I have a sump pump room that the engineer has classified as cl I div II. The state or anybody else does not consider this room classified at all but it doesn't matter because we are building it to what the engineer wants. My question is am I required to provide a seal at the point of entrance to a explosion proof incandescent light fixture that has MCHL (cable requrement) as a wiring method which originates outside the classified area and is sealed within 10ft of this bounry in a gutter outside the classified area. I do not have my code book infront of me but when I looked it up I believe it said that cable must be sealed at an eclosure that is explosion proof rated at the point of entrance. The cable is actually less then ten feet from where it enters the classified area to where it terminates at the fixture so it was done with a seal at the boundry only and not at the fixture. I think that if I sealed it at the fixture only I would have satisfied two requrements since the length of the cable is less then ten feet. What do you think? Do I need a TMCX connector at the fixture in addition to seal at the boundry?
Also is there any requirement that says a TMCX connector cannot be consealed in a wall space? No one will ever know it is there except the inspector that saw us install it. Thank you.
