Class I, Division 1, Group D & Class II, Division 1, Groups E, F, G Junction boxes.
I am designing a system that is in a Class I, Division 1, Group D & Class II, Division 1, Groups E, F & G hazardous location.
My main panel is x-purged and all the inputs on the machine are intrinsically safe and wiring to isolation barriers in the main panel.
My outputs (hydraulic and pneumatic solenoid valves) are explosion proof with an 18" potted cable coming off of the coil.
My potted cable is not long enough to go all the way to the main panel, can I use a standard NEMA 4 junction box with terminals snf seal-offs entering and exiting the junction box to the main panel? Or, do I need to use an explosion proof junction box as my termination point for the valves?
Thanks, Dan
