Our design engineering contractor is proposing surface routing a group of outdoor 480 volt MC-HL feeder cables along the top of the gravel pad at a remote industrial facility. This seems to me a violation of the 24 inch minimum cover requirement of Section 300.5(A). The engineer says the cables are not required to be buried or routed via cable tray because they will be protected by concrete jersey barriers and routed behind buildings.
Is this practice permitted?
