We are building a piece of equipment to be used in a class 1 Div 1 location. I am somewhat confused by what exactly is required to run conduit between a terminal box on the back and a bank of 6 solenoid switches on the side of the equipment. I had planned to run conduit and then short runs of sealtite from tee's to the solenoids. I believe 18" or less is allowed. If anyone can point me to where I can find more information on the requirements of running explosion proof conduit I'd greatly appreciate it.
