I'm sorry I haven't reply, I sent a note to the NEC and was waiting for a reply. Sorry. One of my concern is on longer lenght, we have ended up with water in the flex and are having shorted wiring in long runs. This is extremely dangerous in a Div 1 area, can be bad in a Div 2 area. Our Flex has the metal rib inside, this isn't plastic flex. I would appreciate any reply witha referance so I can share with my folks. Here is the type of flex we used. Thanks.
