Refer to Instruction Bulletin 01.4IB.51000D for
information and cautions before attempting
to insert a circuit breaker into the metal-clad
switchgear equipment. The information
and cautions found in Instruction Bulletin
01.4IB.51000D also apply to the ground and
test device. Ensure that the levering-in crank
arms at the sides of the device point in the
direction of the main disconnects.
Each ground and test device and each
compartment is provided, when required,
with a coding plate designed to ensure that
no device with less than the required voltage
or momentary current rating is placed in any
compartment. If attempting to insert an
improperly rated device into the switchgear,
these coding plates will interfere with each
other and deter the insertion of the device. The
interference occurs before the device reaches
the “DISCONNECT” position.
Do not force the device past the interference
or remove the coding plate from the
compartment or the ground and test device.
!
CAUTION
1) Inserting Ground and Test Device Into Upper
Compartment
Refer to Instruction Bulletin 01.4IB.51000D
for detailed procedures for this operation.
The same instructions apply for the ground
and test device.
2) Racking Ground and Test Device to the
Connected Position
Verify the correct ground and test device
is being inserted in the compartment of
the feeder to be grounded. Also, verify all
associated incoming and tie breakers are
open before inserting the ground and test
device. Failure to do so may result in damage
to equipment and/or injury to personnel.
!
CAUTION
Perform the following to rack the ground
and test device to the “CONNECTED”
position:
a. Verify that the control selector switch is
in the “OFF” position.
b. Push the manual push to trip paddle
on the lower portion of the front of the
device
. The levering-in
shutter will open automatically and the
trip paddle will be held captive in the
“TRIP” position.
