Loadcenters and Circuit Breakers
Type BR Loadcenters and Circuit Breakers
Product Description
Loadcenters are enclosures
specifically designed to house
the branch circuit breakers
and wiring required to
distribute power to individual
circuits. They contain either a
main breaker when used at
the service entrance point or
a main lug when used as a
sub-panel to add circuits to
existing service. The main
breaker protects the main
entire panel and can be used
as a service disconnect. The
branch breakers protect the
wires leading to individual
electrical loads such as
fixtures and outlets.
Features, Benefits and
Functions
Loadcenter Construction
Eaton’s Type BR loadcenters
have standard tin-plated
aluminum bus with a limited
availability of copper bus.
The sum of the handle
ratings connected to any stab
is limited to 150 A maximum
on the 100 and 125 A
loadcenters, and 200 A on
loadcenters with 150 A or
higher main bus. NEMA
Type 1 boxes or enclosures
are manufactured from
galvanized steel. Raintight
boxes are manufactured
from galvanized steel, then
finished using an electrostatic
powder coat, baked urethane
paint process.
Neutrals
Eaton Type CH loadcenters
feature two types of neutrals:
Insulated/Bondable Split
Neutral
Panels are supplied with split
insulated neutrals with an
insulated cross strap. For
service entrance applications,
the neutral must be bonded
by using the bonding strap
supplied with the panel. For
non-service entrance (sub-
panel) applications, the panel
may be installed with the
bonding strap not connected
to the neutral. Separate
ground bars must be used on
non-service entrance panels.
Insulated/Bondable Single
Neutral
Panels are supplied with a
single insulated neutral. For
service entrance applications,
all that is required to bond the
neutral is to loosen the
bonding screw and the
neutral screw directly beside
it, insert the bonding strap
into the neutral bar, and re-
tighten both connections. The
single neutral can be moved
by the contractor to the other
side of the panel, if desired.
When used as a service
entrance panel, unused
neutral connections may be
used for the termination of
equipment grounds. For non-
service entrance (sub-panel)
applications, the panel may
be installed with the bonding
strap not connected to the
neutral. Separate ground bars
must be used on non-service
entrance panels.
Grounds
In service entrance
applications where the
neutral is bonded, unused
neutral holes may be used
for terminating ground
conductors. In sub-feed
panels, the neutral must be
isolated (non-bonded), and
ground wires must be
terminated on a separate
ground bar.
The insulated/bondable
single/split neutral panels
have sufficient terminations
for both ground and neutral
conductors. The insulated/
bondable single split neutral
panels are supplied with a
separate factory-installed
ground bar if the catalog
number contains a “G.” If
not, a separate ground bar
should be installed. Insulated/
Bondable Single Neutral
panels are supplied without
a ground bar (unless
otherwise noted), and ground
bar kits if needed must be
purchased separately.
Neutral and Ground Terminals
The standard terminals on
grounds and neutrals are
rated to accept (3) #14–#10
Cu/Al or (1) #14–4, provided
the cables terminated are of
the same material. For larger
cables, add-on neutral lugs
may be ordered from the
accessories on Page
V1-T1-66.
Note: NEC allows only one
current-carrying conductor
per hole on neutrals unless
otherwise noted.
Bottom Fed Loadcenters
For single-phase 225 A and
below loadcenters that are
bottom fed, a standard panel
can be rotated 180 degrees
to allow straight-in wiring of
power cables to the main
terminals. Because the main
circuit breaker handle
operates horizontally, the
orientation of the main circuit
breaker handle is consistent
with the requirements of NEC
2008 Article 240.81.
Gutter Splicing
Loadcenters are not UL listed
as wiring troughs. Therefore,
gutter splicing of riser cables
to tap off to the main device
is not permitted. Refer to
NEC 2008 Article 312.8.
Fire Rating
Due to the numerous
openings in both loadcenter
boxes and trims, they should
not be mounted in firewalls.
There is no approved method
for sealing the enclosures for
this application.
Date Code
The date of manufacture of
each loadcenter is printed on
the outside of the carton as
well as inside the loadcenter.
On the carton, the date code
is printed on the end carton
label. In the loadcenter, the
date code is located on the
small white label located on
the right side wall (with the
main device on top).
The date code is in the
following format: F # # # &.
The “F” is the numeric
code for the Lincoln, IL
plant, and the three numbers
are the year and week of
manufacturing, e.g., 023. The
“!” sign at the end signifies
the decade of the 2010.
Therefore, the date code
F023& would indicate
that the product was
manufactured in the 23rd
week of 2010. The 1980s
are represented by the “+”
sign and the 1990s are
represented by a “=”
at the end of the code.
Surge Protectors
Complete home surge
protection is available in
multiple options, including
a factory-installed option that
provides the highest level of
surge protection in a
residential design. See Tab 3
for more details.
