A

Answer:

Hey Jim thanks for your question. Yes, spacing between raceways is required, as you mention, as stated in 310.15(B)(3)(b). That is the section subdivision reference. No specific dimension is provided for the spacing but the spacing achieved by fittings and support means is generally accepted.
