hello

Please provide the chapter numbers pertaining to both 'smurf' and greenfield.

What do Chaps 348 and 360 refer to? Chap 348--FMC--sounds like greenfield, both so does chap 360--FMT. Chap 362 seems like it might refer to 'smurf'. Please advise.

also...does chap 356--LFNC--refer to 'Carflex', i.e., like 'Sealtight' but having no flex armor inside?

thank you

Since they are slang, there may be some variation.

Greenfield, to me, is FMC Ch 348. The very same stuff we also call 'flex'.

Smurf tube is ENT Ch 362, specifically the blue stuff made by Carlon.

Nothing says that ENT has to be blue.

Also, if you are not sure what a person using slang means, ask them to give you generic name, the one that you would find in the code book. The labels on the cartons don't have the slang names on them unless you are getting the 'real deal', like Romex brand cable. Most slang comes from decades ago and was meant to describe a single item made by a particular maker, like 'mini's'. Minerallac makes a lot of stuff besides pipe hangars, but most know that a 'mini' is a certain type. Also, if Appleton makes the same thing. Are those 'mini's', too?
 
Art 356.

What we call Sealtight is LFMC. Sealtight also makes LFNC and it even says Sealtight on it.

Again, check the label. If it's listed, the name you can find it in the NEC will be on the label.

Slang terms vary from place to place. Since I traveled a bit, I just stuck with generic terms until I knew for sure what they were talking about. For instance, the same term is used here to mean a large multiconductor NMS cable as it is in Gary for large single conductor diesel locomotive cable.

thanks for the speedy reply!

What, then, is FMT --'flexible metallic tubing? What is the difference between 'flexible metal conduit' (FMC, chap 348), and 'flexible metallic tubing' (FMT, chap 360)--as far as the mechanic on the job is concerned?

also...the product we on the east coast referred to as 'Carflex' --Sealtite, but without the metal coil tubing inside--would be what via the NEC--LFNC (liquidtight flexible non-metallic tubing)? That is chap 356.

Best,

Dean

most these products have the generic or NEC name printed right on the product or on packaging, same with associated fittings.
