BCMS CB (Subfeeds) Readings
The short BCMS CB (Subfeeds) points list is associated with panelboard BCMS Normal or KWH
points lists and provides current readings for two subfeeds (Figure 28). It is typically used with an
RPP, which can have subfeeds to other power distribution equipment in addition to its panelboards. It
is not used with large subfeed PDUs, which use the Enhanced Subfeeds (ESF) points list.
A BCMS Data Acquisition PCB can have three Modbus addresses: two panelboards with BCMS
Normal or KWH points list and a third BCMS CB subfeeds points list.

BCMS IEC Readings
BCMS IEC panelboards have three readings screens (Figure 29). For panelboard 1, individual circuits
are numbered 1L1 to 1L72. Panelboard circuits are numbered sequentially down the left side (1L1-
1L36) and then down the right side (1L37-1L72).
BCMS IEC points list does not have the BCMS CB subfeeds option.

The
BCMS CB
device for panelboard
subfeeds has current readings for one or
two subfeeds:
•
Current, phases ABCNG
•
Maximum current, phases ABC
Points list options let you choose monitoring
for
•
Sub-distribution feeds 1 and/or 2
•
Phases ABC
•
Neutral (optional)
Ground (optional)
In this example, subfeeds 1 and 2 are
monitored for phases ABC, but not NG.
