Looking for some feedback on a supply system that I am designing for a project. Our firm is not typically a design build firm but given the fairly simple nature of this project I figured we would design in-house. Just looking to see if anything jumps out as an NEC violation to anyone.
Scenario - Have a 400 amp UG meter pedestal remote mounted with 2 - 200 amp MB's 120 / 240 single phase service. We are supplying a Main lodge building, a maintenance shop and 2 small out buildings used for material processing. Feeders off of meter pedestal both enter into basement of main lodge where 1 feeder hits a 200 amp fused disconnect switch at point of entrance and then goes on to hit a 200 amp non-service rated generator ATS and then main lug 200 amp panelboard to supply circuits in that building. Other feeder hits a 150 amp fused disconnect switch and then is piped through basement of lodge exiting basement - serves no loads in that building, continues on to maintenace building. At maintenance building feeder hits a 150 amp non-fused safety switch inside building at point of entrance then a 200 amp non-service rated generator ATS then a 150 amp main lug panel to serve loads in that building. Also off this panel is a 100 amp feeder to another outbuilding where a 100 amp Main Breaker panel is served inside building at point of entrance of conductors. Another smaller building is also served off of the 150 amp panel where a 6 circuit panel board is located. Ground conductors run with all feeders and rods and / or concrete encased electrodes at all buildings. Long pulls of wire but I believe I have this design as compliant.
Thanks
