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.

CompetitionPDI 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.

CompetitionPDI 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
