Ideas on running Wiremold across crown moulding

Hello all,

Would really like to hear some opinions on this situation!

I am doing some work in my brothers apartment and one of the rooms I will be using wiremold to install a switch and ceiling fixture. Going up from the switch box to the ceiling fixture I will have to cross crown moulding. It is not big, from vague memory i'd say about 3 inches out both ways with a shape of a quarter circle and flat parts at the edges. Something like a quarter pipe that skateboarders ride on. I'm not too fond of the idea of buying a wiremold bender (I almost never deal with Wiremold) but just might if its the best option or at least see if i can borrow one from somebody.

So far my current plan is to get the Milwaukee M18 Oscillating tool to cut a small channel in the crown moulding so i can put a Wiremold "inside elbow" in the channel that I removed.

How would you guys approach this situation?
 
I've done them with i/2 emt bender as Jumper says, usually get passable bend but its hard to keep wiremold from rolling sideways and ruining bend

but that notch in crown mold may look better anyway
 
Rent or borrow a 500/700 WM bender.
It's still going to look ugly though.

How about something like this? I ran across this one doing a search.
Wireless remote control wall switch.

What type of ceiling fixture are you using? Can you hide the receiver in the light canopy?
 
Or, notch the crown, lay the WM, then restore the contour of the crown with wood filler, Bondo, joint compound, etc.

The finished product would resemble the back-notched crown suggestion, but with less work.

Pretty sure not legal. I think 90 has to accessible.

Unless this is correct, of course.
 
Whatever you do at the crown molding it still won't look as ugly as the wiremold running "naked" across the ceiling!:happyno:

If there is power in the ceiling I would get a universal fan remote and put the receiver above the light or in the attic. You can mount the transmitter beside the door or wherever you choose.
 
Umm, I'm sure the OP has thought of this, but why cant you fish the walls/ceiling vs using wiremold?

What I'd do if having to use WM is where it crosses the crown molding, use a oscillating tool to plunge cut out the 1" or so piece of crown completely out, run the WM, then use the same oscillating tool to trim the extra wood from the back of the cut section of crown so that it sits flush on the WM, glue that to the WM, then caulk/paint it all.

I dont think WM 90s have to be accessible any more than an EMT sweep 90 has to be accessible. It's not a condulet, there's no splice there. If it does have to be accessible, skip the caulking part, then the 90 is accessible w/o removing building finish (the cut piece of crown is now attached to the WM not the wall ).

eta: I suppose you could also use 3 90s back to back to back and bypass the crown altogether. Ugly, but no cutting the crown.

It is a pull point.

If you install it, gotta be accessible. Surface Mounted Raceway.

Ah, so if this an Article 386 installation, then 386.12(5) prohibits installation where concealed, except as permitted in 386.10, which deals with passing transversely through walls and floors with an unbroken piece. So that would prohibit concealing the 90. I don't see what being a 90 or a pull point has to do with it.

My point about required pull points is that I would think that if, say, you ran out of EMT couplings and had some extra EMT C-condulets, you could use a C-condulet instead of a coupling, and if you didn't need the pull point, then you could conceal the C-condulet. But maybe that's wrong?

Cheers, Wayne

How would you install conductors in that 90 without using it as a pull point?

And yes also to concealing here with broken lengths.

No.

314.29 Boxes, Conduit Bodies, and Handhole Enclo- sures to Be Accessible. Boxes, conduit bodies, and hand- hole enclosures shall be installed so that the wiring con- tained in them can be rendered accessible without removing any part of the building or structure or, in underground cir- cuits, without excavating sidewalks, paving, earth, or other substance that is to be used to establish the finished grade.

and if you glue the little cut piece of crown to the WM, and dont caulk it, it's still accessible and meets 314.29, yes?
