I have been trying to find in the code book where it say's specifically that LFMC ( sealtite) cannot be used in a Class-1, Div-1 area. The only reference that I can find close is 510:4 which has references to flexible connections. I always assumed that you could not use sealtite in a Div-1 are for two reasons. ( 1 )Mitigation of gases ( but code says the fittings do not need to be for that ares classification) and ( 2 ) because if there is a ground fault seperation of the convolutions could cause and arc / explosion as stated in 510:4 in the exception area ( blue highlighted area).
Is this assumption correct.?
