B. Pedestal and Pole-Mount Cabinets
1.1
The 3M™ Modular Hardwire Cabinets 4300
1.3
Series provide a point for cross connections
between feeder and distribution cables of diameter
0.7 mm–0.32 mm (22–28 AWG). Frames within
the cabinets hold banks of preconnectorized 25-pair
feeder and distribution blocks. Blocks can either be
installed initially or added at a later date with no
disruption of existing circuits.
1.2
Jumpering is accomplished using 0.7 mm
(22 AWG) plastic insulated wire which is run from 1.4
feeder binding posts to distribution binding posts.
Wire raceways are provided for protection of all
1.5
jumper pairs as they are installed.

Due to the terminal sizes and frequency of installation
visits, the cabinets should be located as specified by
the engineering plan. The cabinets should be located in
unobtrusive locations acceptable to the property owners
and where they are reasonably protected from damage
by motor vehicles and other machinery. They should be
1.5 m (5 feet) from utility poles and at least 0.3 m (1 foot)
from buildings, fences, or other objects considered to be
potential lightning attractions.
The cabinets are constructed of galvanized steel with a
gray/green baked enamel finish.
The pedestal cabinets feature a ventilation system
whereby the vents may be open or closed depending on
local condensation conditions.

The 3M™ Modular Hardwire Interface 4365 is a
200-pair cabinet that can either be ground mounted
or pole mounted (with 3M™ MS2™ Pole Mount
Conversion Kit 4098). The cabinet includes a talk
block, jumper wire spool mounting bracket, bond
bar and space for 3-pair drop wire blocks, using the
3M™ Terminal Block Bracket 4064.
2.2
3M™ Modular Hardwire Interface 4382
The 3M™ Modular Hardwire Interface 4382 is a
stake mounted pedestal cabinet holding 600-pair.
The cabinet includes a talk block, jumper wire
spool mounting bracket, external bond plate and
space for 3-pair terminal blocks.
2.3
3M™ Modular Hardwire Interfaces 4384 & 4386
The 1200-pair 4384 and 1800-pair 4386 Modular
Hardwire Interfaces can be either stake or slab
mounted. The double sided cabinets have fold
down frames for cable routing access and include
a talk block, jumper wire spool mounting bracket,
external bond pair and space for 3-pair drop wire
blocks.
2.4
3M™ Modular Hardwire Interface 4395
The pole-mounted 3M™ Modular Hardwire
Interface 4395 holds 1200 pair. Cable entry can
be either through the top or bottom. The cabinet
includes mounting brackets, talk block, jumper wire
spool mounting bracket, external bond plate and
space for 3-pair terminal blocks.
B. 3M™ Modular Hardwire Block 4310-25
(See Figure 1)
2.5
3M™ Modular Hardwire Interface 4365
The 3M™ Modular Hardwire Block 4310-25
contains 50 binding posts to accommodate 25 cable
pairs. The blocks are preconnectorized to a 3M™
MS2™ Super Mini Module Body/Cover 4000 D.
The right-ring-binding post is colored red on the
otherwise white modular hardwire block. factory
sealed rear connections are potted in resin for
protection against moisture and other environmental
hazards.
The 3M Modular Hardwire Block 4310-25 NC is a
white modular hardwire block with no connectors
and color coded leads.

A. 3M™ Controlled Feeder Block 4311 (Green)
1. Controlled Feeder Block Description
9.1
The 25-pair binding post Controlled Feeder Block
contains 50 binding post tereminal switches. The
terminal post pulled OUT to the locked position
express the feed cable through the cabinet with no
local termination. See Figure 67
Figure 67: Terminal Post OUT, Feed Thru
78-0013-1943-9-A25
9.2
When the terminal post is pushed IN to the locked
position, the feed is then terminated. See Figure 68.
9.3
The feeder cable is spliced to the black
preterminated conductors (3M™ MS2™ Super Mini
Body/Cover 4000 D) and the field cable is spliced
to the white preterminated conductors (3M™ MS2™
Super Mini Body/Cover 4000 D). The right-ringbinding post is colored red on the otherwise green
3M Controlled Feeder Modular Hardwire Block.
Factory sealed rear connections are potted for
protection against moisture and other environmental
hazards. The Controlled Feeder Binding Post
Blocks are identical in size to the standard 25-pair
hardwire block and can be used in any of the
standard pedestal and pole mount cabinets.

3. Controlled Feeder Block Splicing Instructions
9.5
Splicing controlled feeder blocks is the same as
splicing modular hardwire blocks EXCEPT feed
in and feed out cable must be spliced for each
controlled feeder block.
9.6
Begin splicing procedure by following Section 7.0
paragraphs 1 through 4.
9.7
Splice FEED IN (Black) TAIL first. Holding groups
behind head with guide hand, use thumb and
forefinger to place each pair in the wire guide to the
right of its matching color and splite the pair over
the pair separator, TIP – left, RING – right. See
Figure 69.
9.8
Splice and crimp conductors according to Section
7.0, paragraphs 6 through 15.
9.9
After FEED IN (Black) TAIL is spliced to 'feed in'
module, splice FEED OUT CABLE to 'feed out'
module, following the procedure outlined in Section
7.0 paragraphs 5 through 15.

connect and trim the jumper wire with a 90º turn
of the cap. The 4320 Blocks are dimensionally
compatible with all pedestal and pole mount
cabinets used in the 3M™ Modular Hardwire
System 4310.

3M™ Self-Strip Pair Test Connector 4328
10.15 The 3M™ Self-Strip 25 Pair Test Connector 4328
provides access for test equipment to the 3M™ SelfStrip Terminating Block 4320. The test connector
connects to test equipment with a female Cinchtype connector.
Attaching the Test Connector
a) Remove the plastic protector cover.
b) Holding the test connector around the rear cord
strain relief, swing the handles out and push clamps
to forward position.
c) Align the test connector in front of the block to be
tested. Make sure the test connector is right side up
(label up). Push in the test connector to compress
the test pins against the elements in the caps. Slide
the extended clamps under and against the inside of
the block tabs.
Note: 3M™ Self-Strip Priority Caps 4324 allow self
strip block to be tested with the test connector,
making connections to all circuits except
those with priority caps in place. The holes in
the cap permit partial insertion (no electrical
contact) into special circuit ports.
