Just ductseal in the conduits?

344.46 Bushings. Where a conduit enters a box, fitting, or other enclosure, a bushing shall be provided to protect the wire from abrasion unless the design of the box, fitting, or enclosure is such as to afford equivalent protection.



So if it doesn't ENTER the box, fitting, or other enclosure, this doesn't apply??

I agree with Yoopersup. Regardless of any HV specific clauses, 250.190 requires any metal that's likely to become energized must be bonded to the building ground, which implicitely requires the cabinet and conduits be bonded to a common point.
