EMT conduits were previously ran through a Parking Garage. We are bidding on a project at the receiving end. 150HP Pump, 1200 Amp Service Fused Disconnect, RHW wire. REF: 695.6(B)3 - does this apply? This was suggested in the meeting with the GC. I usually avoid a Service disconnect and/or have routed 'outside the building', so haven't used this method. How or where do I confirm (Iknow - AHJ, getting my ducks..)that this is a "listed" electrical circuit protective system, with a minimum 1 hour rating? I've read EMT is not rated, as it is not combustible and read the RHW rating, but can't put my finger on the exactness. Any help?
