Ok placing service on old house zoned comercial. Did a service 200a metermain.Installed a 60a double pole breaker feeding a main lug 100a panel where the load is nothing 4 rooms no a/c no heat no h20 heater just a storage at feed store. Well the inspector wants exit lights added smokes interconnected.All ok but he has a problem with my feeder to the 100amp main lug panel. Its a 100 amp panel with maybe 20 amp loads I feed with a 60amp and wired based on the 60 a feeder.I need to plead my case why the installation is compliant although he can`t show non compliance.I showed him the load calcs but..... I`d just like to give some code references and such.He`s looking for a 100a main breaker and #3 copper for feeders. If I had a main of 100 I could see his point but still i`d like be able to use code for my point or heck If I`m wrong I`d like to know why by code. Thanks again ps i`m looking also in the code.
