Residential Power After passing through a meter, incoming power usually goes
Distribution to a load center. Load center is an industry term used to identify
a type of panelboard used in residential or light commercial
applications. As previously indicated, this load center may be
combined in the same enclosure with a meter socket. Often,
however, a separate load center is provided. In some instances,
typically where there has been subsequent construction,
a second load center is used for additional circuits. Where
a central air conditioning unit is used, an electrical service
disconnect device is often provided to remove power from the
unit while maintenance is performed.

Load Centers A typical load center consists of an enclosure, interior, and trim.
A load center may have a main circuit breaker, but, if a main
circuit breaker is provided separately, a main lug only type load
center can be used. Branch circuit breakers plug into the interior
to provide circuit protection and control for branch circuits. Load
centers vary in size and ratings. For example, Siemens PL and ES
load centers are available with continuous current ratings from
100 to 225 amps.
