In our research lab we are setting up a VFD to run an experiment.
The power comes into the building through a 45 kVA, 240 V, three-phase transformer and the project will be powered from a 240 V three-phase outlet connected to a 40 A breaker.
From the outlet it will run through a 15 kVA, 240 V - 480 V three-phase step up transformer to power a 15 kW VFD which will drive an 8 kW motor.
Should I be taking arc flash preventative measures for this such as enclosures or cabinets? Cabinets are really expensive and this is a test bench, not a permanent installation. I'm not sure when the point is where risk of arch flash becomes intolerably high.
