During commissioning of a 3-phase motor, the technician measures 480V L1-L2, 480V L2-L3, but only 277V L1-L3. What is the MOST likely problem?
-
A
The motor is running in reverse rotation
-
B
One phase conductor is open (open phase condition)
-
C
The motor windings are shorted phase-to-phase
-
D
The power factor capacitors are incorrectly sized
