Post subject:  Modeling an extruder in skm
Hello,
My field tech gave me a drawing of an extruder control panel and I don't know how to model it in SKM.
Two breakers are from a panel and then they go into the control panel. inside the control panel is another breaker that feeds the drive. How do I show that in SKM?

What you have will work. Effectively, you must analyze separate points representing the different inputs into the cabinet. You will then apply the arc flash label associated with the worst case hazard. Note that the worst case arc flash hazard is likely from the lower voltage feed but the maximum voltage exposure will be from your separate 480V circuit.
