Features, Benefits
and Functions
A. End Walls
The top cap is removable and
does not contain knockouts,
so contractors can position
and punch holes where they
need them. There are
numerous KOs in the back
and bottom for flexibility.
B. Ground Bars
The factory-installed
equipment ground bars are
provided in both the top and
bottom gutters.
C. Meter Socket
The 5-jaw meter socket and
7-jaw meter socket includes a
built-in manual bypass and jaw
release. The ground wire is
factory connected in both
35MM and 37MM modules.
D. Separate Wireway Cover
If work on the breakers or
cables is necessary, it can
be accomplished without
disturbing the meters or
meter covers, thanks to a
separate cover that allows
easy access to the module’s
main tenant breaker and
wireway section.
(Not shown.)
E. Barrier
A solid metal barrier
separates the meter socket
section from the tenant
breaker in the wireway
section. The unmetered
vertical bus is enclosed to
guard against power theft.
F. Neutral Assembly
Located in the wireway of
each module, the assembly
permits convenient
termination of the neutral
conductors.
G. Enclosed Horizontal Bus
Non-removable metal barrier
encloses 1200 A horizontal
bus when passing through
the tenant breaker section
for added security.
H. Tenant Breaker Range
All modules accept 15–225 A
bolt-on breakers in various
AIC ratings. The CHH_X
breaker carries a UL listed
series rating of 100,000 A,
which allows you to use
standard 10 kAIC breakers in
downstream loadcenters and
panelboards by Eaton.
I. Indoor/Outdoor Construction
Raintight caps, meter covers
and lockable raintight tenant
breaker covers make it
convenient for you to use
any of our modules on either
NEMA 1 or NEMA 3R
applications.
J. Mounting Rail
Rear mounting rail and wall
hanger speed and simplify
installation. (Mounting rail
not shown.)
K. Nameplate and Ratings
The nameplate gives you full
rating data: 208Y/120, three-
phase, four-wire; 240/120,
three-phase, four-wire delta
(high leg on B-phase); and
240/120 single-phase.
(Not shown.)
L. Mains and Modules
Slip together quickly,
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.
