It's been a while since I last posted and I hope all is well for everyone. I must admit that I feel rather foolish even asking a question like this but I could find nothing in the code or any refererance material that I came across pertaining to my problem so here it goes. The corperation that I work for recently closed down a plant in Canada and sent some of the equipment to the plant that I work in - all motor voltages are 575 Volts and they are running at 480 volts. I have voiced my concern but no one seems to want to be accountable for having them on the floor. Now the plant Manager has told me that I have to look for the "grey area" in the code, but this seems more like a grey area in the laws of physics! I am sure that any arguements that I make will fall on deaf ears, but I would like to know what to expect as noone that I know has ever heard of such a thing. Thanks in advance.
