I've always thought it was appropriate that the Washington State codes were called WAC. I'm pretty sure that's short for "wacky".
 
Are you calling "Careflex" Electrical Nonmetallic Tubing, or Liquidtight Flexible Nonmetallic Conduit? In Florida "Carflex" is LFNC. Does anyone know where the name Careflex came from?

Carflex is the brand name for Carlon's LFNMC.
 
we interchange the terms Sealtite and Carflex and Liquidtight. I guess they are different. I don't know the difference.

Sealtite has a metal spiral inside, carflex does not. :)

They are covered by different sections of the code as well.

How do the acronyms line up with the terms I mentioned?

Long article. I know the EMT and MC sections by heart because that's 95% of what we run. You can quiz me on straping distances, suitability for grounding, et al, ad nauseum.

Never paid too much attention to the LFNMC and LFMC sections. Sorry. ;)

I was just teasing you by the way... ;)
 
I have learned one thing about Carflex: It has more internal friction than anything else on the planet.

If it has a bend or two in it, it's a royal pain to feed a fishtape through, and not much better for pulling.

I notice it goes one way better than the other, other than that, I know its gross but a little spit goes a long way...

The LFNC (Carflex) can be used.

However, running service conductors 10' through a crawl space would be a violation in many areas. 230.70(A)(1)
