Q. Can “line” and “load” conductors be installed in the same raceway?

A. Service conductors cannot be installed in the same raceway with feeder or branch-circuit conductors [230.7], but line and load conductors for feeders and branch circuits can be placed in the same raceway or enclosure. For example, it is common to place the ungrounded (hot) conductor and the switch leg in the same raceway for a single-pole switch, which would be line and load in the same raceway.
