I am installing a Trenwa trench system and am installing 4160V, 480V, 120V and 24V in the trench. This trench is going to be filled with sand once the cables are installed so the area classification will not be Div. I.
I would lke to know how to derate the cable going into the trench or where...
Does anyone have any suggestion on what equipment I can use to shutdown a 2400 volt motor that is 3000' away from a control house or have any idea on how this should be done?
Thanks

Are there any standards for grounding of a ring crane?
We were installing a ground loop with three ground rods and bonding the tracks together. Will this be sufficient?
Thanks
