EMT question

[Ktdidone]

Can EMT be "fished" in walls?

 

[480sparky]

Certainly. But obvious mechanical restrictions make it difficult.

I think you meant installed in the walls. It will be hard to fish in the walls, but not impossible.

I have pondered this. I do not see any exceptions to the securing and supporting requirements. I once fished 80 feet of 3" pvc. The inspector was ok with it.

works especially well in insulated walls if you have some headroom.
cut in as long of pieces as possible, and couple together as needed.
jam it right through that insulation!

2014 NEC 358.30(A) exception #2.....unbroken lengths (without couplings) of EMT shall be permitted to be fished.
It can be fished, but might be tough.

Ponder this...LOL. So it can be fished but no more than 10' unless you have 20' length of the stuff.

358.30 Securing and Supporting. EMT shall be installed
as a complete system in accordance with 300.18 and shall
be securely fastened in place and supported in accordance
with 358.30(A) and (B).
(A) Securely Fastened. EMT shall be securely fastened in
place at least every 3 m (10 ft). In addition, each EMT run
between termination points shall be securely fastened within
900 mm (3 ft) of each outlet box, junction box, device box,
cabinet, conduit body, or other tubing termination.


Exception No. 1: Fastening of unbroken lengths shall be
permitted to be increased to a distance of 1.5 m (5 ft) where
structural members do not readily permit fastening within
900 mm (3 ft).


Exception No. 2: For concealed work in finished buildings
or prefinished wall panels where such securing is impracticable,
unbroken lengths (without coupling) of EMT shall
be permitted to be fished.

Forgive me, but who would ever know there was a coupling down the wall? I know, I know, I'm a baaaaddddd boy

Interesting, I didn't know. I respect the code for the most part, but I would do it again without hesitation!

Um, if the wall is more than 20 feet tall, what did you do, use an EMT stretcher?

I guess you would have to use another wiring method or be non-compliant.

BTW, welcome to the show
