Thank you in advance for any help provided. The situation I am dealing with involves a class 1 div 2 building in which we have quite a few devices that need to utilize liquidtight or something similiar. The manufacturer, upon our request, said that liquidtight by itself would be adequate to run from the rigid pipe to the device (2-3 feet), taking into consideration these devices are at least class 1 div 2 rated. Since then we have been told otherwise. When I look over the 2014 edition of the NEC I feel as though we should be able to use liquidtight as is. At worst I get the impression that a bonding jumper may be required. Some educated input would be great at this point. My "assumptions" are not going to fly with the end user.
More details: This is a combination of building controls and gas/smoke detection systems integrated together. All of the wiring is 18ga or less carrying no more than 24v at probably less than 2 or 3 amps max. Some wires are for power, some are for 4-20ma signals, and some are for contact closures.
Thanks again.
