between low voltage and medium voltage sections within a
switchgear section, use the openings provided.
d) Once the wiring is completed, reseal the openings through which
the wiring passes. There are two types of sealing systems: one
is a non-adjustable opening (see Figure 98 ) and the other is an
adjustable opening (see
Figure 99
and
Figure 100
). Refer to the
applicable section that follows to complete this process.

voltage sections.
Figure 99. Adjustable - medium-voltage side.
Figure 100. Adjustable - low-voltage side, fixed opening
e) If it is necessary to install additional wiring between any
sections in the front of a switchgear vertical section, it is neces-
sary to remove the factory installed caulk, install additional
wiring, then reapply caulk as described in paragraph f) or para-
graph g) below.
f) Fill all wiring openings through which wiring passes from the
center mounted low voltage compartment to medium voltage
compartments with caulk as shown in Figure 99 . Bundle wires
together on each side of the opening with a wire tie prior to
applying caulk (silicone sealant certified to MIL -A-46106,
Type I).
g) Fill all wiring openings through which wiring passes from
the center mounted control compartment to the upper front
compartment or to the lower front compartment (see
Figure 100 ). Bundle wires together on each side of the opening
with a wire tie prior to applying caulk (silicone sealant certified
to MIL -A-46106, Type I).
Adjustable opening
h) If it is necessary to install additional wiring between any
sections in the front of a switchgear vertical section, or to install
wiring from external equipment, it is necessary to disassemble
the wiring pass-through system, install additional wiring, then
reassemble the wiring pass-through system as described in
paragraph i) or paragraph k) below.
i) Wrap gasket material 1C19549H01 at least 1½ times around the
wire bundle where it passes through the opening of the pass-
through system.
j) Slide the movable plate of the pass-through system until the
gasket is compressed and fills the opening completely. Tighten
hardware to fasten the plate in place.
k) Place a 3/16” wide wire tie about 1/2” (12.7 mm) from the edge
of the gasket material on each side of the opening.
Customer installed external control wiring entering the top or bottom
of a switchgear vertical section
l)
For top entry of external low voltage conductors, there are two
removable cover plates (see Figure 101 ) on the top front of
each vertical section .
Water-tight conduit hubs or water-tight gland fittings must be
mounted in the cover plates to pass multi-conductor jacketed
cables or multiple unjacketed wires ran in conduits into the
switchgear .
If bundled unjacketed conductors are to be brought into the
front section of the switchgear, they must be brought through a
water-tight conduit hub in a workmanship manner (protection of
insulation), then the conductors must be bundled together and
conduit hub filled with caulk as described for the internal wiring
in paragraphs f) and g) above .
