are in operation.
2. The ground and test device should
be stored in a clean location free from
corrosive gases or fumes. Particular care
should be taken to protect the equipment
from moisture and cement dust, as this
combination has a corrosive effect on many
parts.
3. Unplated surfaces, such as, rollers, latches,
etc., of the operating mechanism should be
coated with grease/oil to prevent rusting.
If the ground and test device is stored for
any length of time, it should be inspected
periodically to see that rusting has not
started and to ensure good mechanical
condition. If the ground and test device
is stored under unfavorable atmospheric
conditions, it should be cleaned and dried
before being placed into service.
4. The device should be covered with a
cloth or plastic cover to prevent dust
accumulation on the device during long
term storage. This cover must not cut off
air flow to the device or condensation may
occur under the cover.

In order to check the basic electrical operation
of the ground and test device, the device must
be placed near a circuit breaker test cabinet.
1) Test the Closing Operation of the Ground and
Test Device
Perform the following to test the closing
operation of the ground and test device:
a. Connect the secondary disconnect plug
from the test cabinet to the secondary
disconnect receptacle on the ground
and test device
.
b. Ensure the Key KA is captive in Lock K1
c. Connect the power cord of the remote
control box to the ground and test
device and rotate the plug clockwise to
.
d. Turn the test cabinet power “ON” and
verify that the control selector switch is
in the “OFF” position
.
e. Move the control selector switch to the
“CLOSE” position.
f. Turn the remote control box to the
“ON” position and depress the “CLOSE”
button.
g. Move the control selector switch to the
“OFF” position.
2) Test the Opening Operation of the Ground
and Test Device
Perform the following to test the opening
operation of the ground and test device:
a. Perform steps a through g of Test
Closing Operation of the Ground and
Test Device.
b. Move the control selector switch to the
“OPEN” position.
c. Turn the remote control box to the “ON”
position and depress the “OPEN” push
button to open the ground and test
device.
