Hi Guys (and ladies, of course): I need a little learnin' here. A church in this area is undergoing a service upgrade. There are four separate raceways being installed to provide a three phase service. Each one, equipped with weatherhead, travels along the back side of the church building for a distance of about 50 feet before elbowing through the wall into a switchgear room. So far, the conductors for the three hot legs (color-coded black, red and blue - three conductors per leg) have been pulled into the conduits. However, unlike what I've read, and seen discussed here previously, all three black legs are in one conduit, all three reds in another, and all three blues in the third (instead of one of each appearing in each conduit). The fourth conduit is empty at present - I assume that the "neutral" is supposed to go here.

I thought that this was strictly a NO-NO, and serious problems could result from this. Can y'all elaborate on this for me?
