EZ Meter-Pak® Meter CentersBussed 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.

• Use EZM1EXT6 (6.0 in.) or EZM1EXT (12.0 in.) wide.

• Use EZM3EXT6 (6.0 in.) or EZM3EXT (12.0 in.) wide.


• Provisions for padlocking or sealing by the utility.

Bussed Corner Sections for Indoor (NEMA Type 1) Construction Only• Enables mounting of metering enclosures on two adjacent walls.

• NEMA Type 1 construction for use indoors only.

• Designed for “inside and outside corners”.

• Use EZM1CORNER (inside corner) with 1Ø cross bus equipment.

• Use EZM1ELBOW (outside corner) with 1Ø cross bus equipment.

• Use EZM3CORNER (inside corner) with 3Ø cross bus equipment.

• Use EZM3ELBOW (outside corner) with 3Ø cross bus equipment.


• Provisions for padlocking or sealing by the utility.

Mounting Channel (see page 12)

• EZM main and branch units are each supplied with a wall mounting channel.

• Mounting channel is packed externally to each device on top surface of front cover inside each carton for easy access. Covers do not need to be removed from device to access mounting channel.

Rotating Mounting Brackets (see page 12)

• EZM sections are equipped with permanently attached swinging mounting brackets that are easily rotated out of the way after marking wall for drilling mounting holes. The rotating feature of the mounting brackets will accommodate slight mounting hole misalignment.

• Rotate mounting brackets to extended position before lifting device onto mounting channel for ease of installation.

• Rotating mounting brackets are provided at top and bottom of each unit to secure device to the wall.

Determine Mounting Channel Height for Metering Equipment Lineup

• Contact your local utility to determine the following branch unit meter socket mounting height restrictions:

— Maximum dimension, centerline of top meter socket to floor or finished grade level

— Minimum dimension, centerline of bottom meter socket to floor or finished grade level

— Total branch unit meter socket height window (maximum dimension less minimum dimension).

• 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.

EZ Meter-Pak® Meter CentersEquipment 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).

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.

EZ Meter-Pak® Meter Centers 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:

To change an AØ and CØ meter socket to a BØ and CØ meter socket:
