Are GFI receptacles required inside Insudtraial Mill Buildings? One example is a grinding mill inside a steel structure building that has siding on it. There are various pieces of equipment inside the building (compressors, hydraulic skids, etc..)
I know NEC requires GFI receptacles to be located outdoors but what about inside a building as described?
