Can someone confirm that multiconductor instrumentation cables (ex. Thermocouple, coax, analog, low voltage 0-10Vdc/4-20mA) can be routed through a sealed conduit in a Class 1 Div 1 area?? Granted the cable ends will also be sealed within the C1D1 area to minimize vapors travelling into the cable core. Is this an approved wiring method in a C1D1 area??
Do the multiconductor cables have to be armored??
I have an Insturmentation Junction box with thermocouple jacks, coaxial jacks, and ms connector jacks inside a C1D1 area, and I am trying to find the best wiring method of getting the cables from the C1D1 area to a C1D2 area.
Any insight would be greatly appreciated.
