Hello,
I am installing a new bathroom fan in my second-floor bathroom. The
fan has a light and nightlight that are all capable of being powered
by separate switches. In order to support this, I need to run new wire
up from the switch, into the attic, and over to the fan.
My question is what is the best way to do this, in terms of conduit,
wire type, etc? I figure running some Romex through PVC conduit would
be the best bet, especially in the attic. However, what about in the
wall? Can I have unsecured Romex in there? If I ran PVC the 4 feet
down the wall into the switch box, is it okay to have that unsecured?
Thanks...
Jason

Unless you are someplace strange like Chicago, that requires everything to
be in conduit, no need for conduit at all. Just run it like the existing
wiring is run. Main reason for stapling romex off to the stud is so the
drywall screws won't hit it- on old work where the drywall is already up,
that is not an issue. I added a switch leg here to do the same thing, put
the lights and fan on seperate switches. I just drilled through top plate of
wall, and fished it down to the enlarged hole where I would be placing the
2-gang old-work box. Best to fish before installing the box- much easier to
get it through the knockouts.
BTW, based on numerous threads on here, you can't run romx through conduit
anyway, other than short runs like down a basement wall to a surface-mounted
outlet. And for that, you have to have a bushing on end to avoid abrading
the plastic jacket.

Oh, geez, here we go again. Why do people keep saying this? It's NOT TRUE.
Romex *is* permitted by Code to be installed in conduit, in any location where
it's permitted to be installed withOUT conduit, without regard to the length
of run.
Anyone who disagrees is invited to cite the article of the National Electrical
Code which shows otherwise.

That, at least, is correct.

If you say so, Doug- that is why I included the disclaimer 'based on
numerous threads on here'. This is the first time I have heard anyone on
here claim is was legal, that I recall. (IANAE, etc.) Other than a short
run, it would be a PITA to pull through typical small EMT, wouldn't it?
But in OP's case, I still think it isn't needed, unless some local code
requires it. Just match what is there already.

Well, this isn't the first time I've posted that here, or the second, either.
Might be the tenth or twelfth by now...
Nobody's been able to come up with a Code cite yet.
Not only is it legal to put Romex inside conduit, in some cases it's
*required*.
>(IANAE, etc.) Other than a short
>run, it would be a PITA to pull through typical small EMT, wouldn't it?
Yep. But it's Code-compliant.
>But in OP's case, I still think it isn't needed, unless some local code

Oh, I agree, it isn't needed, given the OP's description. But it's perfectly
legal.
