Pow-R-Command 100 Column Panels
The Pow-R-Command 100 Column Panel is a
specialized distribution panelboard designed
to fit in the width of a standard I-beam,
commonly found in manufacturing facilities
and warehouses. The Pow-R-Command 100
Column Type Panel allows a complete
lighting control system to be installed in a
narrow space. Because of space and use
constraints of the column type panel, the
optional Pow-R-Command 100 features (e.g.
expansion chassis & associated SOC) found
in a standard panelboard are not available.

Standard Panelboard Components
Two assemblies are added to a standard
panelboard too make it a Pow-R-Command
100 panelboard. The first is a 5X control
chassis, which contains the appropriate
power transformer, line protection, Rail
Interface Board (RIB), and USC. The second
is a control bus known as Breaker Termina-
tion Board.
Control Power
: The electronics in a Pow-R-
Command 100 system, as well as Smart
Breaker, are powered from a 28V ac source
from a supplied Control Power Transformer
(CPT). The Control Power Transformer
used is a dual tap transformer capable of
operating at either 120 V ac or 277V ac.
Power to the trans former is drawn directly
from the bus. Additionally, line protection is
supplied to both the primary and secondary
side of the transformer. Furthermore, a line
filter is installed upstream of the CPT to
provide greater protection to the USC’s
circuitry.
Universal Systems Controller
The Universal Systems Controller is a control
device used to control the switching
devices in the panelboard. The USC is
mounted to the Rail Interface Board in the
5X control chassis.
Rail Interface Board
The Rail Interface Board is a bridge between
the USC and the Breaker Termination
Boards. In addition, the Rail Interface
Board contains terminal blocks used to
locally terminate the Pow-R-Command 100
network.

Column Type Panel
Breaker Termination Board
Like the Breaker Termination Boards found in
the Pow-R-Command 100 Panelboard, the
Breaker Termination board in the column
panel acts is a control bus. It delivers control
power to each Smart Breaker in the panel
and returns a status signal to the USC. The
Pow-R-Command 100 column panel contains
one long Breaker Termination Board that runs
the length of all branch circuit breakers.
Available Branch Circuit Breakers:
Because the Pow-R-Command 100 Panel-
board uses standard Pow-R-Line 1a- & 2a-LX
designs, the same types of branch devices
can be used. For 480V ac and applications
and below GHB, GHBS, & GHQRS type
branch devices can be used and intermingled
in the layout of the panel. GHBS & GHQRS
are 1-inch bolt-on Smart Breakers. For 240V
ac applications and below BAB, BABR, &
BABRS type branch devices can be used and
intermingled in the layout of the panel. BABR
& BABRS are 1-inch bolt-on Smart Breakers.
