Residential Meter Stacks
Features, Benefits and Functions
A. Barrier
Meter socket and tenant
main breaker/wireway
sections are separated by a
solid metal barrier to guard
unmetered bus against
power theft.
B. Tenant Breaker
Reliable busbar–to–busbar
connection. 200 A modules
accept bolt-on breakers 60–
200 A. 125 A modules accept
15–125 A plug-on breakers.
C. Moveable Phase Connector
Four-wire horizontal bus lets
you use any 3MM module
for single- or three-phase
incoming service. Shipped
with A and B phase
connection, phase balancing
is easily accomplished in the
field by moving one, front-
accessible phase connector
post per module.
D. Neutral Assembly
A convenient termination for
neutral conductors is in the
wireway of each module.
E. Enclosed Horizontal Bus
Added security because a
non-removable barrier
encloses the 800 or 1200 A
horizontal bus passing
through tenant breaker
section.
F. Equipment Ground Bar
Factory installed in side
gutter, a standard feature
that’s moveable to the top or
bottom gutter.
G. Raintight Cap
Shipped on each outdoor
meter module and main
device.
H. Knockouts
Tangential in bottom endwall.
I. Superior Finish
Rust inhibiting phosphate
primer and gray baked
enamel is standard. All
outdoor enclosures are of
galvanized steel construction.
J. Meter Socket
Our unique meter socket
base is installed without any
fasteners—reducing chances
for hot spots, easily
replaceable, and improves
connection to vertical bus.
K. Bus Connection
Mains and modules slip
together quickly and
smoothly with front-
accessible captive bolts
securing the juncture without
removing socket interiors or
bus access plate. Main bus
joint bolts torque to 25 foot
pounds.
L. Separate Wireway Cover
Separate covers allow easy
access to tenant breaker and
wireway section, permit work
on breakers or in wireway
without disturbing meters or
meter covers. (Not shown.)
M. Vertical Busbar
One-piece vertical busbar
from phase balancing joints to
meter socket eliminating any
chance for hot spots.
