We have a large Ransome welding manipulator system with a boom that's setup for TIG welding and plasma welding. It has various controls on it, but for some reason it's being powered from a few different locations. They are all 480V. I want to have everything to be powered from one power distribution box, but I need to justfy the expenditure. What are some of the potential hazards or disadvantages of being powered from multiple locations.
Thanks
