Frequently asked questions
● Can the new BCPM printed circuit board (PCB) be used to replace the
old BCM PCB for a retrofit application?
● No. The CT strips shipped with the BCPM are different from those used with
the BCM and therefore wont work when interchanged.
● What is the standard length of the ribbon cable shipped with the BCPM?
● Three feet
● Does the BCPM support various type breaker (single, 2 and 3 pole) in a
single panel?
● Yes, but this type of installation must be performed by PowerLogic Services
due to the complex register mapping for this device.

PDI BCMS and BCMS Plus - Measurements
● Two feature sets available: BCMS and
BCMS Plus
● BCMS measures current only
● BCMS Plus adds voltage measurements
and power and energy at the panel
board level
● The BCMS and BCMS Plus do not
monitor the mains current. They sum the
branch breaker currents to report current
per panelboard.

PDI BCMS and BCMS Plus - continued
● BCMS Plus differs from the BCPM in the following ways:
● No No inputs for Mains CTs. The BCMS does not monitor mains current, but
instead calculates total current by summing the individual current values for
each breaker
● The BCMS only reports power and demand values for the entire panel
board, not per phase
● The BCMS quotes 2% accuracy for measured current, but does not give an
accuracy range Accuracy: Current – 2% or 0.1 Ampere, whichever is
greatest
● BCMS specification does not provide a range of current where it is accurate
● PDI has suffered in the past from poor product
quality and questionable accuracy
● PDI makes hardware only and is not able to sell
a system or end-to-end solution
