23. 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.

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.

28. Competition 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
