Re: ENT in hazardous locations

prograd,
I see no conflict between the 2 sections that you cited. They both prohibit the use of ENT in Class 2 locations.

Re: ENT in hazardous locations

I guess my question should have been whats the difference between ENT and "liquidtight flexible nonmetallic conduit with listed fittings" as is accepted in Class II locations as per 502.4 (A), (1), (e).
 
Re: ENT in hazardous locations

ENT is the blue "smurf tube" as we call it [NEC-362]....the flexible conduit talked about in NEC-502 is LFNC [NEC-356]...one different is one is tubing and the other is conduit.....[there is a different even though people call it all conduit]
 
Re: ENT in hazardous locations

The reason I ask is that I have samples of flexible non-metallic conduit, or tubing, that have been retreived from a fire. The fire occurred in a Class II hazardous area. It is alledged that the electrical wiring may have contributed to the fire's origin.

The samples are 3/4" and corrugated on both the inside and outside. They have no inner sleeve. They can be bent by hand, and crushed underfoot, but are too rigid to crush with one hand. I do not have a sample with markings on it.

After reviewing NEC-356 I am leaning towards LFNC, but is there a way that I can tell for sure?

Does the simple fact that I have retreived samples from a fire scene confirm that they are LFNC?
