Hi all, I have a small design where the customer has a wireway that feeds two meters/services; one is a small single phase DS and the other is a small three phase DS. This particular design has one single phase inverter interconnected on the single phase service, and another single phase inverter on the three phase service. My questions is, would there be a design preference for selecting conductors/phases to interconnect with on the line side of the three phase service? Is there any benefit to matching the same two phases that are feeding the single phase DS? Or varying them?
My initial thought was that it doesn't really matter as its utility side conductors, and the fact that they're physically connected by a wireway doesn't overrule the fact that they are technically separate services and could in theory be in two separate buildings. But, if there is a tangible benefit to selecting two specific conductors for the three phase DS over any combination of the other two, then might as well incorporate that into the design. Thanks!
