I thought for sure I had read a scenario similar to the one I am about to present somewhere on this site, but I haven't been able to find it so I am going to pose the question (again possibly).
Assume one was to install an explosionproof instrument (no other ratings, not factory sealed or anything else, just explosionproof) run in conduit in a Class 1 Div. 2 area without a conduit seal at the instrument.
Is the installation still acceptable for a class 1 div. 2 location?
I feel that it is obvious that it would not be explosionproof anymore - but what is it now?
I say, without the seal, it is not good enough to install in a class 1 division 2. Without a seal at the entrance of the instrument, an explosion can no longer be confined to the instrument and may propagate through the conduit system causing issues elsewhere.
Your thoughts?
