    Can you please send me email and I will have local Emerson office to assist your specific need. Is this pertaining to DVC?

    Narendra Babu,
    Let me provide generic answer. There is no restriction as to what type of electrical entry thread (M20 or NPT) you put Flameproof or Intrinsically safe product enclosures.
    In past Emerson - Fisher, DVC had simply elected to offer just NPT connections. This is changing and we are adding M20 as an optional threading.
    Can you please provide your email ID and world area, enabling our sales channel to contact you.
