Help please. Under article 310-15 "Notes to ampacity tables" 8(b) spacing between conduits, tubing or raceways shall be maintained." My question is what is the minimum spacing for conduits in an underground instalation. This is a 480/277 service. Do you use figure 310-1 for spacing?

About 18 years ago that question was answered in an electrical magazine with words similar to (para-phrasing); conduits kept at the spacing required for installation of locknuts and bushings should meet that spacing requirement.

Along this same question, are 2 or more RNC conduits bundeled together stubbed-up out of a concrete pour required to provide for this spacing, 352.46 ?
