I have a project on a piece of equipment at a precast concrete plant.....they bought this tilt table (not exactly sure how it works, havent seen it run yet) but it is 480V three phase. It is outside, will always be outside. It will be moved from time to time, in the same area but pipe/sealtight and wire is not a option.
So, SO cord and a plug it is (twistlock).
The service at this plant is a ungrounded 480V three phase, no actual ground (you can get a reading to ground, but if equipment faults to ground, it will energize whatever; conduit, enclosures, etc) so the idea of a 'assured equipment grounding conductor program' seems like it would be worthless here to me....
What do you do in a situation like this?
