Question:

Are barriers needed in a switchboard to separate the fused and non fused conductors? My feeling is that the gutter space in a switchboard is not raceway and not subject to the NEC code 230.7 article 100.

Answer:

Hey Patrick thanks for your question. You are correct service conductors are not allowed in the same service raceway or service cable with other conductors as stated in 230.7. The space within a switchboard is not a cable or raceway. See the definition of Raceway in Article 100 and the many cable and raceway definitions in the XXX.2 sections in Chapter 3.
