Here's my scenario: Construction has installed hundreds Chase Nipples through sheet metal plates in the Substation flooring (no concentric/eccentric knockouts in plates), into 480V, 5kV and 15kV Motor Control Centers and Switchgear.
They have NO bonding jumpers, NO bonding-type locknuts, etc - just standard bushings on the straight-threaded Chase nipples where cables enter the enclosures.
Quality Control Inspectors are demanding they 'redo' everything, which will result in thousands of additional manhours for a project that's already $500M over budget and behind schedule.
Construction is asking for a 'work-around'. I've suggested they perform random continuity checks to ensure there are no loose connections, but this will do little to satisfy the NEC requirements or the inspectors.
Any suggestions?
