Greetings All, I would like to show the actual dollar savings if we shut down machinery at work during lunchtime. I know basic electric theory, but could use a hand from someone with an industrial background. Basically, no one is shutting down our punch presses during breaks. The motors are 3 phase and either 220 or 440. I could find out the kilowatt rates that we pay. What else do I need and how do I plug the numbers in to come up with a dollar amount for every hour that they let the motor run? I know that I need the amperage from the motor nameplate. I have seen electric questions here bring on a flood of both replies and arguments, I don't want to see that happen. If the thread gets too long, just let it die and we'll all keep to WWing........ Many thanks, Mark
