In the default configuration of Feeder Manager, a FeederID is inherited from a connected feature only if the new feature is assigned to an energized phase. Here are some examples:
A three-phase primary connected to a three-phase primary that is energized on any phase WILL get a FeederID, while a three phase primary connected to a three phase primary that is NOT energized on any phase WILL NOT get a FeederID.
A single-phase primary on A connected to a three-phase primary that is energized on at least A WILL get a FeederID, while a single-phase primary on A connected to a three phase primary that is NOT energized on A (even though it may be energized on one or more other phases) will NOT get a FeederID.
A single-phase primary on B connected to a single-phase primary on A WILL NOT get a FeederID regardless of whether the existing A-phase primary is energized. Change the phase value of the new feature from B to A and a correct FeederID will be assigned, assuming that the A-phase primary to which you connect is energized on A.
A single-phase primary with no phase designation WILL NOT get a FeederID (nor will anything downstream).
A single phase-primary on A connected to a three-phase primary where phase A is not energized WILL NOT get a FeederID. This could occur if an upstream device on the three-phase line is open on phase A, or an upstream conductor has A-phase designation from which A is absent.
