Bussed Extension Sections (NEMA Type 3R)
Bussed Extension Sections (NEMA Type 3R)
Bussed extensions provide separation between enclosures where needed
to avoid building obstructions. The bussed extension occupies an area
19.25 in. (489 mm) H x 12.0 in. (304 mm) or 6.0 in. (152 mm) W positioned
vertically in line with the horizontal cross bus of main and branch unit
enclosures. Extensions provide additional space between the main device
and the branch unit where needed to meet local utility requirements. In this
case the main device is deeper than the branch unit, and the dimension
between the side of the main device and the centerline of the branch unit
meter socket is too close to meet minimum “clear space” requirements.

Bussed extensions are also used with bussed corner sections to provide
additional working space in inside corner areas.

•
Contact your local utility to determine minimum dimension from bottom
of main device to floor or finished grade level.
•
Refer to drawings of main devices and branch units starting on page 40
and determine proper height to install mounting channels. Ensure
branch unit meter sockets are positioned within total branch unit meter
socket height window, and main device bottom is positioned far enough
above floor or finished grade level to comply with local requirements.
•
Once the mounting channel height is determined, chalk a level line on
wall at proper height.
•
Align top edge of mounting channels for each unit to wall in the order
that they will be installed.
•
Some EZM branch sections (five-position and six-position branch units)
may not fit within utility’s meter height window for outdoor applications,
although could be acceptable for use in indoor installations.

Equipment Grounding Procedure
Equipment Grounding Procedure
1. Install mounting channels to wall at proper height (refer to “Mounting
Channel” on page 11).
2. Remove closing plates from sides of EZM main device next to where
EZM branch sections are to be installed.
3. Position units on mounting channel next to each other, but do not secure
rotating mounting brackets to wall at this time.
4. Remove outer covers EZM main device and exterior covers from EZM
branch sections (refer to page 21 for outer covers on branch devices).
5. Remove individual meter socket cover from over horizontal cross bus
area of EZM branch sections (refer to “Individual Meter Socket Covers”
on page 21).
Captive Equipment Bonding
Screws are Located on Right
Side of Each EZM Main and
Branch Device
Install Hex Nuts with
Star Washers onto
Captive Screws
6. Bond enclosures together by sliding three captive screws from the
RIGHT side of unit through holes in box side (closing plate holes), and
through LEFT side of adjacent enclosure. Install three 1/4-20 hex nuts
with star washer provided onto 1/4-20 captive screws and torque to
50 lb-in. (5.6 N•m). Bonding for equipment ground path is complete, and
enclosure gaskets are compressed to seal connection between units.
7. Replace closing plates at each end of metering equipment lineup (refer
to “Closing Plates” on page 17).
At this point, the enclosures are connected together and a bonded
equipment ground path is established. The next installation step involves
connection of the horizontal cross bus assemblies.

Visi-Tite® Nut Horizontal Cross Bus Connectors
•
The Visi-Tite nut horizontal cross bus connector is a high-strength
1/2-13 UNC double-headed torque indicating nut. Installed as an integral
part of the horizontal cross bus structure in every EZM main and branch
device, this unique nut makes it possible to ensure proper torque at each
connection without the need for a torque wrench.
•
The torque indicating Visi-Tite nut assembly also makes it possible to
reduce equipment installation time over other designs requiring the use
of a torque wrench.
•
When making EZM metering equipment cross bus connections, there is
no need for a torque wrench. Use a socket wrench with a long handle to
tighten the outer Visi-Tite nut head until it twists off and releases the
RED plastic warning disc.
•
If the RED disc remains visible during inspection, the horizontal cross
bus assembly has not yet been tightened.
•
Once the outer Visi-Tite nut head is twisted off, an inner hex-head nut
remains for use with a torque wrench on maintenance checks or
relocation of equipment (torque 50 lb-ft./600 lb-in. [68 N•m]).
•
All phase and neutral connections to the horizontal cross bus structure
are now completed.
•
The final step is to secure the rotating mounting brackets to the wall at
top and bottom of each EZM main and branch unit enclosure.

Bus Structure is Complete

Factory Phase Balancing
Phase Balancing Flexibility
The major benefit of factory phase balancing is that most jobs will not
require field phase balancing. To see if meter socket phase balancing in the
field is required (refer to wiring diagram for complete instructions):
A. Determine if the load in amperes on each phase of the transformer using
handle rating of tenant circuit breakers installed at each number of meter
sockets. Use Phase Balancing Chart to determine total number of
connections each meter socket makes on each phase of transformer.
B. If phase balancing is required, determine which meter sockets should be
changed to properly phase balance metering equipment lineup.
C. Once meter socket(s) is selected to be phase balanced, remove
individual meter socket cover from each meter socket to be phase
balanced. The vertical bus bars running top to bottom in the branch unit
behind each meter socket are phased: AØ, BØ, CØ, left to right.
D. By moving only the line side meter socket “Z” shaped connectors per
meter socket to be changed, phase balancing can easily be
accomplished on-site:

EZM Main Device Types and Configurations
EZM Main Device Types and Configurations
EZM main devices are available as main circuit breakers, main fusible
switches, or main lug terminal boxes; for use in single-phase or three-phase
applications. An EZM main device is required upstream from EZM branch
units even in the case of the NEC six Disconnect rule. EZM main devices
ending in “-CB”, “-FS”, or “-TB” are configured for overhead (top feed) or
underground (bottom feed) service, and are supplied with lugs. EZM main
devices ending in “-CBU”, “-FSU”, or “-TBU” are configured for underground
(bottom feed) service only, and are equipped with lug landing pads (lugs
must be ordered separately).
