The yellow cords are rated at 600v, I don't have any information on the insulation type at this time. The three back cords are SJOW and go to the intrinsically safe float switches. The blue cord is rated for submergence and goes to a intrinsically safe pressure transducer (1-5 vDC). My biggest concern was physical damage and a trip hazard, and was trying to pin point a specific code governing this installation. Thanks for any help you can offer.
