quIpment
Refer to the appropriate instruction bulletin for
information and cautions before attempting to
insert a ground and test device into the
metal-clad switchgear equipment. The
information and cautions found in 01.4IB.65071
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
an interference 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 interference 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
plate or remove the interference plate from
the compartment or the ground and test
device.
!
CAUTION
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 & test
device. Failure to do so may result in damage
to equipment and/or injury to personnel.
!
CAUTION

General Description, 2) Inspection and
Cleaning .
If the primary disconnecting devices are

ensure that it is clean and clear of debris
that might interfere with ground and
test device travel.
