Solar Power Center Loadcenters and Meter Breakers
Product Description
Eaton’s Solar Power Centers
combine both utility power
and solar photovoltaic (PV)
power into one enclosure.
Solar Power Centers can be
applied as a component
of a complete PV electrical
system. Eaton offers the
most complete line of
Balance of System (BOS)
products in the industry,
along with a wide
variety of configurations
including loadcenters and
meter breakers.
The Solar Power Centers
feature industry-exclusive
factory-installed permanent
markings, which help to
ensure National Electrical
Code
®
(NEC) compliance.
Required by the NEC, these
markings enable quick and
easy identification of product
ratings and location of the
parallel energy source
disconnect. Prior to installation ,
contact your local utility to
confirm approval.
Product Types
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 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.
Meter breakers are service
entrance equipment that
consist of a single meter
socket and loadcenter (circuit
breaker distribution section)
or meter socket and main
breaker combined in one
enclosure. Sometimes called
Combos, All-in-Ones, Meter
Centers or Meter Mains,
these units are increasing in
popularity as the socket and
loadcenter or main breaker
are located in one location,
thus providing the contractor
with a labor and material
savings when installing.
Meter breakers are most
often sold in the western,
southwestern and
southeastern United States.
The popularity of meter
breakers is continuing to
increase as more utilities
deregulate and pass the
responsibility of supplying
watthour meter sockets on
to the electrical contractor.
