Smurf (flex ent) use Code clarification
 
HI;

In the garage, the ceiling is unfinished, just open joists. It is not going to be finished. This is a residential garage, for parking cars, no work shop or anything special in this garage; 2 cars, some storage, and a 240v compressor.

I am wondering if it is considered acceptable to run "smurf" in the ceiling, even though it is exposed, if I keep it between the joists and drill holes where it crosses the joists?

Also, when I come down to just below a joist to a junction box, can the smurf dip just below the joist at that point to enter the jbox? or does it have to stay between the joists entirely.

I'd use EMT on the walls, for the drops down to the panel and to the switches / outlets. It's just in the ceiling and in the attic that I was thinking of running EMT. I was just looking to save a little time over using EMT for everything.

One other quick question on smurf, can it be used in a crawl space below the joists? What if I keep it at the running board?

Thanks
Jamie

In my area I would just use NM... :) As long as the garage was attached anyways.

If it was detached it would need a 15 min finish rating, right?

Yeah, that pesky code issue. I never see anyone enforce it though.

Stupid me. Forgot to say it is detached.

Jamie, Now that you are getting pipe bending experience why not use pipe? Looks better than smurf or NM. I don't see much added time. Pick a method that serves you best and stick with it.

Why not? Conduit looks good:thumbsup:

Your right, EMT does look nice, I like it alot. My dad had asked me about using some more smurf to save time, and I felt compelled to at least ask you guys about it.

After my dad spent about 4 hours trying to fish a wire today, I showed him how to save some time, it involved a sawzall :whistling2:

I am amazed at how fast my dad can plaster, Just an hour or two after my demo work, aside from the paint, you could barely tell anything happened to that wall, tomorrow it will be painted and will look like it always did.
