My understanding is that the entire LNG dispenser enclosure and the surrounding area for 5' in all directions from it is a Class 1, Division 1 location. If a lighting conduit emerges from grade (1"RMC) located about 12" from the dispenser and extends to 10 feet above grade, and the dispenser is 6 feet tall, that places the end (top) of that conduit in the Division 1 location (4' above dispenser). If a light fixture is installed at the top of that conduit and is listed for Class 1, Division 2, that is a violation. If that same conduit was extended to place the light above the 5 foot boundry, (let's say - 10' above the top of the dispenser), placing it in the Division 2 location, and assuming there is a coupling somewhere in the Division 1 area, would a seal be required since the conduit is leaving a Division 1 location and running to a Division 2 location? These are all meant as questions, not statements, since I am trying to make sense of it. Any help would be appreciated. The part that is the most fuzzy to me concerns seals when leaving a division 1 location and entering a division 2 location. Thank you
