Table 300.50 Note 3 specifically states is applicable for an Industrial Establishment. Would the code allow the same adjustments to be made in the depth of conduits by adding additional concrete coverage for a data center?
The data center is question is a gated facility with a 24/7 security and maintenance staff. A MV duct bank was installed at an 18" depth not the 24" depth required by Table 300.50. Can the situation be adjusted by adding 2" of additional concrete coverage to compensate for the 6" reduction in backfill?
