504.30 (B) states that conductors in an intrinsically safe circuit shall be separated from each other by one of the following means : 1) the conductors are within a grounded shiel. 2) the conductors of each circuit have insulation with a minimum thickness of .25mm.
Does this apply to thermocouples? I have equipment that has Class 1 Div II interior. The only circuits entering the Class 1 Div II location are thermocouples. The thermocouples are ran from the Class 1 Div II interior by through a sealed fitting and then into an IS barrier located on the sub panel. Generally, all of the thermocouples use the same conduit.
Does 504.30 (B) apply to thermocouples? It specifically says "conductors" and gives the exception "Unless otherwise identified". The intent of the thermocouples are not to be a conductor. If I call this out on the control drawing am I able to run them in the same conduit?
